NASA Tests 3D-Printed Rocket Engine Part

Went well

Nasa has announced it has successfully tested a 3D-printed rocket engine part.

The US space agency said that the injector component could be made more quickly and cheaply using the technique.

The part is used to deliver liquid oxygen and hydrogen gas to an engine's combustion chamber.

The news follows General Electric's revelation that it planned to use 3D printing technology to make fuel nozzles for its jet engines.
