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.
That may usually survive that one shot.
Or it may fail and cause damage to the person foolish enough to be weilding it.
