This first bill allows the state of California to regulate and oversee all 3D prints in the name of public safety.
Proposal: All elected officials must install Corruption Blocking Software that scans all their communications, financial records and assets, and uses advanced Corruption Pattern Matching Algorithms to determine if they might be taking bribes from industry lobbyists, pumping up their own investments, or secretly serving special interest groups, or if they’re just general nutjobs.
It’s also pretty much a technical impossibility if you know anything about 3D printers.
3D printers can’t read CAD. They aren’t fed STLs or any other kind of 3D model. They’re fed G-Code, which contains no geometrical details. It’s a list of instructions saying “turn these 4 motors this speed this for this amount of time while heating that part to this temperature and turning this other motor this speed, then heat this part while tunlrning that motor that fast…” with hundreds or thousands of instructions, and then new instructions for the next layer.
In order to print a model, you first have to run it through a program called a slicer that generates that G-code by slicing it into layers with instructions for how to move, heat and cool the nozzle, build plate, and chamber, feed the filament, etc.
The printers just follow those instructions with minimal on-board processing and zero information regarding the final model’s structure.
to comply, vendors would need to require printers sold in california to be locked (presumably by encryption) to a proprietary slicer with ai vision that could try to determine if the thing being printed looked like a gun. Maybe if there was a bullet sized barrel and access around the striker area.
Makerbot more or less did this. It was a pain in the ass to use a non-makerbot-desktop slicer with a 2/2x series.
But the most popular brand right now forces server interaction.
Speaking as someone that knows basically nothing about 3d printing (though has done similar with CNC), do you think it’d be possible to reverse-engineer the code in some way? I’m thinking something like a simulated 3d printer 🤷♀️
You can, sure. but then you have a new file that is entirely distinct from the original model (as far as computer hashing is concerned). So you have to do several steps to legally comply with this:
-
Receive gcode file
-
use costly ai to convert the gcode to a 3d model.
-
use costly ai to try to figure out what the 3d model is.
-
do all of this either via a remote connection, or on a processor weaker than the median game console from the 1990s.
-
repeat for every single attempted print, which can be several dozen per completed product depending on how annoying the calibration was that day
So if you’re a 3d printing business you now have to have your own data center basically dedicated to the tens of millions of potential prints you’re going to receive, because it’s near impossible to fingerprint g-code as it’s dynamically generated from each different CAD software differently based on thousands of settings.
Essentially any 3d printer manufacturer is going to just say “not for use in california” instead of paying hundreds of millions of dollars a year to try to comply with this.
-
there are many open sourced software applications than can produce G-Code for any printer. All of it can be done offline.
What’s next? Monitoring ink printers? you gonna stop me from printing out an image of (insert copyright charater here)? Oh yha, they would of they could. Many wernt going to make weapons, but now they might just to defend themselves. Good job. /s
Politicians - the original Backdoor Sluts
I read the article and what a load of shit. So you can’t 3D print a cosplay gun? How far will this go? Water pistols? Ray gun props? Children’s toys. Plastic guns are not illegal, just certain ones.
If I lived in California, I think I would invest in a really good 3d printer now-ish and just never update the software. Big brother is watching everything.
Guns are just a weak excuse, as if it’s hard to get a gun in the US.
They want to monitor what you print. This means trademarked toys and figures, or copies of parts used in self-repair projects. The next stage is to charge fees to print copyright, or patented objects, or parts to repair. This also means they can spy on your designs and intellectual property.
It’s almost like governments of all sizes have been captured by companies and now protect them against the evil consumer which is completely backwards to what governmental organizations were originally created for.
Same California that is supposedly against the federal government’s assaults on people’s rights and freedoms…?
Same California governor that wants to run for president to end fascism in the country…?
What’s to stop anyone from driving out of state to buy the printer, or having it shipped from out of state? I swear to dog legislators are virtue signaling dip-shits.
Eventually they will all fall in line.
Genuine question. Would you all be fine if instead they required that printers add some sort of invisible tracking data? Similar to how 2d printers do.
I know that would be difficult to do with this tech but if it were possible.
I print toys for my kids, small pieces to fix things and not much else. While I’ve got nothing to hide, but still find this unnecessarily invasive.
I’d be ok if they didn’t track anything.
Authoritarians just doing what authoritarians do.
I’m surprised the title wasn’t sensationalized.
3D Printers getting their backdoor smashed by California lobbyists
Printing companies should stop selling in California.
Everybody should also stop considering the US like one country, because it functions less than one country than the EU and the EU isn’t and the US is.
Backdoor Bill? Haven’t seen that porno yet.
Aaaaah… If they were just so restrictive on gun laws… insert image of utopian healthy world here
Everytown for Gun Safety says recoveries of 3D-printed crime guns across 20 cities have risen nearly 1,000% over the past five years,
So… They found a total of ten 3d printed guns in the last 5 years?
Percentages without a baseline are useless.
You can find more magnet fishing.
325 are 3D out of 350,000 guns found in CA in connection to a crime in 2024, according to random assholes on reddit.
This is a pretty dumb thing to pass legislation on considering it’s still VERY easy to buy a gun even in CA, another method of getting a gun isn’t making it easier in any real sense.
and to be clear to naive: you can’t actually 3D print a gun. You can make parts that can be smithed together with metal parts to make a working gun. There are some fully plastic designs, but no way would I shoot those twice.
with metal parts to make a working gun.
That’s always convention “forgotten” in all these breathless “think of the children” arguments.
You can’t fully 3-d print a working gun that isn’t as dangerous to the user as it is to the target.
Now to be totally fair, 325 is 325 more than 0, which would be the ideal number of 3d printed guns used in crime… But also, how many of those 3d printed gun users had access to a different gun and simply opted for the 3d printed one? I get the feeling it was somewhere around 325 of them
This is all ignoring the fact that I’m using a very liberal definition of the phrase “3d printed gun.” I doubt anyone is using Songbirds for armed robberies lmao
3d printing isnt shit except for ease of use. I can make a 12 gage slam fire shotgun in a couple hours with maybe $100 on a home depot or Lowes gift card. As a machinist and welder, I can make a whole lot more than that.
On the one hand, its moronic to think that limiting 3D printing will in any way affect ease of access to firearms. On the other hand, literally anything making it harder for people to kill or harm each other is probably for the best in the long run.
A comedian I watched a while back had a bit about if the government really wanted to stop gun violence, they’d put a massive tax on ready made ammunition. You really gotta hate a bitch to spend $5k on a bullet to kill them. Obviously this doesnt take into account making your own ammo, but the point stands.
Add to that the fact that some gun parts are not printable and have to be made out of metal. Printing an entire firearm on a $500 3D printer is possible but that gun will be good enough for 1 bullet, and probably will hurt shooter at that.
Also, if inmates can make a handgun out of whatever they have access at prison - 3d printing is the afterthought. Some parts can be bought in a department store, the others can be ordered online as a replacement parts. If someone really wants to make a gun themselves, 3D printing ban wont stop them.
I might print some guns purely out of spite.
In Minecraft.
