The Army Has 3d Printed A Grenade Launcher

Not only is the grande launcher 3D printed, so is the ammo. The kicker? It's named RAMBO (Rapid Additively Manufactured Ballistics Ordnance). Sylvester Stallone would be proud.

The printed grenade launcher, named RAMBO (Rapid Additively Manufactured Ballistics Ordnance), was the culmination of six months of collaborative effort by the U.S. Army Research, Development and Engineering Command (RDECOM), the U.S. Army Manufacturing Technology (ManTech) Program and America Makes, the national accelerator for additive manufacturing and 3-D printing.
