The 3D printed gun, called 'The Liberator', was made by Cody Wilson, the 25-year-old University of Texas law student who was the star of Motherboard's documentary Click. Print. Gun. Wilson has built the prototype weapon above and plans to release the CAD files for the gun next week to the public. Basically, anyone will then be able to print the weapon with no background checks or serial numbers.
Forbes says that the Liberator is made from sixteen different pieces and uses interchangeable barrels for different calibers. All those pieces are made from ABS plastic and formed from a Stratasys Dimension SST printer. The gun also uses a nail to act as its firing pin and Wilson added a six ounce piece of steel to the gun so it can be recognized by metal detectors. Kind! But of course, people who print this gun themselves won't be required to do that. Plastic guns aren't just toys anymore. More here.
