Cool community. New member. Yep I’m well aware it’s completely legal in the US for the most part (there are a handful of states where it’s illegal so be careful) perusing this community I see 2 things that go against your claims. Not very many people specify the type of plastic, PLA and PLA+ won’t last for very long, definitely not thousands and thousands of rounds (most barrels are only rated for 10,000-20,000 rounds anyway, there’s a mill-std that military weapon accessories like scopes only need to be certified to 50,000 rounds which isn’t a lot for a machine gun, civilian standards were even lower). Happy to be wrong but I see no one claiming survivability of thousands of rounds. It’s very tough to tell what plastic is in pictures with only a few exceptions but I expect much of that is PETG. Also looking at the raw print quality I’m certain some of them are from something like an ender but a basic ender doesn’t print nice enough to just work. Those printers are going to be well upgraded and the raw prints carefully cleaned and sanded after. (Again I said specialized like the guy who did an SLS nylon ar lower in the last few days on that Reddit, or well tuned which is still not a trivial task). Basically what I’m saying in my original comment is it’s not buy printer download gun go shoot things. Without a good understanding of printers AND guns you ain’t making something effective which is why I say it’s a fools errand because if you possess both those things AND mal intent, you’re smart enough and resourceful enough to go do something else besides print a gun and use it. I found some data to back this up too claiming 44 3d printed weapon crimes in 2022 (check one of the other comments for the source). Seems governments are waisting a lot of resources on targeting dangerous 3d printers when truthfully this isn’t actually a widespread problem like so many articles are claiming
