Printing 3D objects with industrial precision with a household 3D printer isn’t easy, not even highly recommended since household printers do not usually have the reliability of their bigger purpose-built industrial brothers.
However, when some tech-savvy home-bound genius manages to put his mind together and his building skills as well, some pretty impressive things can come out, like this awesome jet-ish engine that has quite a respectable thrust. A guy from the RC Groups forum has used a 3D printer to make a fully functional scale model of a Boeing 787 GE-built turbofan jet engine.
The user, called Harcoreta, built his replica including over 60 3D printed blades and vanes on the inside, and believe it or not, it manages to produce more than enough thrust to power an RC plane. And that’s exactly why this guy built it for.
For even more extreme accuracy, Harcoreta even incorporated a functional thrust reverser into his engine. Impressive enough, he’ll be able to use that reverse thrust to not only stop his plane but have its engine put on reverse before it runs out of runway.
Specs for this are: 100mm diameter 18 blade main fan scale looking. 24 outlet guide vanes. The internal turbine 34 mm diameter 18 blade internal turbine, installed on the back shaft of the motor, while it’s designed only for cooling the motor.
