A crazily talented engineer by the name of Eric Harrell of Santa Cruz, California has gone and cold printed out a 22RE engine and W56 transmission. Yes, it’s just like the one you’d find in a Toyota Hilux or 4Runner, and yes, this working scale model of one of the most famous Toyota drivetrain combinations of all time was spit out from a 3D printer and assembled.
The engine was completed first, about two months ago, and took Harrell 60 hours to design and another 72 hours to print the 80 parts it’s comprised of. Because of limitations with the printer itself, he had to scale it down 35 percent, everything works.
Harrell then followed it up with a W56, which took another 48 hours on the printer. The finished product bolts right up to the 22RE. There were a few parts that couldn’t be printed, like bearings, thin rods, and the fan belt (a rubber band). Watch the video below and be amazed. Then download and print your own engine and transmission. wait for the 3D printed Toyota Truck. Maybe.
