I think you should keep an eye out for Relativity Space, their rocket is soon to launch, and the whole thing is, and I am not exaggerating, fully 3d printed. It's a wonderful design and I hope it works, because it automates a great deal of the process. Veritasium did a video on their rocket: [VIDEO]

Relativity Space are also 3-D printing not just rocket engines, but entire rockets, and have had a successful first flight. [VIDEO]

What part is not true? [VIDEO] I'm sure that there are lots of problems with this approach, but it is not as obvious as your comment makes it out to be.
