The 3D printing process fascinates the staff here at EngineLabs; much like CNC machinery building billet cylinder heads, the 3-D printing process of creating something from raw materials is one that mesmerizes. And when it’s an item like this working version of a B787’s GE Turbofan engine, it’s even more enthralling.

RC Groups Forum user Harcoreta built this scale replica of the engine, with a few minor modifications, and intends to eventually power a model airplane with the engine. One thing to note–the engine does not use jet fuel; rather, it’s powered by an NTM 1400kv 35mm electric motor.

Other specifications on the engine include 18 100mm diameter blades, 24 outlet guide vanes, and 34mm diameter 18 blades internal turbine to help keep the motor cool. He didn’t stop with the creation of the engine–he also whipped up the thrust reverser system complete with translating cowl, blocker door, and cascades.

Even with the change to electric propulsion, this beast still has enough power to knock things off the table as it spools up. It was built with a Prusa i3 3D printer using plastic. The six-page thread on the forum details much of the build and assembly process; it’s interesting if you’re into the technical details.

It’s amazing that there are people who can find the time, energy, and skill to take a full-size jet engine, scale it down, and then create it–from nothing–while the rest of us struggle to figure out what happened to the remote control. Click play and listen to this beast wind up!
