Researchers fire 3-D printed ammo out of a 3-D printed grenade launcher

Mr. Seung kook “Sunny” Burns and Mr. James Zunino for US Army Blog:  Researchers at the U.S. Army Armament Research, Development and Engineering Center (ARDEC) successfully fired the first grenade created with a 3-D printer from a grenade launcher that was produced the same way. This demonstration shows that additive manufacturing (commonly known as 3-D printing) has a potential future in weapon prototype development, which could allow engineers to provide munitions to Soldiers more quickly.

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.

RAMBO is a tangible testament to the utility and maturation of additive manufacturing.  Cont'd...

PI USA - Difference between Gantry & Split-Bridge

A traditional gantry system employs X-Y or X-Y-Z range of motion. Mounted on a base plate, usually granite, 2 parallel rails constitute the synchronized Y axis motion while the cross axis (bridge axis) provides the X motion. A vertical axis can be added on the bridge for the Z motion. A Split Bridge system can be less complex than a traditional gantry system because synchronization of the two parallel linear motors is not required. Both systems are used in industrial production, testing, and additive manufacturing.
