3D-Printed Gun Fires Real Bullets
The folks over at Defense Distributed, the home of the Wiki Weapon Project, have successfully fired an AR-15 semi-automatic rifle with a 3D-printed lower receiver. They were able to fire off only six rounds before the part failed, but some would consider that a pretty decent outcome considering it’s composed of printed plastic. Now, the entire gun is not printed–just the lower receiver (the regulated part), but it’s a good first step. Regardless of you stance on gun control (or conceptual lack thereof), this project is worth keeping an eye on.

As the plastic pads that cover its outer surface detonates the ordnance, the device absorbs the impact of the blast with minimal damage.
