The world's first gun made with 3D printer technology has been successfully fired in the US.
The controversial group which created the firearm, Defense Distributed, plans to make the blueprints available online.
3D printing has been hailed as the future of manufacturing.
The technology works by building up layer upon layer of material - typically plastic - to build complex solid objects.
The idea is that as the printers become cheaper, instead of buying goods from shops, consumers will instead be able to download designs and print out the items at home.
The gun was made on a 3D printer that cost $8,000 (£5,140) from the online auction site eBay.
It was assembled from separate printed components made from ABS plastic - only the firing pin was made from metal.
