NASA has successfully hot-fire tested a 3D-printed combustion chamber for a rocket engine. This is the latest in a long series of 3D-printed rocket components that NASA has worked on over the years at its Marshall Space Flight Center.

The engine was fired to simulate launch conditions, for 25 seconds at 100 perc ent engine power. "Both parts passed with flying colors," reports Popular Mechanics.

The video below shows a subscale channel wall nozzle being hot-fire tested in November 2017 at the Marshall Space Flight Center. The nozzle was fabricated using three separate, state-of-the-art, advanced manufacturing technologies including a new process called Laser Wire Direct Closeout, which was co-developed and advanced at Marshall.
