A Backpack-Sized, 3D-Printed Miniature Jet Engine

A team of GE technicians, engineers, and machinists at an Additive Development Center in Cincinnati recently created a 3D-printed miniature jet engine that’s the size of a backpack. The engine was created using layers of metal powder melted onto each other rather than cutting pieces out of metal.

The GE team couldn’t build the complexity of a whole commercial aircraft engine into their working model. Instead, they got plans for a simpler engine developed for remote control model planes and customized them for their 3D printing machines. Their final product measures around a foot long by about eight inches tall.
