3D printed Toyota 22RE engine

Printed on a homemade RepRap Prusa 3D printer.

Completely reverse engineered Toyota 22RE 4 cylinder engine. Can completely print a fully rotating model. Working crank, pistons, and valve train. The valves open and close!!!. 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
