Leveraging Metal 3D Printing & Advanced Design Software for Advanced Rocket Propulsion Development

Aerojet Rocketdyne is a manufacturer of advanced energetic systems. The company has been involved in many important projects throughout its history, including propulsion system development for NASA’s Artemis program, which aims to establish a station in lunar orbit and a permanent camp on the surface of the moon.
In this case study, you will learn how Aerojet Rocketdyne engineers leveraged Velo3D’s end-to-end 3D metal additive manufacturing (AM) solution and nTopology’s design software to print a near net shape lightweight and efficient “quad” reaction control system (RCS) to drive down the propulsion cost and production schedule—all while improving performance.
