Just finished printing a cylinder head for my 175cc J.A.P engine from the 30s ,a twin port race engine . The head took 17 hours to print and will be used as a lost wax/plastic form , they just burn the plastic out and your left with the sand form . The stl program was written on Fusion 360 and printed with Simplify 3D on my German Rep Rap .Hope to get the little racer going ,its been laid dormant since 1938 !!
