Submission + - GE is 3D printing a working jet engine...

lurking_giant writes: GE Aviation's Additive Development Center near Cincinnati has produced a number of firsts... but they are now demonstrating a working jet engine, (OK, it's sized for an RC model) The engine turns at 33,000 RPM and is made from all 3D metal printed parts.
They used the same EOS M270 3D printer that they use to produce the first and only FAA flight approved hardware, a T25 Pres and temp sensor for use in GE90 jumbo jet engines.
