Mandatory registration of all 3D printers.
Make possession of an unregistered 3D printer a felony.
Make possession or distribution of 3D-printer files for the manufacture of firearm parts a capital offense.
Turn enforcement of these provisions over to ATF, making them the BATFE3D.
This is so ludicrous an idea that you just know its going to happen.
“Mandatory registration of all 3D printers.”
Communist countries have mandatory registration of copiers and printers for the same reason. We must likewise oppose such registration for the same reason: freedom.
