Maybe the dumbest possible idea here from government regulators. You think you're going to somehow legislate certain geometry out of existence? "Sorry, you can't print that ILLEGAL SHAPE with the printer you own!" Same vacant headed assholes that think they can ban encryption. Fuck off, shrivel up and perish, please.

[–] golden_zealot@lemmy.ml 3 points 6 days ago

Impossible. The only actual discourse I think they have is to either ban 3d printers outright, require that filament/resin etc designed for these is made somehow traceable, or license and/or registrate the purchase and/or used of the printers/filaments.

Can we get the names of these people so we can have their drivers licenses taken away?

[–] Thcdenton@lemmy.world 2 points 6 days ago

Yeah good luck with that fuckheads

[–] Max_P@lemmy.max-p.me 83 points 1 week ago (1 children)

Good luck with that given 3D printers are full of open-source software.

[–] kent_eh@lemmy.ca 40 points 1 week ago (1 children)

Don't bring that to their attention- they'll start banning open source too.

Yes, because it's so difficult to get a gun in America any other way /s

Taking this purely as an engineering task, how is this remotely possible? I can barely begin to imagine how restrictions on what can be printed could be set. Am I missing something obvious? Some kind of contextual understanding of the object seems to be necessary... please don't tell me their proposed solution is AI.

In any case it will never work because 3D printing is so easy for makers to do from scratch, so any solution will fail to prevent printed guns from being made.

Again, this is just the pragmatic engineering angle. Please don't respond with political arguments.

[–] Professorozone@lemmy.world 1 points 6 days ago

Yup, this just sounds impossible without just banning the printers. Guns don't have to conform to typical gun shapes. You could just print anything that can function as a barrel and some of the other pieces and then just go in the garage and whittle a handle from a piece of wood or something. Make a part that is much larger and then just cut off the piece you want. I mean there are so many ways around this it's not even funny.

[–] MoonMelon@lemmy.ml 13 points 1 week ago* (last edited 1 week ago) (2 children)

Just spitballing but you'd have to align the desired shape somehow, perhaps with a singular value decomposition. Once its transform was normalized you could compare its shape, or perhaps its convex hull, with a database of banned shapes.

The problem is this is pretty easy to defeat (by adding extra sprues and spikes to the object, breaking it into two shapes, etc) and the more aggressive you get with the check the more you risk false positives.

An AI training set would involve creating a dataset of all the banned shapes, then generating tens of thousands of permutations of them however you believe people might try to trick it. Ultimately the AI would lock onto some small feature of the shape that scores it as positive, perhaps something trivial. That also leads to weird false positives. This also creates an arms race as people figure out what that feature is subvert it.

This problem is much harder in 3D than in 2D (currency). Since you can also cut, file, and glue shit that comes out of a 3D printer later I don't think this is a solvable problem. Like most gun control measures in the USA it appears to be aesthetics.

You could also just aggressively go false positive all over the place and say "fuck the users", with exceptions for cops. This is basically the USA's approach to drones.

Since the best available firmware is open source I don't see any way of imposing limits on it.

The printer itself doesn't even know what it's making since it's reading directions one by one, so any limits would need to be implemented at a slicer level, which are also basically all open source (at least any worth using).

The only way I could see it working would be mandating that all printers sold in the US come with software checks against it and be non reflashable, but considering a new driver board that would be able to drive 95% of printers is about $25 it is nothing more than screaming into the void.

[–] TonyTonyChopper@mander.xyz 5 points 6 days ago* (last edited 6 days ago)

You can also build a 3d printer from scratch pretty easily. Would need to regulate random electronics and robotics components

[–] Laser@feddit.org 0 points 6 days ago

Open source firmware doesn't mean anything as long as tivoization is happening.

Which I don't know whether it's the case, but legislature might make this a requirement.

They should put controls on lathes and mills to prevent making guns. Metal guns are a lot more effective than plastic guns anyways. /s

There is essentially no way to enforce, or even monitor this, like it's fundamentally impossible without controlling everything from stl creation, to weapon construction.

I love technological non-solutions to social problems. They are the only thing the work better then passing more laws that say you can't murder people with guns.

I see 10,000 forks in the near future, and fully decentralized ways of hosting them. God forbid we actually try to regulate real guns, no it's those damn hobbyists who spent thousands on printers!

Trying to stop a printer from printing sounds like a tough ask.

[–] VerilyFemme@lemmy.blahaj.zone 2 points 6 days ago (1 children)

Maybe they can partner with Epson or Brother, they're pretty good at keeping their printers from printing

The pressure behind a bullet ~14,000psi. The pressure that a 3D resin can handle ~ 200psi. Any questions?

Oh yeah, how do 3D printed guns kill? 1) use non 3d printed parts or 2, hold the bullets in the gun-like case, carry a hammer, if you need to shoot the bullet just get the bullet out between two of your fingers, run like crazy towards the target, then bury that sucker with a real nice hammer thud. If you practice real good, you can hit a good 3 or 4 target spots. If you do it it slow enough you can probably hit one bullet with another bullet! Well, you can always do that. Heck you can put 10 bullets or more in a baggie and they will all hit each other.

I guess if you need a ruzzian war diy survivor gun, just go-to the hardware store and get a pipe. No 3D printed stuff. You can make the handle from wood! That's literally all a 3D printer is good for in gun making, the handle. But you can carve one out with a router. Are routers illegal yet because you can make a gun .... handle....?

[–] Etterra@lemmy.world 21 points 1 week ago

Yeah like that won't be bypassed in about 3 seconds.

[–] x00za@lemmy.dbzer0.com 20 points 1 week ago (2 children)

It's like governments are trying to get people to listen to them instead of doing their job: listening to what the people want.

Stop making stupid rules and start looking at the causes and work with that. Why do people want 3d printed guns? Well to either protect themselves, do something bad, or for fun because they can. Ok maybe we should look at why the hell do people feel the need to protect themselves instead of letting the police do that? Maybe look at why people do bad things? Hint it's mostly money, which you are taking away from them. Or try and fight people having "fun"? Well you could always take away the fun with even more rules.

The biggest win of the ones in power was to make the concept of anarchy look like chaos. :)

even if police were perfect plenty of people would still want to do it themselves, as with anything there will be hobbyists. Some hobbies are more legal than others.

This isn't really about safety, it's about gun manufacturer profits.

Like how machine gun owners don’t support the repeal of the nfa or fopa because it would tank the value of their stamp items.
