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.

The miniature jet engine the engineers at GE built was actually a modified version of one you’d find in an RC model plane. As a result, it’s incredibly simple and basic compared to the jet ...

Engineers have managed to shrink the modern jet engine until it is small enough to fit in model planes.

In the spirit of speed, [James Whomsley] strapped a jet turbine engine to an RC car, and learned some hard lessons along the way.
