And that’s why it’s all the more impressive that someone on the RC Groups forum has used a 3D printer to make a fully-functional scale model of a Boeing 787’s GE-built turbofan jet engine.

You can do a lot with 3D printing —even create a working model jet engine. As a final project for a jet engine manufacturing course at the University of Virginia, students led by Professor David ...

A working model engine has different materials and manufafturing process than a large full-size engine as would power an airliner or fighter. And anyone can print off a 3D model of a jet engine ...

A designer built an incredible working model of a plane engine. Footage shows the GE90 reverse-engine thrust system miniature being tested on its maker's desk in Zhejiang, China on May 22.

GE was able to create a working jet engine using an additive manufacturing technique known as direct metal laser melting. The resulting engine's turbine achieved 33,000 rpm.
