Controversy has erupted over a plastic gun created from a design fed into a 3D printer — a weapon that could conceivably be smuggled past weapons detectors and create a major security breach at airports, courthouses and schools.
The so-called “3D gun” was created by a group called Defense Distributed which fed digital blueprints of a working firearm into a 3D printer, which then casts a hard polymer mold. It said its initial firing tests of the first gun — created by the printer for a cost of about $8,000 — were successful.
The only nonplastic part of the weapon is a single nail which is used as the weapon’s firing pin. That metal pin allows the weapon to escape federal laws banning the possession of undetectable firearms.
