First successful firing of a 3D-printed gun

3D printers offer the promise of a world in which anyone can manufacture anything but, as with all technology, there are upsides and downsides. Last week we learned that handcuffs could be unlocked with a 3D printed key; now "HaveBlue", a member of the AR15.com gun enthusiast forum, which is named after a common semi-automatic rifle, claims to have carried out the first successful test-firing of a 3D-printed gun.

HaveBlue did not print an entire gun but only a part called the lower receiver, which serves as a frame for the other components of the gun. This component is the only gun part regulated for sale under US law and as such must carry a serial number - unless it's made by a private individual for their personal use, so HaveBlue is not breaking any laws.

Making gun parts used to be impossible for most people, of course, but computer files for AR-15 components have been available online for some time. HaveBlue claims to have combined a 3D-printed receiver made from hard plastic with parts from an ordinary pistol and successfully fired more than 200 rounds. "To the best of my knowledge, this is the world's first 3D printed firearm to actually be tested, but I have a hard time believing that it really is the first," HaveBlue said.

HaveBlue also attempted to build a working rifle using the printed receiver, but encountered difficulties when passing ammunition through it. These issues remained after swapping out the printed receiver for an aluminium version, though, suggesting the problem lies with a non-3D printed part of the gun.
