Blueprints outlining how to 3D print a gun can go back online, the US Justice Department has ruled.
It follows a four-year battle between the makers of the gun, Defense Distributed, and the US State Department.
The first printed firearm was made in 2013. Files showing how to replicate the process were then put online and downloaded more than 100,000 times.
The US government ordered them to be removed shortly afterwards. . . .
The US Justice Department has now said that Americans may “access, discuss, use and reproduce” the technical data.
