California’s new bill requires DOJ-approved 3D printers that report on themselves targeting general-purpose machines.

Assembly Member Bauer-Kahan introduced AB-2047, the “California Firearm Printing Prevention Act,” on February 17th. The bill would ban the sale or transfer of any 3D printer in California unless it appears on a state-maintained roster of approved makes and models… certified by the Department of Justice as equipped with “firearm blocking technology.” Manufacturers would need to submit attestations for every make and model. The DOJ would publish a list. If your printer isn’t on the list by March 1, 2029, it can’t be sold. In addition, knowingly disabling or circumventing the blocking software is a misdemeanor.

      It’s very funny that people think they need a 3D printer to make a tube, a stock, and a trigger.

      If you can make a rubber band gun, you’re 70% of the way to a working firearm. And it’ll be sturdier then extruded plastic.

    It seems like that should be invalidated as a law? Like it would be if the feds pre-empted it.

    But the courts have previously ruled that you can’t illegalize dual use devices that have legitimate legal uses and possible illegal ones, as they tried to do with CD burners back in the day for the record companies, may they burn in hell.

    Not sure that would apply?

      If it involves firearms then the law, constitution and existing precedent mean nothing to the 9th Circuit of Appeals. When it comes to guns, no right is too important to not invalidate to prevent guns.

    How does this “firearm blocking technology” even work? How does a 3d printer id whatever code the slicer sends it as a gun part?

      The only possible way I can think of to make this work is require the firmware to only be able to print G-code files that have a cryptographic signature from some central slicing authority that users submit models to, which then analyzes the STL file with AI or some shit for approval. The only technology that can remotely go “is this STL file a piece of a gun?” is machine learning. You’re outright not going to get that done on the 3D printer locally; you’d have to increase the processing power of a 3D printer control board from “microcontroller” to “GPU” entirely for this dumbass tech. Maybe you’d run that on the user’s PC but PCs aren’t for sale to the public anymore so it will be done in the cloud.

      It occurs to me that these initiatives are all popping up on the West coast where Microsoft, Google and OpenAI are based. The other day the CEO of Microsoft came out and said “We’re going to have to figure out something for our bullshit tech to actually do before the unwashed masses riot.” and what do you know, a couple states that are home to large AI firms start proposing legislation that can practically only be answered by AI out of the blue.

        Yeah it seems like this is an excuse to implement complete surveillance of these machines under the guise of preventing guns, just like child abuse is used to justify age checks and chatcontrol to id everyone with id and biometrics and connect them to everything they say or do, in person and online, and make secret social scores, Palantir making those scores at that, the one that wants to use drones to spray people he doesn’t like, like his critics, with fentanyl, by his own words.

        Every addition of spying by the government is accompanied by giving more spying power, and commercial value, to tech companies as well. They are co conspirators.

    Sooooo you want to stop gun violence in the US so your first instinct is to fuck over 3D printers because gun violence is okay as long as the guns are bought from the normal vendors?

      The 3D printing lobby isn’t as big as the NRA.

      I don’t think it has anything to do with gun manufacturers, or gun violence. Someone who wants to shoot something is going to find a way.

      I’m betting it’s pressure from AI companies. “We need to find a use for this product soon or we’ll lose social permission” or whatever Mr. Microsoft said the other day. And suddenly a couple of states that have big AI companies in them propose legislation that could only be answered by large amounts of machine learning power.

      This isn’t in reaction to some shooting with a 3D printed gun, is it? I’d have heard about that, the America Bad crowd here on Lemmy wouldn’t have passed up a chance to blast that from the rooftops if it had happened. School shootings have faded into the background; that’s not “newsworthy” anymore because it’s become normal. A shooting with a 3D printed gun would have made headlines, and it hasn’t. Until we all got used to it and moved our attention elsewhere, there would be a shooting, the 24 hour tabloids would broadcast a liberal arts major’s understanding of the firearms used, the bleeding heart left would call for a ban on those specific kinds of guns, the childrape right would call them retards for getting the technical details extremely wrong, a governor 3 states away would sign a ban on bayonet lugs and collapsible stocks on rifles, in time for someone to shoot up an army base with a pistol. If a 3D printed gun shooting had happened, you could get another round of that cycle going.

      That’s not what happened though. So what did?

      They know they can’t take the gun industry head on, so they chip at the margins. They figure hobbyists aren’t numerous enough to fight back, while the real gun owners shrug.

      Banning anything is easy. Enforcement is hard.

      When you’re next door to Arizona - regularly in the top five more prodigious gun manufacturing states - it seems absurd to worry about weapons made out of extruded plastic. Ruger & Company is going to do a better job than anything a printer can churn out.

            that’s because usians have the illusion they live in a democracy and that weapons are a right instead of a duty.

            the fact they can have a weapon doesn’t mean the regime will take lightly to dissidents, just that they can in fact have them for now. fascists certainly have them, that’s for sure.

        my current printer is powered by an arduino mega, and it’s staying that way while i can. the best appliances are the ones you can control and replace yourself if you need to. 😉

        all parts you can find at a hardware store + some 3d printed pieces. repraps and foss printers are the best period.

      And largely unenforceable. Like, it can only really block the sale of prebuilt, proprietary crap like Bamboo, but most of these things are built out of common parts that are used for a verity of applications and there are countless completely open source printers you can just built from sourced parts that this literally cannot apply to.

      Even for most of the prebuilt or kits you get you put open source firmware on it. They can boot lock the board that comes with it, technically, but the board is easy enough to replace on most printers and it’s a standard micro controller and/or raspberry pi nowadays.

      Half the time people who get those kits end up replacing various components to customize for their use case. I have a Sovol SV08 that I put stock Klipper on and want to do the multi-print-head mod someday. I’ve even considered replacing the main board with a more powerful one so I can run higher microsteps without overloading the processor.

        The abject retardation spirals off infinitely in all directions like the blades of the time knife. I mean, just out of my own twisted head:

        • they’re talking about making it illegal to traffic 3D printers that don’t have a “certified gun detection algorithm.” Okay, what part of the 3D printer are you going to control? Hot ends? Control boards? 3D printers don’t have lower receivers. If I were to disassemble my Prusa MK4S back into the ~1000 weird shaped hunks of plastic, metal plates and sticks, wires, circuit boards, nuts and bolts it came in as a kit, and then drive through California, which exact piece am I going to be arrested for carrying?

        • I can’t wait until someone Man With The Golden Gun’s one of thes “certified algorithms”, prints stuff that looks like cabinet hooks, musical instruments, a walkie-talkie case, a toy dinosaur, which clip together in a certain way to make a functioning weapon. I’ve never 3D printed a gun before, this might just get me into it.

      What the “ban” is trying to achieve. Is prevention of firearms undetectable by metal detectors.

      Though I’m not sure why that is important seeing as the bullet (as a whole) consists of lead, copper, and brass. But I suppose it can be argued it’s a lot easier to sneak through a bullet than a firearm.

      Here’s the thing. This isn’t about banning weapons. It’s about controlling access to IPs and preventing right to repair.

      A forcibly Internet connected online. Only 3D printer that has to first check a public database to see if it’s allowed to print the thing you just sent is most definitely going to be used to block you from printing parts to fix your appliances or devices.

      And definitely going to be used to provide copyright protection and blocking to IPS of large corporations and companies.

      It is specifically trying to prevent people from making firearms that is not detectable with a metal detector. You are allowed to create your own firearm. As long as it is detectable with a metal detector.

    Even if this bill was in good faith, I wouldn’t want it: I believe that the USA is headed into a civil war, and I want the good guys to have the ability to manufacture stuff if they need to. Be it guns or tractor parts, having flexible logistics will be invaluable. Not just for military use, but also for civilians who don’t have access to official parts.

    In any case, the implementation of universal healthcare and UBI would be much more helpful for quelling violence. People who can have access to mental healthcare and with enough prosperity, are much less likely to become deranged enough to murder people. Measures like this, often exist to keep the peasants from being able to rise up against their overlords.

    This thing is a product of malicious greed, not for the sake of good.

      Even if it was in good faith: 3D printed guns are not a problem. Even if you made one it is going to jam up very quickly due to softening and melting, if not just explode all together.

      It would be easier, faster, and more effective to build a gun from things sourced at the local hardware store.

      Even then, If someone is going to commit a crime with a gun they are unlikely to build it themselves. Most guns used in crimes are actually legally purchased, purchased at a gunshow, or purchased on the black market.

      Anyone 3D printing a gun is doing it as a novelty. Because of that I don’t see this as a second amendment violation. This is blantantly a first and fourth violation.
