Lightweight Combustion Chamber Part of 3D Printed Rocket Engine: The Cool Parts Show #30

Masten Space Systems developed a lightweight, reusable rocket engine for NASA’s aim to fly repeated trips to the moon in rapid sequence with little delay between launches. The “Broadsword” engine was made using laser powder bed fusion by Elementum3D on a machine from EOS. Additive manufacturing (AM) enabled sophisticated internal cooling channels and the consolidation of the engine’s parts into just three major components, all 3D printed, including the combustion chamber seen in this episode. AM also allowed for light weight through the choice of material. Rather than a high-temperature (and heavy) aerospace alloy, this chamber is made of a metal matrix composite developed by Elementum3D that combines aluminum for light weight with ceramic for high temperature performance. This episode brought to you by Carpenter Additive.
