Uhhhh my friend you can print a 9mm CZ scorpion that shoots as well as the real thing. Same with an MP5. You can find videos of them being tested and shot on the internet. A lot has changed in the past few years with 3D printed guns.

No plastic can withstand the pressure and shock from the propulsion of the shot, nor the heat or the friction generated. The 3D printed whatever is a fallacy. The only thing you can print is cute things you can attach to whatever.

Ngl I was hoping for The Glong lmao, close though!

Only the non critical to function parts can be plastic. IE, the barrel can’t be plastic. And you can use literally anything else other than 3D printed stuff.
So why is 3D printed even an issue. Anything… A CNC, scissors, metal, a grinder, wood, springs, screws…can be made part of or be used to make anything else. Making things is not magic and a 3D printer is not magic either.
The highest pressure rated plastic has a Ts or just maybe 28ksi. But with 15% elongation and a really weak modulus. So you can make toys basically.

In the United States, only the lower is considered a gun. There’s no check needed to buy the barrel or slide components.

You kidding? I know nothing about these things but that sounds just wrong.

This just isn’t reality. For .22lr, nearly 100% of the gun can be plastic, including the barrel. Here are two real examples where the only required metal component is the firing pin:

3dprint.com/…/worlds-1st-3d-printed-revolver/
For more reliable and more powerful guns, some critical components must be metal, of course, like the barrel might at least require a liner, but the majority of the gun and internal mechanism can still be plastic, not only non-functional or cosmetic parts.
And you can use literally anything else other than 3D printed stuff. So why is 3D printed even an issue.
Idk, I didn’t say it is. I’m just informing you that 3D printed guns are real, not a “fallacy”, some function very well and reliably, and can actually be made with almost no or minimal metal parts

But the issue at hand is about regulating 3D printers. So how about HF CNC machines? Or lathe mill combos? What about resin?
What about meat? It has vitamins and proteins to make some people really really strong… Enough to choke people with their bare hands! And they are allowed to freely walk among us and even ride the bus, train our plane! Protein is very dangerous stuff. I hear you can even 3D print it!

It’s a hell of a statement considering theres tons of videos and evidence that prove the opposite of what you just said.

Yeah, cute things like an unregistered glock 19 lower printed at a 45 degree angle out of pla+ you can attach to a trigger and rails via pins, rails that themselves connect to a glock 19 upper?
Hmmm…

You 3D print the frame, which is plastic on many modern pistols nowadays anyway. Then buy a barrel and a slide online, which don’t require a background check as they are not considered a firearm on their own.
