Pratt & Whitney R 985

[Corvair]

This is a model that I printed using a Z Corp 510 and a Makergear M2. Some parts were machined and some were off the shelf. The ignition harness is stainless steel as are the push rod tubes. Stand is aluminum as is the main shaft. Prop and hub is PLA. Crankcase, Heads, Cylinders and Turbo housing and plates are powder. Although I am making the next one all in PLA on the Makergear M2 using Raptor filiment. Over 100 nyloc nuts and set screws were used. I think that 3D is not only the plastic printing (and powder and metal) but the ability to use all possible and available abilities to create something useful, functional or ascetically pleasing . I designed the solid model in IRONCAD using the best photos I could find and some manuals. I had no blueprints. See pictures in following post. Clicking on this attachment only downloads picture.
