Based on those ‘how it was invented’ shows, innovations has historically been tied to random passionate people in sheds who then get exploited or even straight up robbed by big industry.
Comment on New York's 3D printer law is NOT gun control; it's just.... control.

Fun fact, you don’t need a 3d printer to make ghost guns, and you’ve never needed them.
Laws restricting printers aren’t about firearms, it’s about restricting access to disruptive technology before it disrupts too much of how we innovate. (Because innovation has historically been tied to big-industry with the little guy being unable to get into it. Because it costs a shit ton.)

Yup.
But they want to control the pipeline all the same.
Semi_Hemi_Demigod@lemmy.world 1 week ago It would be awesome for a bunch of woodworkers to carve some ghost guns to show how stupid this is. Printing can’t be that much stronger than oak, so it should work.

It should be totally possible to whittle a functional AR-15 lower. Especially if you wanted to mate it to one of those fancy new bufferless uppers, so you wouldn’t even have to worry about the stock and buffer tube.
in_my_honest_opinion@piefed.social 1 week ago
The bufferless part is a bit of a sticky widget as the back of the reciever usually stops the rearward travel of the BCG. So actually buffer tubes being made from steel and allowing for slower deceleration of the BCG make for a better candidate for “softer” lowers.
If there is buffer less upper that doesn’t use the lower receiver as the backstop for the BCG please let me know. I stopped following shotshow a decade ago.
dual_sport_dork@lemmy.world 1 week ago
I’m not 100% certain. Possibly the Brownell’s BRN-180, although I haven’t handled one personally to see if the endstop block it comes with relies on the rigidity of the buffer tube ring to stop the bolt carrier or if it attaches to the rest of the upper itself in some way. The recoil springs are entirely captive and attached to it, at least.
I suppose you could also just reinforce the shit out of that area in your design if you knew you didn’t need to have a big hole through it.
FuglyDuck@lemmy.world 1 week ago
part of the problem with that is that most of your ghost guns are “just” the AR 15 lower receiver- the part classified as the “firearm” because of some technicality only a lawyer can understand.
It’s not a load bearing, nor is it exposed to any particularly high levels of heat, nor any sort of particularly nasty gasses. So that can be printed in just about anything if the printer’s resolution is good enough. (IIRC, they typically call for resin printers.)
Then, the ghost gun peeps just buy the rest of the components retail and pay cash.
for fully-printed firearms, you’re looking at things like DMLS or other kinds of precision metalwork. It’s the kind of work that would be more expensive than roadtripping to arizona and getting loophole-gun.

Couldn’t you just, idk. Use a small diameter steel pipe and the rest of it printed? Maybe im missing a whole crapload of physics for that to be sufficient
Bluewing@lemmy.world 1 week ago
Chamber pressures for the 5.56 Nato is 58,000psi. And 9mm is 35,000psi. It takes a pretty good piece of pipe to contain those pressures. Your average seam welded pipe is around 4000 to maybe 10,000 psi.
Zip guns made from hardware store pipe are just barely good enough to contain a low pressure 12ga bird shot shell.

people have been making zip guns for over 100 years.

Laws restricting printers aren’t about firearms
No I think they are definitely about firearms and how they don’t want people printing untraceable Glocks and suppressors and assassinating Our Betters in broad daylight with them.
FuglyDuck@lemmy.world 1 week ago
Don’t need a printer to do any of that. it’s also faster just to drive to a state that allows gunshow loopholes and buy an otherwise untraceable firearm. takes less skill, too.
Carmakazi@piefed.social 1 week ago
All true, but doesn’t mean they can’t be motivated by a red herring.
artyom@piefed.social 1 week ago
Yep you can make a zip gun with a couple pieces of pipe and a nail.

I honestly think those are better than the printed plastic versions in every use case except one.
sylver_dragon@lemmy.world 1 week ago
You can buy resin molds for the AR-15 lower, which is the regulated part. Then just buy all of the non-regulated parts retail and assemble a “ghost gun”. There’s also things like the FGC-9 which is mostly printed parts. And the Luty SMG if you’re skilled enough.
This genie is so far out of the bottle, it’s lapped the regulators and is going around again.
The Luty is probably less reliable than the fgc-9, RIP J Stark.
