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.
