NASA and Virgin Orbit have 3D-printed a working rocket engine part

They have successfully test-fired 3D-printed combustion chambers made from multiple materials.
The news: By combining their manufacturing and testing capabilities, small-satellite launcher Virgin Orbit and NASA created a rocket combustion chamber that was 3D-printed from multiple metals. A combustion chamber is the container where all the propellants get mixed up and ignite—so it must be able to cope with extreme heat and force. The test part that used the chamber generated more than 2,000 pounds of thrust in a series of 60-second test fires. You can watch a video of the test firing here.
Why are chambers a challenge? Because it has to withstand so much, it must be designed to a very high standard, meaning the part is expensive and time consuming to make.
