NASA’s 3D Printed Rocket Engine Parts Survives 23 Hot-Fire Tests

2 Mins read
After completing rigorous testing procedures in November this year, NASA, the premier space agency under the U.S. Federal Government, demonstrated that two 3D printed rocket engine components namely, a copper alloy combustion chamber and nozzle made of a high-strength hydrogen resistant alloy, have survived 23 hot-fire tests. The components had to undergo extreme combustion environments that traditionally manufactured metal structures experience in flight.
