NASA has developed 3D printed rocket engine components that could be used as part of the Artemis project to return astronauts to the Moon, and prepare for a future mission to Mars.
Through its Rapid Analysis and Manufacturing Propulsion Technology project (RAMPT), NASA has optimized a blown powder Directed Energy Deposition (DED) technique to fabricate several large-format parts. The advanced printing process has enabled NASA to significantly reduce the lead times and costs of producing complex engine components such as nozzles and combustion chambers.
“This technology advancement is significant, as it allows us to produce the most difficult and expensive rocket engine parts for a lower price tag than in the past,” said Drew Hope, Manager of NASA’s Game Changing Development Program, which funds RAMPT. “Further, it will allow companies within and outside the aerospace industry to do the same, and apply this manufacturing technology to the medical, transportation, and infrastructure industries.”
NASA’s enhanced DED-based 3D printing process
NASA established its RAMPT program to develop novel manufacturing technologies, with the overall aim of increasing the scale and performance of its thrust chamber assemblies. At present, the rocket chamber takes the longest time to produce, is the …
