Dan's story about making a wallet with the laser is amusing: https://www.youtube.com/watch?t=292&v=0R3mMUsHFvU https://www.youtube.com/watch?t=292&v=0R3mMUsHFvU "No, I have a laser!"
- vvanders 11y ago
  I feel like that's almost the answer to anything.
  - knieveltech 11y ago
    Only true if you have a laser and don't fully understand what's possible with a hammer.
- pavel_lishin 11y ago
  That's pretty great; honestly, if it weren't for the cloud-connectedness, I'd consider buying it based on the strength of that story alone. (I do wonder what the costs of leather and fake leather are, and what the market for fancy laser-etched wallets is...)
- harryjo 11y ago
  Why would a making a wallet require "half a cow" ? Is making a leather wallet as nearly-impossible as he claims? http://www.instructables.com/id/How-to-make-a-leather-wallet-2/ http://www.instructables.com/id/How-to-make-a-leather-wallet... The video feels like infomercial schtick.
- markvdb 11y ago
  Luckily, he knew to use natural leather. Synthetic "leather" is known to produce extremely poisonous cholrine gasses when being cut...
mlmilleratmit 11y ago
I ordered one, wish I could pick it up in person instead of paying the shipping. Particularly interested in seeing what one can do with just a pen and skipping the computer design stage...
cfontes 11y ago
Fuck, I hate not living in the US when things like this appear.
- chromaton 11y ago
  You can always order a Chinese made laser cutter which has 80% of the features and 100% of the most important ones. If you go this route, get it from a dealer in your country with a good reputation so you can get service and support.
- marcosdumay 11y ago
  Worst part is that if I try to buy something like this in Brazil, it'll probably get apprehended by customs as a dangerous item.
  - chromaton 11y ago
    If there are no importers/dealers in Brazil, this is a business opportunity to import machines from China.
    - cfontes 11y ago
      It's Brazil... This would be a nightmare to make happen, you would need to bribe so many people to get a shipment here that your profit would be unworthy and also make you a criminal or you can run it by the lawn and never get the items or pay 100% taxes over them + their shipping costs making a machine like this cost U$5000,00

        I am Brazilian and I second this message.
    - outworlder 11y ago
      An opportunity? Let's see. There are lots of customs fees involved that are not considered taxes per-se. But let's ignore them and look at taxes: You get a 60% import tax right off the bat (this applies over the product cost, the aforementioned fees AND shipping). Then, there's ICMS, which varies by state (let's say, 12%). There's also IPI, which is variable according to the product and I'm not sure where a laser cutter would fit in. Also PIS (1.65%), COFINS (7.6%) and IOF since it probably involves currency exchange (0.38%). Speaking of that... there's the unfavorable exchange rate. Today, the real hit a high of BRL 4.23 for one USD. It was 2.50 something one year ago, and then the economy blew up. I'm not going to the trouble of trying to calculate the final price, without the importer's markup, but it will be HIGH. Good luck marketing this thing to anything other than medium businesses. And that one year from now. You'll spend like an year incorporating your company and navigating the customs law mess. There are other options, of course. Manufacturing locally would bypass a lot of taxes (and generate others). But then you could negotiate deals with local authorities in exchange for job creation and some strategic dinners. That sort of stuff. The opportunity cost of doing that is just huge and, by the time you managed all that, you'd be profitable in several other countries already. Then you'll have to deal with the crappy transportation infrastructure. Forget shipping things by train, you'll have to use trucks. Delivery estimates of 30 business days are not uncommon at all. My advice? Stay away from Brazil. Even more so this year. There's a reason investors are pulling money out of the country. Disclaimer: I'm Brazilian.

In the video, at about 13:40 they reveal that to print you have to use the web interface which runs "On Googles Cloud". I would not like the interface to my own printer to be "In the Google cloud". Does that mean when the company goes out of business, the printer is bricked? And right after, they admit that they plan adding paid services. Oh oh. How will thesed paid services be announced? I can imagine how. Whenever I want to print, this thing will bug me to pay for some fancy addon. And privacy? Goes right out of the window. Everything I print would go through all kinds of hands. The manufacturer of this printer, Google, my carrier and who knows who. And what about security? This is probably a full blown computer they want me to give access to my lan and internet connection. Who guarantees it gets security updates?
- mlmilleratmit 11y ago
  Good question, I _think_ the ideas is the exact opposite -- you're not depending on Glowforge UI to be backed by a startups servers, the software runs on google cloud instead. Pros and cons, obviously, but I think the main pro is (like a Tesla) the machine's performance and usability can be improved without you installing any new software. As far as dependencies go, google's probably the best possible choice.
  - ISL 11y ago
    Do you know if they provide direct hardware hooks, too? I've not met a precision cutting or metrology tool where we didn't need to get low-level access to the hardware to get simple things done....
    - mlmilleratmit 11y ago
      Good question for somebody on the GF team. My last company was Cloudant so my biases are pretty obvious.
      - mdturnerphys 11y ago
        Hey guys! :)
cptskippy 11y ago
It's not just cloud connected, it's cloud dependent. It requires internet access and their cloud services to function at all. That's kind of disappointing.
- lcswi 11y ago
  That's why I like to read comments before clicking. Thanks for saving my bandwidth. What a shame.
- riebschlager 11y ago
  Do you have any details about this? I can't seem to find that on their site. But yeah, if that's true it's a real buzzkill.
  - 3dfan 11y ago
    They say so here at 13:40 https://www.youtube.com/watch?t=292&v=0R3mMUsHFvU https://www.youtube.com/watch?t=292&v=0R3mMUsHFvU I said so in a comment half an hour ago, but it immediately got downvoted to oblivion. Meanwhile the comment seems to slowly recover. Nowhere on their website they say so. I would be really pissed if I bought a printer for thousands of dollars, unpack it and then realize I cannot use it. Letting it use my internet connection and being dependant on the services of a company to use it would not be an option for me.
    - cptskippy 11y ago
      Yep, that's where I heard it. I doubt many people listened that far into the video which is why I came back and posted it.

It's a very polished product, and the "pen" mode is a cool idea. To me, they're targeting an odd demographic, Makers who can afford expensive toys / tools, but also want a very friendly, hands-off interface. I would have expected the Maker camp to be ordering ~ $700 40-50W laser cutters from Shenzhen. I suppose the Glowforge would be pretty great in a school setting, though.
- codazoda 11y ago
  I'm a maker. Tell me more about this $700 Shenzhen laser cutter? I googled it and I'm coming up with a few things, but only very small $400 units and very big expensive units.
  - chromaton 11y ago
    CamFive sells a variety of machines. You might try them.
  - Ccecil 11y ago
    Pretty sure they are talking about the K40 "blue box" laser. I have heard they require some mods to get working properly but for the price some think they are worth it.

        samstave 11y ago
        How big is that one on Ebay? I don't see any specs. Also - if you click on Shipping -- it says "free shipping" then it says "$300 shipping" Which is it?
ISL 11y ago
How is a 40W laser Class I, but the 45W laser is Class IV?
- danshapiro 11y ago
  (ceo/cofounder here) You're right - it's the passthrough. CDRH is very strict about what could count as human access. We have some clever interlocks in place around the passthrough but if an examiner can place a mirror in the interior and measure laser output above the threshold without triggering the interlock, you're Class IV.
- mlmilleratmit 11y ago
  This one I actually know -- biohazards depend on more than just wattage -- spot size, wavelength, pulse characteristics, etc, all go into it. I think you really compare them based on the Poynting vector. Disclosure: I'm a GF backer and am a card carrying physicist who had this question on his qualifying exam in grad school. https://www.rli.com/resources/articles/classification.aspx https://www.rli.com/resources/articles/classification.aspx
- aidenn0 11y ago
  You can get Class I by preventing human access, I'm guessing the Pro can't have the same interlocks for some design reason.
  - mlmilleratmit 11y ago
    I think the pro is 'feed-able', wonder if that's it.
    - aidenn0 11y ago
      Yeah, I just saw that on their youtube video; the sides can remain open during operation to allow etching/cutting of materials larger than the enclosure. That means human access is possible, so therefore the class IV.
Someone1234 11y ago
I am surprised it can cut paper without causing ignition. I wonder how many of the projects shown were created using the "basic" ($2K) version and how many were produced using the pro ($4K) version? I will say their early bird prices make these compelling for small business/etsy setups. However once they go to full price, I don't know if that will remain as true. It would take a LOT of wallets to break even at a $4K buy-in for the "basic" version. PS - We live in an exciting world. Between 3D printers and these, you really can do more at home than ever before. And this type of technology is bringing tooling prices down massively even if you have it fabricated. PPS - Looking at the material costs on their page, and looking at how much these items sell for on etsy right now ($39 inc. free postage), you'd have to sell over one hundred hardback skins for a Macbook Pro just to break even (and that's ignoring many of the hidden costs of running a business, like accountant, licensing, your salary, etc).
- danshapiro 11y ago
  (cofounder/ceo here) I don't remember which sample items we made on which model, but everything you see is printable on the basic model. For example, the monitor stand and dollhouse don't have pieces larger than 12x20.
- jay-saint 11y ago
  A 100 unit break even point is incredible low. Have you read many of the write ups on product based Kickstarter campaigns. From what I have read most break even point are into the 1,000 plus units if you have to account for fabricating molds or dies. Then these mold and dies can only be used fro one project. That is the beauty of 3D printing, laser etc. You have one tool that can be used to fab hundreds of designs or product with no tooling costs.
- outworlder 11y ago
  > I am surprised it can cut paper without causing ignition. As a kid, I had a lot of difficulty trying to ignite paper with lenses under the sun (white notebook paper). I then gave up and used the lenses for cutting instead. So I'm not that surprised. To this day I wonder what would be the correct set of conditions that would make it easier to combust. I remember trying black paint - that only made the cutting part easier.
knicholes 11y ago
It calls itself a 3D laser printer. It's a 2D laser cutter.
- MajorLOL 11y ago
  ...yeah. I was just thinking the same thing.
- abtinf 11y ago
  It doesn't just cut. It has variable focus of 13mm, allowing it to carve out any desired shape within that range.
  - Pxtl 11y ago
    Fine, cutter/engraver.
- technomancy 11y ago

ZenoArrow 11y ago
Could you use this for single sided PCB printing?
- mmastrac 11y ago
  In theory this process should work (it still requires etching as you can't cut copper with this laser): http://www.instructables.com/id/Custom-PCB-Prototyping-using-a-Laser-Cutter/ http://www.instructables.com/id/Custom-PCB-Prototyping-using...
  - thrownaway2424 11y ago
    That seems like a lot more effort than traditional photoresist printing that you can do with an inkjet printer (or just freehand with a marker).
hamoid 11y ago
Laser cutters generate smoke (with possibly toxic particles). They have air extraction attached to them for that reason. No air extraction on this model?
- hamoid 11y ago
  I had missed point 12 (air filter upgrade), and non of the pictures showed an exhaust tube...
- mlmilleratmit 11y ago
  Take a look at the specs -- you can either vent them out a window or buy the air filter (which I'm guessing is a fancy charcoal scrubber, don't know for sure).
- tomwphillips 11y ago
  I came to say the same thing. My lab uses an industrial laser cutter a lot, and perspex fumes stink. We have a large extraction unit to capture the fumes. Filters only capture a limited range of compounds too. Important to always check whether the filter can handle the material before cutting.
littletinman 11y ago
I want... NO.... I NEED this! The price seems surprisingly reasonable for the amount of household items you could create that you "Forgot to get from the store."
- danshapiro 11y ago
  (cofounder here) Thank you! I was lucky enough to have an industrial laser in my garage for a few years and was amazed at what it could do, and how miserably hard it was to do it. Hopefully we'll let lots of folks experience the first and none the second.
  - littletinman 11y ago
    I hope so! As a kid, this would have realized so many dreams! Going on my list of tools to get!
tommoor 11y ago
After watching that video I feel like they should do a promo with Etsy. Also can't help but think about Cory Doctorow's "Makers", sci-fi being slowly ushered into our lives :)
uptown 11y ago
One of their sample images appears to be of the "Below the Boat" series. http://www.belowtheboat.com/ http://www.belowtheboat.com/ I've given those maps as gifts, and they're very nice quality. Is there any relationship between your companies? Are they using your laser cutter?
- danshapiro 11y ago
  (ceo/cofounder here) There are lots of folks doing bathymetric maps with lasers; I don't know who was first to it. We generated ours from scratch from NOAA data, but owe them (or whoever did it first) a debt of inspiration.
- smackfu 11y ago
  The problem with making something out of public domain maps using technology is that it's very easy for someone else to copy it pretty effortlessly.
chromaton 11y ago
This looks like a decent laser but I thought I'd post a few thoughts about this package which might give a potential buyer pause. First, the main unique feature I see is the built in camera which apparently gives you a preview of cut/engraved finished part on your computer screen with the material as it's positioned inside the machine. This also (apparently, it's not clear), allows you to correct for misaligned material inside the machine. These are nice features, but it's perfectly possible to cut and engrave without them. One big problem with operating this inside your home is the fumes. Now, they do mention that the base unit needs to be vented to the outside. What this means is that your neighbors (and you, if the wind is right) will have to smell the exhaust from this machine. It's not a nice smell if you're cutting acrylic. Though I personally got used to the scent of vaporized acrylic over time, your neighbors might not be so inclined. So they also offer a $500 add-on ($1000 regular price) to filter the air so you can exhaust inside. The add on is smaller than the already small laser cutter. This is quite a feat and I would really like to know how they got it to work. You see, the fumes/smoke from a laser cutter can really clog up a particulate filter pretty quickly. Wood produces wood smoke, and acrylic vapor is quite sticky when it settles. So you have to have a powerful pump to draw the fumes through the filter. Then you need a good amount of activated charcoal to get rid of the smelly stuff. If you look at the professional model air filters, they're $2000+ and you have to buy filters and media regularly. Laser cutters get messy inside, so if you buy one, be prepared to clean it out regularly to keep the optical and mechanical components clean. Problems with operation can START A FIRE, so be prepared to watch the machine 100% of the time while it's cutting.
- noobermin 11y ago
  Every issue you mentioned apart from the terrible fumes are problems that already exist in one's home with cooking in your own home, and people, seeing the convenience of cooking in their homes, have adapted to it. Regarding fumes actually, the smell from my neighbor's cooking isn't always to my liking either, but, perhaps, burnt plastic might be worse and equally undesirable to all people.
  - elecengin 11y ago
    I think one thing that was not clear are the fumes are extremely toxic. Rarely do you cook where the fumes could make you go unconscious or cause long term health effects.

I have a 40W hobbyist laser cutter. It's fun, and a great tool for various projects, like making board games[1,2]. That said, sometimes materials inside the machine catch fire, and sometimes the beam reflects or dwells on a section of the metal enclosure. It's interesting that they've chosen to make the entire (?) enclosure out of plastic, itself a combustible material. I get why they went with plastic (cheaper to fabricate once you have the molds, lighter to ship, perhaps better dimensional accuracy than cheap sheet metal), but it does not seem particularly safe. The also seem to gloss over the need to ventilate the machine. Plastic fumes are nasty to breathe, glue-bonded wood (think thin plywood) can release formaldehyde fumes, leather may be dyed with heavy metals. What the laser doesn't cause to combust cleanly, it vaporizes. You don't want those emissions in your house of office, and you want them vented away from the optical components as quickly as possible so there is no deposition onto mirror or lens surfaces. Another benefit of metal enclosures is shielding the power supplies of these things. High-voltage laser power supplies are noisy, and when you PWM them, they can cause quite a bit of interference. Metal enclosures at least help to attenuate RF emissions. The "macro camera" is a clever addition for closed-loop optical control (if it is being used for that). Reminds me of attaching an optical mouse sensor the the lens sled. 1. https://igcdn-photos-b-a.akamaihd.net/hphotos-ak-xfp1/t51.2885-15/e15/10549813_673074649438401_1078246007_n.jpg https://igcdn-photos-b-a.akamaihd.net/hphotos-ak-xfp1/t51.28... 2.

- borgel 11y ago
  What unit do you have? I've been thinking about getting one.
  - tomkinstinch 11y ago
    I have an older one from Full Spectrum[1], from when they were adding their own control PCBs to generic units imported from China. The newer ones they have look nicer. There are a few other options on the market now, so it's probably worth shopping around. Larger cutting areas are nice, if for no other reason than that they limit the number of cuts you have to make on raw materials to get them to fit into the machine. I made my own recirculating laser tube cooler using desktop PC water cooling components[2]. Beyond board games, they're useful for making tools for other projects. Need a drill guide with precise spacing? No problem, cut one out on the laser cutter. Need to prototype a coarse-pitch circuit board but don't want to wait for OSHPark or pay for a quick-turn fab? Ablate black paint off a Cu-clad board and chemical etch. Want to de-cap IC packages? You can, with some care. Interested in prototyping microfluidic structures? Sandwich some cut sheets of double-sided tape between acrylic sheet. Need to make a quick enclosure for a project? Design a box [3,4]. Cut the sides out of acrylic, and bond with dichloromethane (with ventilation!). It's great for making fixture components for things like robotics since you an easily include holes for machine screws. They're also fun for cutting leather, cloth, etching aluminum laptops, making gifts, etc. If you don't have access to nice commercial CAD software, DraftSight is a free AutoCAD clone that works fine for 2D drawings[5]. Otherwise, Inkscape works well for 2D, and for 3D, Rhino[6] has an affordable educational license that permits commercial use. 1. https://fslaser.com/Products/Lasers https://fslaser.com/Products/Lasers 2. https://github.com/tomkinsc/Laser-Cooler https://github.com/tomkinsc/Laser-Cooler 3. http://boxmaker.connectionlab.org/ http://boxmaker.connectionlab.org/ 4. http://www.makercase.com/ http://www.makercase.com/ 5. http://www.3ds.com/products-services/draftsight-cad-software/free-download/ http://www.3ds.com/products-services/draftsight-cad-software... 6. https://www.rhino3d.com/ https://www.rhino3d.com/

  - bborud 11y ago
    The TL;DR is that she was part of creating a toxic environment within the company, shipped a product they knew was defective (Makerbot fifth generation), misled the shareholders (of Stratasys) and ultimately cost Stratasys hundreds of millions. For the slightly longer version the class action lawsuit conatins a lot more detail: http://www.adafruit.com/pdfs/makerbot/classaction.pdf http://www.adafruit.com/pdfs/makerbot/classaction.pdf You can also check out Glassdoor reviews: http://www.glassdoor.com/Reviews/Makerbot-Reviews-E480203.htm http://www.glassdoor.com/Reviews/Makerbot-Reviews-E480203.ht...

That's a nice unit, and adding a camera is a big step forward. More CNC machines should have cameras to aid in alignment. I'd really like to have a camera with high magnification on a CNC mill, rigidly mounted a known distance from the spindle, and cross-hairs on the monitor.

linkydinkandyou 11y ago
I've worked with Laser cutters and, unless they have fixed things, you really don't want to be cutting items--especially paper and cardboard--without industrial "shop" ventilation. And many times I've set my work on fire.
mindo 11y ago
Looks like a great toy until you go through comments here. Honestly would have bought this for my woman, since she's into crafts and stuff, but cloud-only cutting/engraving, comments on fumes and filters + dealing with customs (if they even shipping int) quickly changed my mind. I've seen laser engravers on kickstarter before, hope to see more machines that do not require clouds to cut/etch a damn thing.
- llamataboot 11y ago
  I really feel like if there are enough of these out there and the company somehow decides to brick all of them (not that likely IMHO) that someone will be able to come up with an open source solution for controlling it. I'd like to know what their privacy policy is but I'm not particularly worried about it becoming a multi-thousand dollar hunk of plastic. I do wonder why the pre-order price is SO much cheaper than the actual price. At pre-order it's a still. At regular price it's kinda a bit meh.
  - harryjo 11y ago
    They want to motivate interested buyers to pre-order. The "actual" price is FUD.
- harryjo 11y ago
  These aren't really for home use. They are for Maker spaces and workshops and schools. Your partner should bring her design to a local workshop to cut, unless she wants to open the local workshop.
  - mindo 11y ago
    It's easy to say bring the design "to local workshop to cut", they are available in US/CA/Europe, but finding one asia or africa, or even smaller european city is hard if not impossible.

This is going to be epic for schools and print-shops. I think only hardcore enthusiasts will want a home-home version of this tech, but I've spent enough time with paper-cutters and cutting out letter shapes that this is really cool. Also, the boardgame industry can prototype cards much better with this - printing out Catan-like hex-tiles and the like.
alexisnorman 11y ago
I can't count the number of times a fire has started in my university woodshop because of smoldering debris and general lack of safety knowledge with laser cutters. I would assume this is something to be aware of with the Glowforge but I don't see any safety information on your webpage. Is this something to still worry about with 40W and 45W lasers?

Is there some strategy for customers once the cloud servers shut down? The company doesn't have to go out of business - perhaps five years have passed and you've moved on to more awesome models. While your business might feel that customers should upgrade to the newest, it's not great that they would be forced to. For instance, when Steam was first released Valve promised that should the authentication servers go down, they would ensure that the games would stay functional without them. This was an important point that contributed to its success.

Can this device cut metals and if so which ones and of what thickness?
- mchannon 11y ago
  A 40W CO2 laser will not cut metals, period. Save yourself the wait and spend $395 on eBay to get a much more sturdy version shipped to your door. It's not perfect but at that price, imperfection is forgivable.
  - thrownaway2424 11y ago
    OK. We have a laser cutter at work that will cut very thin metal stock but I don't know what its power is or anything else about it.

This is a pretty neat product. I especially like the continuous-feed idea. I'd really like to do stuff that involves stainless. What would be the cheapest option capable of doing some reasonable sheet stainess? My wallet is cringing at the mere concept, but maybe I could talk a local hackerspace into doing it or something. I've been meaning to build a CNC mini-mill for a while. I think that seems like a more practical option for stuff that doesn't require intricate cuts. And definitely more affordable.
- theatrus2 11y ago
  A CO2 laser will not cut stainless - it won't even mark steel unless you coat it with a special ceramic. You're looking at a very very large fiber / YAG laser to cut it. A low power YAG laser can engrave steel - commercially these start at about $30k
  - krasin 11y ago
    Technically, the statement "CO2 laser will not cut stainless steel" is not accurate. Stainless steel is commonly cut by 500W-5kW CO2 lasers, see: https://www.coherent.com/Applications/index.cfm?fuseaction=forms.AppLevel2&AppLevel2ID=62 https://www.coherent.com/Applications/index.cfm?fuseaction=f... https://vimeo.com/106264555 https://vimeo.com/106264555 But it's true that sub-100W CO2 lasers are not even remotely capable of cutting steel.
- IshKebab 11y ago
  For sheet stainless you're probably best paying someone to water-jet cut it. Laser cutters that can cut metal are way way way out of the price range of normal people. Also you can't really mill sheet metal. If you want to do something cool and home-made you could probably hook up an electric nibbler to an X-Y stage.
blhack 11y ago
Awesome! I hope laser cutters (which IMHO is one of the most magical DIY tools there is) start getting the same sort of attention that 3D printers have been.

$954 shipping cost to UK. Isn't it a bit high? Also UK regulations says I need to be supervised to use a class 4 laser since I can point it to somewhere I shouldn't. I wonder if that's still valid for an enclosed product.
ape4 11y ago
Whats the purpose of the big button the device? I would have thought starting a print from your computer would turn it on.
- oasisbob 11y ago
  It's the "the cloud can't activate a 40W cutting laser in your home by itself" button. At least that's how it's explained more-or-less in one of the videos. Makes sense to ensure that the operator is in front of the machine and has everything properly loaded before firing the laser. Who knows how much of that is really intended as a security process...
desireco42 11y ago
It looks really amazing, but until it gets shipped and reviewed, it is just a video. I don't doubt they have prototypes nor I doubt their ability to ship, but once you do, then it is a real product.
newmotors 11y ago
@danshapiro Questions : 1) Why could you not have done this with a quad core i7 box running ubuntu? The amount of time it will take to ship information from my box to google cloud is longer than what can be done on my box. What exact monetization strategy made you keep software/data in the cloud? 2) Any ETA on when the machines will start shipping? Assuming you now know how many people ordered already.
xrjn 11y ago
I spend a lot of time playing with a laser cutter (120w generic from China). A lot of the things that they talk about are quite cool, but I think that they do not show all the other parts that also require time and effort - although I do imagine that one of their value propositions is that they remove and/or simplify a lot of the processes and their complexities. One of the biggest issues I currently have is to generate a file that the laser cutter will like - it has to be a dxf with no sub layers or any linked files, or a old illustrator file (.ai version 8). Each "settings layer" has to have it's own distinct color, and sometimes if the colors are too close, they get merged into one. It can also be difficult to set the correct distance between the things that you want to engrave and the things that you want to cut - say you want to engrave a round logo on a round beer coaster: getting this perfect would take a lot of tweaking, as there are minor (yet visible) gaps and mis-alignments. Next, to get the laser to cut properly also takes some tweaking. It's almost impossible to get a repeatable cut, since there are so many different factors that you need to take into play: the location of the item you're cutting on the bed, the temperature of the laser, the thickness and quality of your material, the accuracy of the auto-focus, and the settings themselves. If we look at the location for example, there is a huge difference between the top left corner - where the laser mirror is - and the bottom right corner. On one side your material will catch fire, on the other, it will only cut half way through. The material is also an important factor - if the material is even 0.2mm thicker on the top compared to the bottom (especially true for acrylic), then the laser will go through on one side, and won't go through on the other. For wood, tiny differences in it's quality can have a significant impact on the cut and especially on any engraving you do. With wood and similar, easily smudged materials, you also have this sort of 'caramelisation' after you cut and engrave - the degree of this effect depends on whether you used the right power or not (for which you also have to take into account the location, temperature, material quality,...). If you try to clean it off by hand or with a dry tissue, you will smudge it further and it will be difficult to remove. Instead, you have to painstakingly clean every piece you cut with an alcohol soaked cloth, which will remove most of these smudges - however it won't remove any burn marks. As per the burn marks, you get a lot more of them when you use a honeycomb bed compared to one which has a number of thin pieces of metal that stretch across with a few cm interval. The glowforge laser has this honeycomb bed, so expect your wood, cardboard and paper cutouts to have some of these burn marks if you don't pay very close attention to the power/speed of the cut. With plastic, getting a cleaner cut is a bit easier, but the fumes are horrendous. Also, if you don't cut through the whole thickness of the plastic the first time, and do another pass, the edges which you cut will have these 'micro-cracks' that dont' look very professional. Similarly, if you cut with too much power, your plastic edges will just melt and look quite bad. However, an advantage with plastic cutting is that you can clean it without too much difficulty, if you use sufficient alcohol you can get most burn marks away. Engraving looks really nice when done with a laser cutting, but it does take some time until you figure out the correct settings for each material. I particularly love engraved plastic and wood, the result (especially from genuine, extruded plexiglass) is beautiful and vey professional. A local public figure has had a picture of him holding a laser-engraved logo that I made him as his profile picture. Personally, I made some laser cut business cards, and they have absolutely blown away a lot of people - one person even told me that he stuck it to his wall for inspiration. I've also worked on laser cut tags/tokens that I give out as a promotional gift to people, and then they can use it as a fidelity card when they order things through my startup. I'm still working on perfecting these tags, but they required a lot of testing (over 30 different attempts just to get the QR code to engrave in a readable way), and I still haven't been able to generate them through software (right now they have to be put into illustrator before exporting them to the laser cutter). Lastly, engraving paper will likely incredibly difficult. On their page they have a sheet of paper that they engraved - I want to know how many attempts it took them before they got it to work - especially since the paper gets very easily caramelised. Maybe they had to use a special coating or used yellow/blue painters tape? Despite all of this, laser cutters are extremely cool. The one we have cost $4000, and people have done lots of amazing things with it. Nowadays, you can get a 40w laser from ebay or aliexpress for a few hundred dollars, but do expect to spend weeks figuring out how to use it. The Glowforge looks like a pretty cool idea, however I don't know if they'll be able to survive at this price point + with the technology being at the state it is today. Their software (minus the part where it's cloud based), looks really powerful and very useful.

I'd be interested to hear the benefits over the successful Kickstarter[1] LazerBlade[2], which looks much simpler but is less than half the price at retail.

So in a followup, Glowforge offered to release the firmware of this 3d printer as GPL. That is a ballsy and incredibly great move. It also helps negate the issues of their cloud service going away, I have an expensive paperweight issue. See: http://glowforge.com/gpl-licensed-open-source-firmware-for-glowforge/ http://glowforge.com/gpl-licensed-open-source-firmware-for-g...
- Pxtl 11y ago
  The thing is that their firmware is ultra-lightweight. One of the things they're proud of is that the firmware is extremely thin and basically shunts control signals directly from the cloud service. The cloud service does everything. The expensive paperweight issue still stands.
  - lairdpop 11y ago
    I am not sure that this would be the case. If all the firmware has to do is process G code, that's oh well understood problem, and runs on Arduino's, and whatever is grilling this printer has to be at least as powerful as we oh well understood problem, and runs on Arduino's, and whatever is grilling this printer has to be at least as powerful as Arduino, and he clearly has four more storage since it can buffer print streams coming across the Internet which is a lot harder then coming in local connection. The only limitation I see is that the device does not have a USB port, which means that even if you're printing off-line you're going through Wi-Fi. If the company went under, I'm wondering if the answer wouldn't be to reverse engineer enough of the server-side to print, and run a copy of that locally, without having to change the printer's firmware.

jps8 11y ago
@danshapiro - Thanks for giving a fantastic resolution to the issue of the cloud software. I think that was a big hang up for many of us. Can you expand on the benefits of the Pro model? The usefulness of the included air filter and pass through slots have been explained on your site, but the laser and cooling upgrade aren't really ever discussed. 5W more power doesn't seem like very much of an upgrade (12.5% more power for 60% more cost). What does the Pro model's upgraded laser and cooling specs mean in terms of "usefulness": cuttable material thickness, cutting times, duty cycle, etc? Also, what's the expected life span of the charcoal filters, HEPA filters, laser tube, and any other consumables? Are replacements for these available only through Glowforge, or are they industry standard / Over The Counter parts?
diyseguy 11y ago
It looks like vaporware to me. What gives me pause is the sneaky way they present it as if it were a KickStarter project, but it's not. So all those people shelling out for the early release are not protected if they close up shop and disappear it seems to me. So many glowing promises, but will they be able to follow through on all of them? I dunno. I am skeptical. (I hope they do though, I seriously want this to be real).
g1n016399 11y ago
Thanks for the great discussion, I learned a ton of good info from this thread which cotributed to me deciding to take the plunge and preorder the basic Glowforce.

exodust 11y ago
Disappointed in the pricing tactics, and doubt the "50% off" is anything but typical sales bull. Back in Feb in an interview with Shapiro in the NYT it was stated "desktop laser cutter that it plans to sell for around $2,000". No mention of this being a special 50% off price. And in May this year on geekdad.com, Shapiro "wants the price to be under $2,500". Now it emerges that this is actually the "50% off" price for 23 days only, and the actual full price will be $4000 for the basic model? It begs the question: what happened between May and now that the price of the basic unit has doubled? What happened to the planned "$2000 laser printer"??? Or is the "50% off" just a lie to generate more initial sales, and later we'll see "new fantastic discount slashed from $4000 down to an unbelievable $2000"? I see a lot of this sales tactic in online tech products. Permanent discount prices, there's always a "deal" happening. The RRP is some mythical price that is never actually reached.

You can always order a Chinese made laser cutter which has 80% of the features and 100% of the most important ones. If you go this route, get it from a dealer in your country with a good reputation so you can get service and support.
marcosdumay 11y ago
Worst part is that if I try to buy something like this in Brazil, it'll probably get apprehended by customs as a dangerous item.

    It's Brazil... This would be a nightmare to make happen, you would need to bribe so many people to get a shipment here that your profit would be unworthy and also make you a criminal or you can run it by the lawn and never get the items or pay 100% taxes over them + their shipping costs making a machine like this cost U$5000,00
    - dfar1 11y ago
      I am Brazilian and I second this message.
  - outworlder 11y ago
    An opportunity? Let's see. There are lots of customs fees involved that are not considered taxes per-se. But let's ignore them and look at taxes: You get a 60% import tax right off the bat (this applies over the product cost, the aforementioned fees AND shipping). Then, there's ICMS, which varies by state (let's say, 12%). There's also IPI, which is variable according to the product and I'm not sure where a laser cutter would fit in. Also PIS (1.65%), COFINS (7.6%) and IOF since it probably involves currency exchange (0.38%). Speaking of that... there's the unfavorable exchange rate. Today, the real hit a high of BRL 4.23 for one USD. It was 2.50 something one year ago, and then the economy blew up. I'm not going to the trouble of trying to calculate the final price, without the importer's markup, but it will be HIGH. Good luck marketing this thing to anything other than medium businesses. And that one year from now. You'll spend like an year incorporating your company and navigating the customs law mess. There are other options, of course. Manufacturing locally would bypass a lot of taxes (and generate others). But then you could negotiate deals with local authorities in exchange for job creation and some strategic dinners. That sort of stuff. The opportunity cost of doing that is just huge and, by the time you managed all that, you'd be profitable in several other countries already. Then you'll have to deal with the crappy transportation infrastructure. Forget shipping things by train, you'll have to use trucks. Delivery estimates of 30 business days are not uncommon at all. My advice? Stay away from Brazil. Even more so this year. There's a reason investors are pulling money out of the country. Disclaimer: I'm Brazilian.

3dfan 11y ago

In the video, at about 13:40 they reveal that to print you have to use the web interface which runs "On Googles Cloud". I would not like the interface to my own printer to be "In the Google cloud". Does that mean when the company goes out of business, the printer is bricked? And right after, they admit that they plan adding paid services. Oh oh. How will thesed paid services be announced? I can imagine how. Whenever I want to print, this thing will bug me to pay for some fancy addon. And privacy? Goes right out of the window. Everything I print would go through all kinds of hands. The manufacturer of this printer, Google, my carrier and who knows who. And what about security? This is probably a full blown computer they want me to give access to my lan and internet connection. Who guarantees it gets security updates?

mlmilleratmit 11y ago
Good question, I _think_ the ideas is the exact opposite -- you're not depending on Glowforge UI to be backed by a startups servers, the software runs on google cloud instead. Pros and cons, obviously, but I think the main pro is (like a Tesla) the machine's performance and usability can be improved without you installing any new software. As far as dependencies go, google's probably the best possible choice.
- ISL 11y ago

Meanwhile the comment seems to slowly recover. Nowhere on their website they say so. I would be really pissed if I bought a printer for thousands of dollars, unpack it and then realize I cannot use it. Letting it use my internet connection and being dependant on the services of a company to use it would not be an option for me.

It's a very polished product, and the "pen" mode is a cool idea. To me, they're targeting an odd demographic, Makers who can afford expensive toys / tools, but also want a very friendly, hands-off interface. I would have expected the Maker camp to be ordering ~ $700 40-50W laser cutters from Shenzhen. I suppose the Glowforge would be pretty great in a school setting, though.

How is a 40W laser Class I, but the 45W laser is Class IV?

danshapiro 11y ago
(ceo/cofounder here) You're right - it's the passthrough. CDRH is very strict about what could count as human access. We have some clever interlocks in place around the passthrough but if an examiner can place a mirror in the interior and measure laser output above the threshold without triggering the interlock, you're Class IV.
mlmilleratmit 11y ago
This one I actually know -- biohazards depend on more than just wattage -- spot size, wavelength, pulse characteristics, etc, all go into it. I think you really compare them based on the Poynting vector. Disclosure: I'm a GF backer and am a card carrying physicist who had this question on his qualifying exam in grad school. https://www.rli.com/resources/articles/classification.aspx https://www.rli.com/resources/articles/classification.aspx
aidenn0 11y ago
You can get Class I by preventing human access, I'm guessing the Pro can't have the same interlocks for some design reason.
- mlmilleratmit 11y ago
  I think the pro is 'feed-able', wonder if that's it.
  - aidenn0 11y ago
    Yeah, I just saw that on their youtube video; the sides can remain open during operation to allow etching/cutting of materials larger than the enclosure. That means human access is possible, so therefore the class IV.

Someone1234 11y ago

I am surprised it can cut paper without causing ignition. I wonder how many of the projects shown were created using the "basic" ($2K) version and how many were produced using the pro ($4K) version? I will say their early bird prices make these compelling for small business/etsy setups. However once they go to full price, I don't know if that will remain as true. It would take a LOT of wallets to break even at a $4K buy-in for the "basic" version. PS - We live in an exciting world. Between 3D printers and these, you really can do more at home than ever before. And this type of technology is bringing tooling prices down massively even if you have it fabricated. PPS - Looking at the material costs on their page, and looking at how much these items sell for on etsy right now ($39 inc. free postage), you'd have to sell over one hundred hardback skins for a Macbook Pro just to break even (and that's ignoring many of the hidden costs of running a business, like accountant, licensing, your salary, etc).

danshapiro 11y ago
(cofounder/ceo here) I don't remember which sample items we made on which model, but everything you see is printable on the basic model. For example, the monitor stand and dollhouse don't have pieces larger than 12x20.
jay-saint 11y ago
A 100 unit break even point is incredible low. Have you read many of the write ups on product based Kickstarter campaigns. From what I have read most break even point are into the 1,000 plus units if you have to account for fabricating molds or dies. Then these mold and dies can only be used fro one project. That is the beauty of 3D printing, laser etc. You have one tool that can be used to fab hundreds of designs or product with no tooling costs.
outworlder 11y ago
> I am surprised it can cut paper without causing ignition. As a kid, I had a lot of difficulty trying to ignite paper with lenses under the sun (white notebook paper). I then gave up and used the lenses for cutting instead. So I'm not that surprised. To this day I wonder what would be the correct set of conditions that would make it easier to combust. I remember trying black paint - that only made the cutting part easier.

hamoid 11y ago

Laser cutters generate smoke (with possibly toxic particles). They have air extraction attached to them for that reason. No air extraction on this model?

hamoid 11y ago
I had missed point 12 (air filter upgrade), and non of the pictures showed an exhaust tube...
mlmilleratmit 11y ago
Take a look at the specs -- you can either vent them out a window or buy the air filter (which I'm guessing is a fancy charcoal scrubber, don't know for sure).
tomwphillips 11y ago
I came to say the same thing. My lab uses an industrial laser cutter a lot, and perspex fumes stink. We have a large extraction unit to capture the fumes. Filters only capture a limited range of compounds too. Important to always check whether the filter can handle the material before cutting.

littletinman 11y ago

(ceo/cofounder here) There are lots of folks doing bathymetric maps with lasers; I don't know who was first to it. We generated ours from scratch from NOAA data, but owe them (or whoever did it first) a debt of inspiration.
smackfu 11y ago
The problem with making something out of public domain maps using technology is that it's very easy for someone else to copy it pretty effortlessly.

chromaton 11y ago

This looks like a decent laser but I thought I'd post a few thoughts about this package which might give a potential buyer pause. First, the main unique feature I see is the built in camera which apparently gives you a preview of cut/engraved finished part on your computer screen with the material as it's positioned inside the machine. This also (apparently, it's not clear), allows you to correct for misaligned material inside the machine. These are nice features, but it's perfectly possible to cut and engrave without them. One big problem with operating this inside your home is the fumes. Now, they do mention that the base unit needs to be vented to the outside. What this means is that your neighbors (and you, if the wind is right) will have to smell the exhaust from this machine. It's not a nice smell if you're cutting acrylic. Though I personally got used to the scent of vaporized acrylic over time, your neighbors might not be so inclined. So they also offer a $500 add-on ($1000 regular price) to filter the air so you can exhaust inside. The add on is smaller than the already small laser cutter. This is quite a feat and I would really like to know how they got it to work. You see, the fumes/smoke from a laser cutter can really clog up a particulate filter pretty quickly. Wood produces wood smoke, and acrylic vapor is quite sticky when it settles. So you have to have a powerful pump to draw the fumes through the filter. Then you need a good amount of activated charcoal to get rid of the smelly stuff. If you look at the professional model air filters, they're $2000+ and you have to buy filters and media regularly. Laser cutters get messy inside, so if you buy one, be prepared to clean it out regularly to keep the optical and mechanical components clean. Problems with operation can START A FIRE, so be prepared to watch the machine 100% of the time while it's cutting.

noobermin 11y ago
Every issue you mentioned apart from the terrible fumes are problems that already exist in one's home with cooking in your own home, and people, seeing the convenience of cooking in their homes, have adapted to it. Regarding fumes actually, the smell from my neighbor's cooking isn't always to my liking either, but, perhaps, burnt plastic might be worse and equally undesirable to all people.
- elecengin 11y ago
  I think one thing that was not clear are the fumes are extremely toxic. Rarely do you cook where the fumes could make you go unconscious or cause long term health effects.

I have a 40W hobbyist laser cutter. It's fun, and a great tool for various projects, like making board games[1,2]. That said, sometimes materials inside the machine catch fire, and sometimes the beam reflects or dwells on a section of the metal enclosure. It's interesting that they've chosen to make the entire (?) enclosure out of plastic, itself a combustible material. I get why they went with plastic (cheaper to fabricate once you have the molds, lighter to ship, perhaps better dimensional accuracy than cheap sheet metal), but it does not seem particularly safe. The also seem to gloss over the need to ventilate the machine. Plastic fumes are nasty to breathe, glue-bonded wood (think thin plywood) can release formaldehyde fumes, leather may be dyed with heavy metals. What the laser doesn't cause to combust cleanly, it vaporizes. You don't want those emissions in your house of office, and you want them vented away from the optical components as quickly as possible so there is no deposition onto mirror or lens surfaces. Another benefit of metal enclosures is shielding the power supplies of these things. High-voltage laser power supplies are noisy, and when you PWM them, they can cause quite a bit of interference. Metal enclosures at least help to attenuate RF emissions. The "macro camera" is a clever addition for closed-loop optical control (if it is being used for that). Reminds me of attaching an optical mouse sensor the the lens sled. 1. https://igcdn-photos-b-a.akamaihd.net/hphotos-ak-xfp1/t51.2885-15/e15/10549813_673074649438401_1078246007_n.jpg https://igcdn-photos-b-a.akamaihd.net/hphotos-ak-xfp1/t51.28... 2.

What unit do you have? I've been thinking about getting one.
- tomkinstinch 11y ago
  I have an older one from Full Spectrum[1], from when they were adding their own control PCBs to generic units imported from China. The newer ones they have look nicer. There are a few other options on the market now, so it's probably worth shopping around. Larger cutting areas are nice, if for no other reason than that they limit the number of cuts you have to make on raw materials to get them to fit into the machine. I made my own recirculating laser tube cooler using desktop PC water cooling components[2]. Beyond board games, they're useful for making tools for other projects. Need a drill guide with precise spacing? No problem, cut one out on the laser cutter. Need to prototype a coarse-pitch circuit board but don't want to wait for OSHPark or pay for a quick-turn fab? Ablate black paint off a Cu-clad board and chemical etch. Want to de-cap IC packages? You can, with some care. Interested in prototyping microfluidic structures? Sandwich some cut sheets of double-sided tape between acrylic sheet. Need to make a quick enclosure for a project? Design a box [3,4]. Cut the sides out of acrylic, and bond with dichloromethane (with ventilation!). It's great for making fixture components for things like robotics since you an easily include holes for machine screws. They're also fun for cutting leather, cloth, etching aluminum laptops, making gifts, etc. If you don't have access to nice commercial CAD software, DraftSight is a free AutoCAD clone that works fine for 2D drawings[5]. Otherwise, Inkscape works well for 2D, and for 3D, Rhino[6] has an affordable educational license that permits commercial use. 1. https://fslaser.com/Products/Lasers https://fslaser.com/Products/Lasers 2. https://github.com/tomkinsc/Laser-Cooler https://github.com/tomkinsc/Laser-Cooler 3. http://boxmaker.connectionlab.org/ http://boxmaker.connectionlab.org/ 4. http://www.makercase.com/ http://www.makercase.com/ 5. http://www.3ds.com/products-services/draftsight-cad-software/free-download/ http://www.3ds.com/products-services/draftsight-cad-software... 6. https://www.rhino3d.com/ https://www.rhino3d.com/

  The TL;DR is that she was part of creating a toxic environment within the company, shipped a product they knew was defective (Makerbot fifth generation), misled the shareholders (of Stratasys) and ultimately cost Stratasys hundreds of millions.

That's a nice unit, and adding a camera is a big step forward. More CNC machines should have cameras to aid in alignment. I'd really like to have a camera with high magnification on a CNC mill, rigidly mounted a known distance from the spindle, and cross-hairs on the monitor.

I've worked with Laser cutters and, unless they have fixed things, you really don't want to be cutting items--especially paper and cardboard--without industrial "shop" ventilation. And many times I've set my work on fire.

mindo 11y ago

Looks like a great toy until you go through comments here. Honestly would have bought this for my woman, since she's into crafts and stuff, but cloud-only cutting/engraving, comments on fumes and filters + dealing with customs (if they even shipping int) quickly changed my mind. I've seen laser engravers on kickstarter before, hope to see more machines that do not require clouds to cut/etch a damn thing.

llamataboot 11y ago
I really feel like if there are enough of these out there and the company somehow decides to brick all of them (not that likely IMHO) that someone will be able to come up with an open source solution for controlling it. I'd like to know what their privacy policy is but I'm not particularly worried about it becoming a multi-thousand dollar hunk of plastic. I do wonder why the pre-order price is SO much cheaper than the actual price. At pre-order it's a still. At regular price it's kinda a bit meh.
- harryjo 11y ago
  They want to motivate interested buyers to pre-order. The "actual" price is FUD.
harryjo 11y ago
These aren't really for home use. They are for Maker spaces and workshops and schools. Your partner should bring her design to a local workshop to cut, unless she wants to open the local workshop.

  It's easy to say bring the design "to local workshop to cut", they are available in US/CA/Europe, but finding one asia or africa, or even smaller european city is hard if not impossible.

This is going to be epic for schools and print-shops. I think only hardcore enthusiasts will want a home-home version of this tech, but I've spent enough time with paper-cutters and cutting out letter shapes that this is really cool. Also, the boardgame industry can prototype cards much better with this - printing out Catan-like hex-tiles and the like.

alexisnorman 11y ago

I can't count the number of times a fire has started in my university woodshop because of smoldering debris and general lack of safety knowledge with laser cutters. I would assume this is something to be aware of with the Glowforge but I don't see any safety information on your webpage. Is this something to still worry about with 40W and 45W lasers?

Is there some strategy for customers once the cloud servers shut down? The company doesn't have to go out of business - perhaps five years have passed and you've moved on to more awesome models. While your business might feel that customers should upgrade to the newest, it's not great that they would be forced to. For instance, when Steam was first released Valve promised that should the authentication servers go down, they would ensure that the games would stay functional without them. This was an important point that contributed to its success.

cwkoss 11y ago
Open sourcing local backup server software would be a cool move.

Can this device cut metals and if so which ones and of what thickness?

mchannon 11y ago
A 40W CO2 laser will not cut metals, period. Save yourself the wait and spend $395 on eBay to get a much more sturdy version shipped to your door. It's not perfect but at that price, imperfection is forgivable.

paulmd 11y ago

This is a pretty neat product. I especially like the continuous-feed idea. I'd really like to do stuff that involves stainless. What would be the cheapest option capable of doing some reasonable sheet stainess? My wallet is cringing at the mere concept, but maybe I could talk a local hackerspace into doing it or something. I've been meaning to build a CNC mini-mill for a while. I think that seems like a more practical option for stuff that doesn't require intricate cuts. And definitely more affordable.

theatrus2 11y ago
A CO2 laser will not cut stainless - it won't even mark steel unless you coat it with a special ceramic. You're looking at a very very large fiber / YAG laser to cut it. A low power YAG laser can engrave steel - commercially these start at about $30k
- krasin 11y ago
  Technically, the statement "CO2 laser will not cut stainless steel" is not accurate. Stainless steel is commonly cut by 500W-5kW CO2 lasers, see: https://www.coherent.com/Applications/index.cfm?fuseaction=forms.AppLevel2&AppLevel2ID=62 https://www.coherent.com/Applications/index.cfm?fuseaction=f... https://vimeo.com/106264555 https://vimeo.com/106264555 But it's true that sub-100W CO2 lasers are not even remotely capable of cutting steel.
IshKebab 11y ago
For sheet stainless you're probably best paying someone to water-jet cut it. Laser cutters that can cut metal are way way way out of the price range of normal people. Also you can't really mill sheet metal. If you want to do something cool and home-made you could probably hook up an electric nibbler to an X-Y stage.

$954 shipping cost to UK. Isn't it a bit high? Also UK regulations says I need to be supervised to use a class 4 laser since I can point it to somewhere I shouldn't. I wonder if that's still valid for an enclosed product.

ape4 11y ago

Whats the purpose of the big button the device? I would have thought starting a print from your computer would turn it on.

oasisbob 11y ago
It's the "the cloud can't activate a 40W cutting laser in your home by itself" button. At least that's how it's explained more-or-less in one of the videos. Makes sense to ensure that the operator is in front of the machine and has everything properly loaded before firing the laser. Who knows how much of that is really intended as a security process...

desireco42 11y ago

It looks really amazing, but until it gets shipped and reviewed, it is just a video. I don't doubt they have prototypes nor I doubt their ability to ship, but once you do, then it is a real product.

newmotors 11y ago

@danshapiro Questions : 1) Why could you not have done this with a quad core i7 box running ubuntu? The amount of time it will take to ship information from my box to google cloud is longer than what can be done on my box. What exact monetization strategy made you keep software/data in the cloud? 2) Any ETA on when the machines will start shipping? Assuming you now know how many people ordered already.

xrjn 11y ago

I spend a lot of time playing with a laser cutter (120w generic from China). A lot of the things that they talk about are quite cool, but I think that they do not show all the other parts that also require time and effort - although I do imagine that one of their value propositions is that they remove and/or simplify a lot of the processes and their complexities. One of the biggest issues I currently have is to generate a file that the laser cutter will like - it has to be a dxf with no sub layers or any linked files, or a old illustrator file (.ai version 8). Each "settings layer" has to have it's own distinct color, and sometimes if the colors are too close, they get merged into one. It can also be difficult to set the correct distance between the things that you want to engrave and the things that you want to cut - say you want to engrave a round logo on a round beer coaster: getting this perfect would take a lot of tweaking, as there are minor (yet visible) gaps and mis-alignments. Next, to get the laser to cut properly also takes some tweaking. It's almost impossible to get a repeatable cut, since there are so many different factors that you need to take into play: the location of the item you're cutting on the bed, the temperature of the laser, the thickness and quality of your material, the accuracy of the auto-focus, and the settings themselves. If we look at the location for example, there is a huge difference between the top left corner - where the laser mirror is - and the bottom right corner. On one side your material will catch fire, on the other, it will only cut half way through. The material is also an important factor - if the material is even 0.2mm thicker on the top compared to the bottom (especially true for acrylic), then the laser will go through on one side, and won't go through on the other. For wood, tiny differences in it's quality can have a significant impact on the cut and especially on any engraving you do. With wood and similar, easily smudged materials, you also have this sort of 'caramelisation' after you cut and engrave - the degree of this effect depends on whether you used the right power or not (for which you also have to take into account the location, temperature, material quality,...). If you try to clean it off by hand or with a dry tissue, you will smudge it further and it will be difficult to remove. Instead, you have to painstakingly clean every piece you cut with an alcohol soaked cloth, which will remove most of these smudges - however it won't remove any burn marks. As per the burn marks, you get a lot more of them when you use a honeycomb bed compared to one which has a number of thin pieces of metal that stretch across with a few cm interval. The glowforge laser has this honeycomb bed, so expect your wood, cardboard and paper cutouts to have some of these burn marks if you don't pay very close attention to the power/speed of the cut. With plastic, getting a cleaner cut is a bit easier, but the fumes are horrendous. Also, if you don't cut through the whole thickness of the plastic the first time, and do another pass, the edges which you cut will have these 'micro-cracks' that dont' look very professional. Similarly, if you cut with too much power, your plastic edges will just melt and look quite bad. However, an advantage with plastic cutting is that you can clean it without too much difficulty, if you use sufficient alcohol you can get most burn marks away. Engraving looks really nice when done with a laser cutting, but it does take some time until you figure out the correct settings for each material. I particularly love engraved plastic and wood, the result (especially from genuine, extruded plexiglass) is beautiful and vey professional. A local public figure has had a picture of him holding a laser-engraved logo that I made him as his profile picture. Personally, I made some laser cut business cards, and they have absolutely blown away a lot of people - one person even told me that he stuck it to his wall for inspiration. I've also worked on laser cut tags/tokens that I give out as a promotional gift to people, and then they can use it as a fidelity card when they order things through my startup. I'm still working on perfecting these tags, but they required a lot of testing (over 30 different attempts just to get the QR code to engrave in a readable way), and I still haven't been able to generate them through software (right now they have to be put into illustrator before exporting them to the laser cutter). Lastly, engraving paper will likely incredibly difficult. On their page they have a sheet of paper that they engraved - I want to know how many attempts it took them before they got it to work - especially since the paper gets very easily caramelised. Maybe they had to use a special coating or used yellow/blue painters tape? Despite all of this, laser cutters are extremely cool. The one we have cost $4000, and people have done lots of amazing things with it. Nowadays, you can get a 40w laser from ebay or aliexpress for a few hundred dollars, but do expect to spend weeks figuring out how to use it. The Glowforge looks like a pretty cool idea, however I don't know if they'll be able to survive at this price point + with the technology being at the state it is today. Their software (minus the part where it's cloud based), looks really powerful and very useful.

So in a followup, Glowforge offered to release the firmware of this 3d printer as GPL. That is a ballsy and incredibly great move. It also helps negate the issues of their cloud service going away, I have an expensive paperweight issue. See: http://glowforge.com/gpl-licensed-open-source-firmware-for-glowforge/ http://glowforge.com/gpl-licensed-open-source-firmware-for-g...

Pxtl 11y ago
The thing is that their firmware is ultra-lightweight. One of the things they're proud of is that the firmware is extremely thin and basically shunts control signals directly from the cloud service. The cloud service does everything. The expensive paperweight issue still stands.
- lairdpop 11y ago
  I am not sure that this would be the case. If all the firmware has to do is process G code, that's oh well understood problem, and runs on Arduino's, and whatever is grilling this printer has to be at least as powerful as we oh well understood problem, and runs on Arduino's, and whatever is grilling this printer has to be at least as powerful as Arduino, and he clearly has four more storage since it can buffer print streams coming across the Internet which is a lot harder then coming in local connection. The only limitation I see is that the device does not have a USB port, which means that even if you're printing off-line you're going through Wi-Fi. If the company went under, I'm wondering if the answer wouldn't be to reverse engineer enough of the server-side to print, and run a copy of that locally, without having to change the printer's firmware.

jps8 11y ago

@danshapiro - Thanks for giving a fantastic resolution to the issue of the cloud software. I think that was a big hang up for many of us. Can you expand on the benefits of the Pro model? The usefulness of the included air filter and pass through slots have been explained on your site, but the laser and cooling upgrade aren't really ever discussed. 5W more power doesn't seem like very much of an upgrade (12.5% more power for 60% more cost). What does the Pro model's upgraded laser and cooling specs mean in terms of "usefulness": cuttable material thickness, cutting times, duty cycle, etc? Also, what's the expected life span of the charcoal filters, HEPA filters, laser tube, and any other consumables? Are replacements for these available only through Glowforge, or are they industry standard / Over The Counter parts?

diyseguy 11y ago

It looks like vaporware to me. What gives me pause is the sneaky way they present it as if it were a KickStarter project, but it's not. So all those people shelling out for the early release are not protected if they close up shop and disappear it seems to me. So many glowing promises, but will they be able to follow through on all of them? I dunno. I am skeptical. (I hope they do though, I seriously want this to be real).

exodust 11y ago

Disappointed in the pricing tactics, and doubt the "50% off" is anything but typical sales bull. Back in Feb in an interview with Shapiro in the NYT it was stated "desktop laser cutter that it plans to sell for around $2,000". No mention of this being a special 50% off price. And in May this year on geekdad.com, Shapiro "wants the price to be under $2,500". Now it emerges that this is actually the "50% off" price for 23 days only, and the actual full price will be $4000 for the basic model? It begs the question: what happened between May and now that the price of the basic unit has doubled? What happened to the planned "$2000 laser printer"??? Or is the "50% off" just a lie to generate more initial sales, and later we'll see "new fantastic discount slashed from $4000 down to an unbelievable $2000"? I see a lot of this sales tactic in online tech products. Permanent discount prices, there's always a "deal" happening. The RRP is some mythical price that is never actually reached.
