Fully Functional 3D Printed Engines?!? - Maker Faire


We spoke with Eric Harrell, a mechanical engineer with an obsession for internal combustion engines! Using a combination of CAD design, low-cost 3D printing, and a love for internal combustion engines, he has created working models of several engines, transmissions, and differentials. All with cutouts so you can see what’s going on. And, when we say they’re fully functional, you can change gears and switch from two to four wheel drive! Even if combustion engines are on their way out, this is a great teaching tool and fascinating to see.
