Marvel At This 3D-Printed Mazda 13B Rotary Engine Model

This 3D-printed 13B model even has LED lights that give a visual demonstration of a rotary combustion cycle

This isn’t the first time we’ve looked at the work of Eric Harrell. He has an incredible back-catalogue of amazingly detailed engine models he’s made, with greats like the GM LS3 V8 and the Subaru EJ20 recreated via home-brewed kits of 3D-printed parts.

This is the first time we’ve seen him create a rotary model, however. It’s intended to be a one-third recreation of the Mazda RX-7’s 13B-REW, although Harrell admits that the “parts look right but are not dimensionally accurate.”

Regardless, there’s some incredible detail to the model, which even includes LED lights in the rotors that light up to demonstrate how the combustion cycle of the engine works.

We are in awe…

There’s an oil joke to be had here, but I’m not that slick.

Instead of oil, it will run on ink.
