Printed Engines Propel the Next Industrial Revolution

In the fall of 2023, NASA hot fire tested an aluminum-based, 3D-printed rocket engine nozzle. What made the event remarkable is that aluminum isn’t typically used for additive manufacturing because the process causes it to crack, and it isn’t used in rocket engines due to its low melting point. Yet the test was a success.

The new possibility of printed aluminum engine parts will mean significant savings for NASA in terms of time, money, and, most importantly, the weight of future spacecraft. And Elementum 3D Inc., a partner on the project, is now bringing the benefits of that technology to its customers, including not only rocket engine manufacturers but also makers of race cars, lighting fixtures, computer chips, and more

In this image, a laser powder directed energy deposition (LP-DED) 3D printer at RPM Innovations’ facility additively manufactures a large-scale aerospike rocket engine nozzle from one of Elementum 3D’s specialized, 3D-printable aluminum alloys.
