Leveraging Metal 3D Printing & Advanced Design Software for Advanced Rocket Propulsion Development
Mark II Injector Block Approx. 5in3 (130 mm2) – Material: Ti 6AI-4V
In collaboration with Velo3D and nTopology, Aerojet Rocketdyne undertook the development of an advanced “quad” reaction control system (RCS) for propulsion, aimed at supporting NASA’s Artemis program. The initiative targeted substantial enhancements in affordability, reliability, and performance to meet the demanding requirements of lunar exploration. Utilizing Velo3D’s fully integrated metal additive manufacturing (AM) solution and nTopology’s advanced design software, Aerojet Rocketdyne achieved remarkable results in streamlining production, reducing part complexity, and enhancing functionality.
