Beginning in 2022, NASA will place unmanned Orion spacecraft into lunar orbit, followed by crewed landings, construction of lunar habitats and supporting infrastructure, and ultimately, preparation for a visit to Mars.

Additive manufacturing (AM), or 3D printing, is one of the technologies that enables such ambitious plans. “As with any complex endeavour, the more affordable you can make it, the greater the chance that you will ensure its completion, and the Moon is no different,” said James Horton, Aerospace Engineer and Mission Architect at Aerojet Rocketdyne. “Metal AM plays a key role in achieving these goals.”
