3D Printed Rocket Parts and the Future of Spacecraft

Hot-fire testing of an additively manufactured copper alloy combustion chamber and a nozzle.
Future lunar landers might come equipped with 3D printed rocket engine parts that help bring down overall manufacturing costs and reduce production time.

Future lunar landers might come equipped with 3D printed rocket engine parts that help bring down overall manufacturing costs and reduce production time. NASA is investing in advanced manufacturing – one of five industries of the future – to make it possible.

Through a series of hot-fire tests in November, NASA demonstrated that two additively manufactured engine components – a copper alloy combustion chamber and nozzle made of a high-strength hydrogen resistant alloy – could withstand the same extreme combustion environments that traditionally manufactured metal structures experience in flight.

This image shows the hot-fire testing of an additively manufactured copper alloy combustion chamber and a nozzle made of a high-strength hydrogen resistant alloy.
