3D Printed Rocket Engine

Rocket Lab's latest electron rocket that launched into orbit on Saturday 20/1/2018 uses a 3D printed engine and electrically driven fuel pumps and composite fuel tanks. This video goes into a bit more detail about the rocket. Alas, 3D printing is just mentioned as aa side note.

Space X engines also use 3D printed parts. I have rumors that 3D printer is becoming a standard even with the big boys.
