The Undetectable Firearms Act of 1988 makes it illegal to manufacture, import, sell, ship, deliver, possess, transfer or receive any firearm that is not detectable by walk-through metal detectors or airport x-ray machines. At the time this law was passed, concern was over the damage hijackers could do should they smuggle a ceramic weapon onboard an aircraft. However, with the advent of 3-dimensional, or “3D,” printing technology, nearly undetectable plastic weapons can be constructed at home. The absence of a serial number or sales record makes these home-made firearms virtually untraceable. Although not yet reliable, these guns could still pose a danger to air travel. 3D printing, involves the programming of a 3D printing machine with a computer file that provides the schematics for the item to be printed. Advocates say that 3D printing has the potential to render gun laws obsolete, not to mention gun manufacturers.
