 As the gun debate continues in the US, the one American company has created a blue print to create gun parts using a 3D printer. A group called defense¹ distributed has released instruction that anyone can download that explains how to use a 3D printer to make a AR15, the part of a semi-automatical rifle that ordinarily requires legal permission to own. 3D printers use a process called additive² manufacturing to make objects from a digital model by laying down layers of material. Today’s affordable³ 3D printers are used to make simple items like key chains and logos. 

In the wake of new town Conneticut elementary school shooting in which 20 children were gone down, anti-gun violent advocates say the prospect⁴ of duplicating illegal weapon is alarming. The AR15 information has already been downloaded more than 10,000 times since it was made available on February 25th.

“We will have the reality of a weapon system that can be printed out on your desk. Anywhere there is a computer, there is a weapon.”

The founder⁵ of the company says the goal of the release of the information is to “teach people practical anarchy⁶.”
