An American gunsmith has become the first person to construct and shoot a pistol partly made out of plastic, 3D-printed parts. The creator, user HaveBlue from the AR-15 forum, has reportedly fired 200 rounds with his part-plastic pistol without any sign of wear and tear.
HaveBlue’s custom creation is a .22-caliber pistol, formed from a 3D-printed AR-15 (M16) lower receiver, and a normal, commercial upper. In other words, the main body of the gun is plastic, while the chamber — where the bullets are actually struck — is solid metal.
The lower receiver was created using a fairly old school Stratasys 3D printer, using a normal plastic resin. HaveBlue estimates that it cost around $30 of resin to create the lower receiver, but “Makerbots and the other low cost printers exploding onto the market would bring the cost down to perhaps $10.” Commercial, off-the-shelf assault rifle lower receivers are a lot more expensive. If you want to print your own AR-15 lower receiver, HaveBlue has uploaded the schematic to Thingiverse.
HaveBlue tried to use the same lower receiver to make a full-blown .223 AR-15/M16 rifle, but it didn’t work. Funnily enough, he thinks the off-the-shelf parts are causing issues, rather than the 3D-printed part.
