NASA is dipping its toes in the 3D-printing revolution pool, and it doesn't care who knows. Instead of using traditional assembly processes, the agency has used additive manufacturing to construct a rocket engine injector. This space-technology demonstration could reportedly lead to more efficient manufacturing — specifically, saving American companies time and money.

Designed by Aerojet Rocketdyne, using a method that employed high-power laser beams to melt and fuse metallic powders, the team at NASA's Glenn Research Center in Cleveland, Ohio, tested the injector with high-pressure firings of liquid oxygen and gaseous hydrogen. The tests were successful, which means the team is ready to develop full-size 3D parts.

Compared to the usual manufacturing process, which traditionally takes more than a year, printing the injector via 3D-technology took less than four months; the 3D-printed model also cost NASA 70% less than its current iteration. Glenn and Aerojet Rocketdyne partnered on the project with the Air Force Research Laboratory at Edwards Air Force Base, Calif.
