3D Printed Rocket Engine Combustion Chamber
According to Engineers at Marshall Space Flight Center, “it records the test-firing of a 3D-printed combustion chamber. Researchers are exploring advanced additive manufacturing solutions, introducing higher-performing alloys and refined printing processes.”
We are curious, so from some comments,
3D printed? From what material? How?
What kind of printer? Is there a video of printing this engine?
How does one hemisphere constitute one chamber?

NASA’s Centennial Challenges
According to Monsi Roman, program manager for NASA’s Centennial Challenges and Lex Akers, dean of Bradley’s Caterpillar College of Engineering and Technology,”The final milestone of this competition is a culmination of extremely hard work by bright, inventive minds who are helping us advance the technologies we need for a sustainable human presence on the Moon, and then on Mars. We celebrate their vision, dedication, and innovation in developing concepts that will not only further NASA’s deep-space goals, but also provide viable housing solutions right here on Earth.
It is an impressive achievement for these two teams to demonstrate this disruptive and terrific 3D-printing technology at such a large scale. By teaming up with NASA and Caterpillar, we are proud to bring these teams together in an environment where they can innovate, create and challenge our vision of what’s possible. Congratulations to both teams for their accomplishments.”
