NY bill would require a criminal history background check for the purchase of a 3D printer::Requires a criminal history background check for the purchase of a three-dimensional printer capable of creating firearms; prohibits sale to a person who would be disqualified on the basis of criminal history from being granted a license to possess a firearm.
You can make a completely 3D printed gun that will survive at least one shot. I’m sure if you’re using resin or carbon fiber reinforced plastic so you could probably get more than one shot off.
Resin is generally more brittle than filament, FYI, and the real question with most 3D-printed firearms is whether the shooter survives “at least one shot”.
Most 3d printed guns are either redesigns of existing guns replacing non pressure bearing parts with printed parts (look up FMDA17 a 3D printed Glock 17 equivalent) or mostly printed with pressure bearing parts being barstock or pipes (see FGC-9).
That may usually survive that one shot.
Or it may fail and cause damage to the person foolish enough to be weilding it.
