3D-printed firearms used in German synagogue shooting
creation of 3D printed guns by the neo-Nazi who attacked a synagogue in Germany must act as a warning to security services, experts have said. Stephan Balliet, 27, only took one plastic weapon on the rampage that left two people dead but had manufactured several more, documents reveal. In a manifesto uploaded online, Balliet described in detail the handassembled weapons in his arsenal. He live streamed the attack in a move echoing the Christchurch shooting.
