It may not be the most exciting engine but its the only one I had in my garage. Great if you want to learn about engines and how the moving parts in them work. All parts are printed except for a few bearings and fasteners.
More than 3 days of total print time.The block alone was 34 hours. So make sure you have a well calibrated and reliable printer.Some print times calculated in Cura at .2mm layer height. Engine Block – 40 hours.Head – 23 hours.Valve Cover – 10 hours.Oil pan – 14 hours.
This is p perfect 3D printing project that will teach you all about how engines actually function, great if you want to learn about engines and how the moving parts in them work.All parts are printed except for a few bearings and fasteners.
