The Shots Heard 'Round The World

Can you make a firearm using 3D-printed parts? People are trying:

"In May 2011, a year before Defense Distributed began, a mechanical engineer and amateur gunsmith named Michael Guslick successfully fabricated the lower receiver of an AR-15 rifle (the same weapon that was purchased legally by the Aurora, Colorado shooter) with the help of an industrial Stratasys FDM1600 printer that he bought on the secondary market. The receiver is the element of the gun that houses the trigger mechanism and magazine, without which it wouldn’t function. As such, the receiver alone is officially classified as a firearm under U.S. law and is strictly controlled. The part usually holds the weapon’s serial number, which Guslick’s certainly lacked.

"Guslick, whose mild voice and intensely technical internet persona is far more suited to a father tinkering in his garage than a terrorist, assembled the full rifle with parts that can be purchased online and fired it on July 1, 2012. The resulting shooting session was likely the first time a DIY gun with 3D-printed elements was successfully fired. Blogger Turomar at Ambulatory Armament Depot posted this video of a shooting session using his own AR-15 with a 3D-printed lower receiver in August."
