The housing for the sensor, known as T25, recently became the first 3D-printed part certified by the U.S. Federal Aviation Administration (FAA) to fly inside GE commercial jet engines.
According to GE:
GE Aviation is currently working with Boeing to retrofit more than 400 GE90-94B jet engines – some of the world’s largest and most powerful – with the 3D printed part. The GE90 family of engines powers Boeing’s 777 planes.
GE is also developing 3D-printed fuel nozzles and other parts for the GE9X engine for Boeing’s new 777X aircraft. The GE9X will be the largest jet engine ever built.
GE Aviation’s total backlog now exceeds $135 billion for both equipment and services, and the value of the backlog has grown by a quarter over the last two years alone.
