3D-Printing Flight: The Journey Begins

GE engineers are using additive technology to take jet engine design beyond the impossible.

Engineers from GE Aviation have designed an advanced fuel nozzle tip for jet engines, and there’s no assembly required. This enhanced component—also called an injector, because it sprays fuel into the engine, enabling it to run— is 3D-printed as a single unit, rather than the 20 separate parts needed for older models. Created for the LEAP jet engine from CFM International, a 50/50 joint venture between GE and Safran Aircraft Engines, the new fuel nozzle tip is lighter and more durable than previous designs, boosting the engine’s fuel efficiency. Here are some of its improved features, previously unattainable by other means of manufacturing.
