It was the summer of 2012 when the first news of a 3D-printed gun
surfaced, an assault rifle-style .22 that appeared on a message board devoted to the love of firearms. That weapon was believed to be the first 3D-printed gun successfully fired, but its fame was short lived, with The Liberator having caught popular attention soon after for being the first fully 3D-printed firearm
. After being successfully fired, the company behind it - Defense Distributed - released the blueprints for anyone to download, something the Department of Defense has already stymied.
