Back in May, Defense Distributed made headlines with the world's first 3D-printed gun. Though it may have been the first, Defense Distributed's Liberator is not the only 3D-printed gun around. A Canadian last month staked a claim to the world's first 3D-printed rifle. His weapon, dubbed the Grizzly, is a .22-caliber single shot long rifle that was produced using a Stratasys Dimension 1200es 3D printer. A video released near the end of July showed the gun firing a single shot but now the Grizzly is back and better than before.Credit: ThreeD Ukulele
Last month's demo video showed the gun firing one shot that ended up splitting the gun's barrel on both sides. Things have come a long way since that first test shot, though. New videos posted to YouTube show Grizzly 2.0 successfully firing a total of 14 rounds (using Winchester Dynapoints) before developing a crack. One of the videos even shows the gun's owner hand-firing the last three shots (as opposed to pulling the trigger from a distance).
The poster of the videos and manufacturer of the gun goes by the name of ThreeD Ukulele on YouTube and says he plans to make the blueprints for the files available for download soon. However, it may not be plain sailing. Defense Distributed released the blueprints for its 3D-printed gun back in May, posting them to its website, DefCAD.org. Not too long after, the files were pulled at the behest of the US Department of Defense Trade Controls. A letter from the State Department cited potential violation of gun export laws (specifically, the International Traffic in Arms Regulations or ITARs) as the reason for the take down request and said Defense Distributed should treat the data as ITAR-controlled until it receives final determinations from the Department.
