Russian Researchers Design 3D-Printed Bullets that Test Successfully

Researchers at the Russian Fund for Perspective Research used a form of laser sintering to create 3D printed bullets, with powdered metal fused layer by layer to create a complete bullet without seams or weaknesses. The research shows that the manufacturing process is a plausible one, and could reasonably used to create specific designs or even molds with which multiple bullets could then be cast from lead or other materials.
