Important to note: 3D PRINTED FIREARMS DO NOT BREAK WITH A FEW USES
Firsthand knowledge.
200-250 rounds and still going strong, inspected before and after firing every time
No damage so far.
Beyond that point, I agree with everything posted.
Yeah 3d printed gun is such a misnomer for most of the "ghost guns", the gun he had was just the printed frame. That section of the 3d printing community isn't really my scene but that seems to be what I've seen for all the printed guns, lower/frame with barrel and trigger assembly being metal pieces. I think years ago I saw a modern reinterpreting of the WW2 Liberator that was done in all plastic but that's obviously designed to shoot only once.
I'm sure you know more about the scene than I do and can correct or verify my knowledge.
To add on to what you said, only the lower recievers for most guns have to be registered. Someone could hypothetically get every other upper part for a pistol or rifle delivered directly to their door or PO box with no questions asked, and then just hypothetically 3d print the lower reciever.
