U.S. Navy Creates Submarine Using 3D Printer

In July, the U.S. Navy teamed with the Naval Surface Warfare Center Carderock Division and the Oak Ridge National Laboratory (ORNL) to create the first prototype of a 3D- printed submarine. The 30-foot craft — which unlike a typical submarine will be waterfilled — can carry four to six Navy divers who will be on open-circuit scuba or rebreathers. The sub also can be operated unmanned.
