have successfully created a rocket engine... fully assembled using 3D-printing technology.
I call BS on this announcement since many components like turbo-pumps cannot be 3D printed... yet. Besides, the most critical components of such engines are the alloys needed to survive the extreme temperatures. This is why US was unable to copy Russian engines. It's the secret of alloy manufacture.
