What makes jet engines less printable than rocket engines?
- topspin 7d agoGE9X aircraft engines have 3D printed low pressure turbine blades, so I think the view that jets are somehow exceptional is already disproven. There are real benefits to using additive processes for turbojet/fan applications: many jet components have intricate passages and bizarre shapes to conduct gasses, and they are hideously expensive to manufacture with conventional tools.
