California AB 2047 makes 3D printers off-limits to students, educators, business
- dgellow 3mo agoIf that becomes current law I don’t want to ever hear about Europe being over-regulated compared to the US…
- micromacrofoot 3mo agoRegulatory speaking, California is America's Europe
- kogasa240p 3mo agoWithout the robust train system, but that is changing slowly.
- jltsiren 3mo agoEurope favors comprehensive regulation, with laws or directives dealing with families of related issues. California does regulation in a very American way, with individual bills targeting specific issues. It just does more of that than the average state.

- dimitrios1 3mo agoand I would imagine close to 100% of the US 3d printing nerds that live there have the means to easily move to another state and continue their 3d printing nerdom. There is a reason why California is leading the nation in migration out of the state.

- waffletower 3mo agoDescribing California as "the Europe of the United States" ignores its essential narcissism -- defining California in terms of Europe would be met with contemptuous pashaws, even if the balkanized ethnic enclaves found there, at a scale larger than anywhere in the U.S. -- not even New York, resemble Europe. The Asian communities will also wonder if you can find Vietnam on a map -- would guess you think it is in the Mediterranean.
- vor_ 3mo agoThere are several snarky knee-jerk reactions in the comments here, but state assemblies pass things all the time that ultimately fail to pass or get vetoed. Now the public will debate it, contact their state senators to give their opinions...it's all part of the process.
- harshreality 3mo agoA law like this just passed in New York State. If this fails it'll be because the tech industry expresses disapproval too loudly to ignore. The legislators don't care about the underlying criticism. Almost no legislators have ever used a 3d printer or written any software, beyond maybe simple assigned programs if they had a required intro-to-programming course. Few are "tech" people. The rest don't understand this technology, or any technology really, beyond it being a black box for specific purposes. They see 3d printing and plastic guns and think something must be done, because the 3d printing black boxes are producing dangerous weapons.
- jasonfarnon 3mo agoAre these laws already on the books places like Europe, Japan with strict gun control laws?
- elzbardico 3mo agoGood laws for gun control probably are enough to cover also 3D printed guns.
- int_19h 3mo agoThe problem, as far as they are concerned, is enforcement. The law can say that X is illegal and ban selling it, but if you can 3D-print it, and its use is already illegal either way, then the law is moot. Note that this isn't really limited to guns either. I foresee a similar moral panic wrt 3D printing "killer drones" (i.e. parts that allow one to attach explosive to a drone) and software that allows you to circumvent various restrictions on drone firmware. All it'll take is one high profile attack using a drone...

- Legend2440 3mo agoThe California legislature has a history of passing stupid stuff that later gets vetoed by Newsom. They tried to ban self-driving trucks last year.
- calgoo 3mo agoThat does not sound stupid, but safe? I giant truck that has no chance of stopping, controlled by a computer? Just build railways and then there are no issues, no fancy AI to control them.
- cortesoft 3mo agoA giant truck that has no chance of stopping, controlled by a human is even more dangerous, but we don't outlaw those.
- vor_ 3mo agoHow did you determine that it's even more dangerous?

- NDlurker 3mo agoI can't tell if this is a joke or a serious question.
- vlian2088 3mo agoI'm seriously questioning the absurdity of banning something that remains available a 15-minute drive away, behind a purely informal border. I don't think, for example, that recent abortion bans had reduced the number of abortions in their respective states to zero.
- function_seven 3mo ago1) For the vast majority of Californians, the nearest state border is 3-5 hours away. 2) those abortion bans have definitely reduced the number of abortions. Not zero, but that's a silly goal for any ban. Obviously the law is stupid. But states passing their own regulations isn't on its face.
- vlian2088 3mo ago>those abortion bans have definitely reduced the number of abortions. Not zero, but that's a silly goal for any ban. really? what percentage of Americans can't afford a bus ticket to the nearest city in an adjacent state?
- NDlurker 3mo agoA lot of rural areas don't have good transit. Even if they do, it's hours round trip. Here's an example. North Dakota has an abortion ban. Someone in Minot would need to travel almost 5 hours to Moorhead, MN or almost 7 hours to Billings, MT. Now that's not any different really than before the ban, because the only clinic in ND that provided abortions was across the river from Moorhead in Fargo. But what if that clinic in Moorhead closes? Or what if Montana bans abortion? It's banned in South Dakota, so people out in western ND, SD, or anywhere in Montana are going to have to travel even further. There are many small communities around here with no bus lines or trains coming through so they're stuck if they don't have a good car.
- androiddrew 3mo agoYeah you. Better get your printer air gapped because they are going to brick it in the name of getting re-elected
- mc32 3mo agoWhy does California since Arnold left office feel the need to regulate above the average other states regulate? [in fairness gov Brown would veto some of the crazier ideas that arrived at his desk] Why do the pols feel like they have to pick fights in so many places? I doubt there’s a majority of voters who want this.
- Gigachad 3mo agoThis feels exactly like a feels good general public appeal law though. The average person doesn’t know or care much about 3D printers and is horrified by the level of gun violence in America and wants to see something done.
- LNSY 3mo agoWhich is sad, considering that we have the lowest violent crime rate since the 1950's. https://ourworldindata.org/us-crime-rates https://ourworldindata.org/us-crime-rates
- ConanRus 3mo ago[dead]
- arjie 3mo agoWell, from the point of view of Californian politicians, was it their anti-balance-billing AB72 that was over-regulation before No Surprises Act? Or the CCPA? Or the Auto-Renewal Law? And looking back even farther: was it CalOPPA that was overreach requiring privacy policies? Paid family leave and sick leave? Some made life hard for Californians like the CARB gasoline blend requirement but I think if you proposed removing any of those laws you'd find yourself downvoted here and called a corporate bootlicker on Reddit - which is not a poll of all people but should give you an idea of the fact that they're not unpopular.

- smt88 3mo agoFor a long time, you couldn’t buy “strike anywhere” matches because they could be used in producing meth.
- philipkglass 3mo agoIt's the striker strip that can be used in producing meth. The strip contains red phosphorus. Strike anywhere matches are the only kind that don't need a special strip. The strike anywhere kind were probably restricted due to their sensitivity to shock and friction which makes them more useful and more dangerous than safety matches.
- black6 3mo agoLoading a tennis ball full of the heads of strike anywhere matches is a core childhood memory.
- bri3d 3mo agoI am not aware of this being a regulatory matter in any state, California included. Retailers choose not to carry them because they are expensive to ship due to their hazardous materials classification and an attractive theft / crime target due to their (inaccurate) drug association, but it hasn’t led to any blanket regulation at any state level that I know of. I do think they’re banned from workplaces in California though, but that’s because they’re dangerous, not because of meth.

- trhway 3mo agoAs the latest affair shown, US is falling behind in drone tech. Now another key modern tech is going to be similarly outlawed. Note that in particular banning of 3d printing severely decreases chances for bringing back manufacturing - high labor and other costs makes domestic manufacturing feasible only when it is highly automated and highly customizable.
- TacticalCoder 3mo ago> As the latest affair shown, US is falling behind in drone tech. Now another key modern tech is going to be similarly outlawed. My bet is the US militaro-industrial complex is busy preparing juicy contracts to sell shitload of drones and drones-related tech to the US government now that they understood that drones in warfare were a thing (Ukraine vs Russia showed it and Iran-vs-the-world showed it too). The US has something like 12 tech companies in the top 20 biggest companies by market cap in the world: do you really think the US is "falling behind in drone tech" because a country that has never invented anything (besides mass killings of their own citizens) since religious extremists took over managed to fly a few low-tech drones into US military assets? That a country bent on violence (including towards its own citizens) where pick-up trucks armed with .50 cal, AK47s and explosive are the norm can slap explosive on DJI drones is resourceful but I wouldn't exactly call it "passing ahead in drone tech". I don't gamble but I'd make an exception and bet big that the US is going to end up right next to China, at the very top, when it comes to drone tech. While I fully expect the EU to fall behind in drone tech.
- trhway 3mo ago> a country that has never invented anything … managed to fly a few low-tech drones into US military assets And de-facto won the war as a result. That is reality. That is the power of that weaponry, and that is the falling behind. And that after 4 years of such a war in Ukraine. I agree it is very possible that US would be at some point able to build up those capabilities. Though, limited to established players, it most probably would be very expensive and thus go against the key feature - cheapness - which in itself allows for the other key feature- mass scale of the drone weapons.
- guelo 3mo agoPhotocopiers and printers have included anti-counterfeiting tech for decades, so there is precedent for this kind of thing.

- mvdtnz 3mo agoUntil America bans actual guns I don't want to hear about the "growing problem" of 3D printed guns.
- greenavocado 3mo agoThe establishment is desperate to create/maintain moats to maintain hegemony over society
- bluescrn 3mo agoYeah, if it was the UK cracking down it'd make more sense, but IIRC the US already has more guns than people. And in places where guns are tightly regulated, most people couldn't get hold of ammo even if they did build a printed gun, so it's not a big problem. (And the bad guys just use kitchen knives)
- gmueckl 3mo agoBut money counterfeiting is a different proposition: the printer is blocking exactly known patterns found on real currency. In fact, many bill designs incorporate patterns that are easily machine detectable for this purpose. Blocking the printing of parts of mechanisms is a completely different beast, because the functionality is only discernible after final assembly of the individual parts, which can be shaped in a variety of ways. Most of these parts are unique to guns or at least usable in other kinds of designs. E.g. the same trigger lever design could be used for a ghost gun or a nerf gun or a water pistol. So where would yiu draw the line of all the classifier sees is G code that combines support structures, the actual surfaces and infill of some arbitrary collection of parts? I'm against guns in generally, but this classification problem seems particularly ill posed and I don't want it to result in tamper-resistant printers stopping people from tinkering and taking the fun out of printing. The US should just outlaw the casual carrying of guns of individuals in public. That's not a violation of the second amendment.
- umvi 3mo ago> The required technology is not possible - 3D printers read code, not intent; they cannot tell what a shape is for. "Anthropic announces Project Disarm, a new model designed for 3d printer manufacturers to quickly infer whether the intent of an stl file is a weapon. The printer first submits the job to the cloud, and only after it's approved will it print." Not that I want this future, just that I can imagine it.
- ex-aws-dude 3mo agoKnowing how governments do this stuff its going to be something lazy/easy to bypass like a list of stl files/hashes that are banned
- fc417fc802 3mo agoTo mitigate that, and as a token acknowledgement to privacy concerns, OpenMappleSoft will introduce a device side fuzzy hashing scheme whose output it turns out you can reverse to recover the original weapon schematics.
- mc32 3mo agoYou missed the step where a DMV-clone of a state bureaucracy reviews the LLMs output before nixing the request a few weeks after the LLMs result.
- cucumber3732842 3mo agoI was thinking more along the lines of you pay someone with a state license an obscene amount of money to sign a piece of paper that basically says it's fine while also having no liability for being wrong. And then the DMV say that's not good enough and you have to go around again and pay them for more. This is basically how civil engineering works for every project type that doesn't involve a pitched and (specifically "and" not "or") high stakes battle with gravity where you'd want to hire one on pure merit.
- jchw 3mo agoBased on the fact that Claude Opus 4.8 decided I needed a cybersecurity exemption to debug a stupid pure virtual call bug (basically virtual method called inside of destructor) that I had already found, oh boy, I sure would love to have my 3D prints analyzed by Anthropic safe guards. We should also ensure that nothing shaped like a dildo can be printed without scanning our face and genitalia and keeping it on file with Persona while we're at it. I'm not mad at you for suggesting this, you're right, I'm just generally aimlessly angry and ready for this world to burn.
- cortesoft 3mo agoThis is such a dumb law. We have millions of guns in the state, 3D printed guns are never going to be more than a blip in the statistics for gun deaths.

- ex-aws-dude 3mo agoAlso don't they require real metal parts anyway?
- nozzlegear 3mo agoLawful gun use means the guns must be registered and users need to be licensed and go through background checks. Presumably part of the concern with 3d printed guns is that anybody can print them without going through that registration, licensing and background check process.
- deckar01 3mo agoI tried to photo copy a dollar bill when I was a kid on a dinky inkjet printer. It printed half way then spit out something about counterfeit prevention. I scanned the bill, printed the top half, fed the paper back in, and printed the bottom half. This can only actually stop the completely unmotivated.

Windows and MacOS constantly sends the serial-numbers of your connected devices back to the mothership. [1][2] 3. So when you print out a flyer that somehow annoys the regime, they read out the serial number, then call a buddy at Microsoft/Apple. 4.

- yieldcrv 3mo agoThis doesn’t have to be unconstitutional, just regulate the intermediary in such a way that it forces the behaviors you are trying to regulate directly In this case you can say “You need a license to do this activity” [adds all the requirements in the bill to the licensing authority] “Unlicensed activity is forbidden” so now you can get your tiny LLMs added to 3D printers so that license holders can operate again, without specifically mandating unworkable technology or getting a freedom of expression challenge from the manufacturers you just invented court standing for This works under every governance system

- mothballed 3mo agoThey're pretty damn reliable if you either use a hybrid model (FGC-9) where the barrel is "explosion proof pipe" from china that is then electrically machined (easy with 3d printed mandrel) to form a nice rifled barrel. Or you just 3d print the "receiver" for something like an Ar-15, which isn't load bearing. If you use the right materials and the beefier designs it will lats hundreds to thousands of rounds. The rest of the parts can be bought through the mails unregulated.

- deleted 3mo ago[deleted]
- bluescrn 3mo agoIn the US I believe there's many metal 'spare parts' for guns available, including the barrel, so don't need to print the whole thing. So they're usually not talking about entirely printed guns. A pure plastic gun seems more likely to blow the users hand off than hit their target. Especially if just downloaded and printed in PLA on default settings (few walls, sparse infill...)
- LorenPechtel 3mo agoThis. Guns contain many wear items. So what the ATF does is take an essential part not substantially influenced by wear and declare it to be the gun. Trade in anything that sufficiently resembles this part is treated as trade in guns. Other parts are not considered guns, they're just pieces of metal or plastic. Then there are the parts that you're not supposed to have. But is that an oil filter or a silencer? When it's on the gun it's obvious, when it's listed on a website as an oil filter...
- giantg2 3mo agoNY is pushing the same sort of stuff. The question to ask is how many people are actually being killed with 3D printed weapons? I don't have that info, but I would guess they are statistical outliers and would have been replaced by other homemade weapons if not available. Politicians love to "fix" problems that aren't really problems in the first place.
- LorenPechtel 3mo agoThe problem is there is a lot of garbage about it. Ghost guns are a real issue, but ghost guns are not 3D printed guns. 3D printed is a very niche case. They're only good for one shot ever, they are not reliable even for that. And they're bulky. The one thing they do is make it much harder for a metal detector to find them. Ghost guns made by CNC milling equipment are nearly identical to what you would buy from the manufacturer, except they do not have a serial number and you won't have the background check for a firearms purchase. But politicians are reacting to the ghost guns by going after the printed guns.
- PhotonHunter 3mo agoAnd a lot of what gets reported as ghost guns in the press aren’t 3d printed, they’re commercially-made serialized firearms that have had the serial number obliterated.
- wl 3mo agoThere are plenty of 3D printed guns that are good for more than one shot. The classic examples are 3D printed Glock-style frames and AR-15 lower receivers. As far as US gun laws are concerned, those parts are the firearm and the rest of the parts are uncontrolled. So you print those, buy barrels, triggers, magazines, etc to finish the build and voila, ghost gun.
- LorenPechtel 3mo agoYou're making exactly the mistake I'm pointing out! You do not print a lower receiver compatible with standard parts. The threat is a CNC milling machine cutting one from metal. Ghost gun = key part made by sources other than a legal firearms manufacturer. Typically, this means CNC milling. Printed guns are ghost guns, but the vast majority of ghost guns are not printed guns. Printing plastic has a very hard time confining the gunpowder. It's possible to print metal, but it's sintered (not nearly as strong) and the printers are still way beyond the home level.

It seems more precise to say that 3D printers sold/transferred in California would need built-in anti-firearm-printing controls? I don't see how this directly bans students/teachers/businesses from owning 3d printers, which is what the title seems to say.
- SpicyLemonZest 3mo agoIt does not. The gun lobby routinely lies about California regulations to try and get their way. They're on year 13 of boycotting the California handgun market, for example; new handgun models in the state are required to adopt microstamping technology, but firearms manufacturers are ideologically opposed to this technology, so they falsely claim that it doesn't exist.
- everforward 3mo agoThey don’t claim it doesn’t exist, they claim it bears a cost significant to the overall cost of the firearm and is unlikely to meaningfully accomplish its stated goals. Ie prices will go up by 10% or whatever for basically nothing. It’s a useless place to put an identifier. It can be filed off easily, and checking whether it’s present involves a microscope and/or disassembling the firearm (depending on the gun and firing pin setup). You can even just straight up replace it with hand tools at the range. More insidiously, if this passes, you’ll probably be able to buy firing pins that are stamped with someone else’s identifier. I have little doubt a market will spring up for falsely marked firing pins. Or go super low tech and just throw a brass catcher on the receiver to catch the shells. In a pinch, duct tape and a shopping bag will prevent leaving brass behind. This is just a money grab by the folks that invented the tech. We don’t even do a good job of keeping stuff like select fire switches for Glocks off Facebook, this is unlikely to do anything but raise the base price of a gun.
- SpicyLemonZest 3mo agoThey do claim it doesn't exist. It's not an argument they emphasize in their public messaging, presumably because it's such obvious nonsense, but it's one of their core arguments in their lawsuit challenging all California handgun restrictions (https://storage.courtlistener.com/recap/gov.uscourts.cacd.858747/gov.uscourts.cacd.858747.1.0.pdf https://storage.courtlistener.com/recap/gov.uscourts.cacd.85...). "Microstamping technology does not actually exist in any commercially available application on a handgun" (p. 11), and therefore it's the California law requiring it rather than manufacturers refusing to implement it that's depriving California consumers of access to modern handguns.

- mbgerring 3mo agoIn general I agree with the 3D printing and open source community that bills like these are bad ideas. However, I want to ask this question in the spirit of helping craft better arguments: Given that it is extremely well known that most commercial printers will refuse to print anything that looks like counterfeit currency, why is this considered technically unworkable? I agree that compliance would be onerous, but that's different from insisting that it's not possible.
- kersplody 3mo ago[flagged]
- anonymous_user9 3mo ago> commercial printers will refuse to print anything that looks like counterfeit currency They will refuse to print images that contain the EURion constellation, a cluster of points with specific distances between them. (https://en.wikipedia.org/wiki/EURion_constellation https://en.wikipedia.org/wiki/EURion_constellation) More generally, "Does this image represent US currency?" and "Does this 3D mesh represent a dangerous gun part?" are different kinds of questions. Checking if an image is US currency is simple. Not only can an image similarity hash be used, but the design of the currency can be changed to make checking easier. The checking program just has to run a textbook algorithm and compare the result with a handful of hashes (we only have a few denominations of bills). We can be confident that the checking program will always see substantial portions of the bill, so it can always see the pattern. If someone chopped the bill into tiny pieces, it would look fake when glued together. Looking like a real bill is the thing we want to control, and that's something we can reliably measure with simple algorithms. Checking if a 3D shape is a gun part is an unsolvable problem. (It would be equivalent to making a program that can detect hidden "subversive" meanings in text.) The checker would have to understand how the piece could operate in the hands of a skilled person. Parts could be printed in multiple pieces, or have material removed after printing, so it'd have to anticipate all possible post-processing steps. Even if the problem is limited to "match against these known gun part hashes", gun parts are not defined by their overall appearance. The files can be mutated until they no longer trip the detector, yet can be easily post-processed into functional components. (Also, a similarity hash for 3D toolpaths may not exist.) (Such a hashing regime would be useless to stop "3D-printed guns" as a concept, because the design could be changed to not match the hash at all, without post-processing.)

- narrator 3mo agoThis legislation seems to come out of nowhere and get rubber stamped. Who even came up with this, and why?
- rcbdev 3mo agoThe future will belong to China. The U.S. has fallen. Articles like this are just further proof.
- stockerta 3mo agoI never understood this hysteria about possible 3D printed guns in america where every fucking idiot can get a firearm. If this would be where I live (an EU member country) were getting a gun licence needs a very good reason is hard to get (thank god) and the police can enforce that you keep your gun locked away and such, I would understand that there would be a law like this. But in the US?
