The CAD program I am using is Fusion 360 which is free to the hobbyist. I save to an STL file under the export tab. My 3D printer is a Prusa MK 3 and I use their slicer. I can 3D print as drawn so its worth spending some extra time to get things looking as close as possible. For production of the actual engine components the drawing will be changed where needed for ease of machining.So are you making Cad drawings for the real parts to be machined ? How do you get from those drawings to the 3D printer ?
Are you just putting the cad drawing into a slicer ? Yep I'm real new to the 3D printer world .
thanks
