A pro-gun group in America has come under fire after creating the world’s first working gun using a 3D printer.
Defense Distributed, who created the weapon, has said that it will publish the blueprints online.
The group spent a year making the gun, which was successfully fired in Texas on Saturday.
Anti-gun organisations criticised the work, and Europol, the European police agency, said that they would keep an eye on the development of 3D technology to create weaponry.
The gun was made on a 3D printer bought on eBay for $8000 (£5140) and only the gun’s firing pin was made of metal.
The US Bureau of Alcohol, Tobacco and Firearms (ATF) confirmed that making a gun using a 3D printer is legal – as long as it’s not a banned type of gun.
