A mechanical engineering student is claiming he's made history after designing the "world's first" 3D printed revolver - capable of firing real bullets.
James Patrick's PM522 Washbear is a gun which can fire up to eight bullets between reloads. And, bar an few components, it's made entirely by a 3D printer.
According to Fox News, Patrick added detectable metal rods to comply with US gun regulations, to avoid his blueprint being removed from the internet - something which previously happened to entrepreneur Cody Wilson when he debuted his Liberator 3D printed gun in 2013.
Patrick has been "working on the gun for months", and as a result, created the world's first functional 3D-printed repeating firearm that has been printed using a consumer 3D printer.
