We've heard a lot about GE's in-progress 3D printed turboprop engine, which was first announced a year ago. The engine, which will contain multiple titanium and steel 3D printed parts, will power the Cessna Denali, a 10-person business aircraft being developed by Textron Aviation. This week, GE brought a mockup of the ATP to the EAA AirVenture event in Oshkosh, Wisconsin, allowing people to get a good look at it. Seeing it is a big deal - the engine is the result of more than a decade's worth of research and development. It's being produced with a number of processes developed by GE itself, including direct metal laser melting. It will be the first jet engine to largely be produced through additive manufacturing, as well as being the first "digital native" engine in the aviation industry.
