A few weeks ago General Electric announced that the FAA (U.S. Federal Aviation Administration) cleared their first 3D printed part to fly. The fist-sized T25 housing for a compressor inlet temperature sensor was fabricated by GE Aviation and will be retrofitted to over 400 GE90-94B jet engines on Boeing 777 aircraft.
The laser sintered housing protects the compressor inlet temperature sensor’s fine electronics from icing and damaging air pressure inside the jet engine. Certification means that this part is now suitable to be mounted into commercial jet engines from GE.
GE is currently partnering with Boeing to install this new part in over 400 of its GE90-94B engines used on the new high-tech Boeing 777 aircraft.

Naturally GE Aviation is not stopping on a single part. Here is a video from GE Aviation on their next part to be installed into LEAP jet engines, the 3d printed fuel nozzle. This 3d printed part is five times as durable as regularly produced one, 25% lighter, runs cooler because of internal cooling structures, only one part instead of 18.
GE report states
We got the final design last October, started production, got it FAA certified in February, and will enter service next week. We could never do this using the traditional casting process, which is how the housing is typically made.Jonathan Clarke, program manager GE Aviation

Hi Lav Radis,
Thanks for a awesome post. I need some information about How much would be cost to buy a 3D Printer?
Can you give me some good information about it. THANKS
Edward Burg says
Could you send information on the equipment used to produce these parts?
Regards

Interesting read! I’m also interested to know how much I can get a 3d printer for?
thanks!

Hi Lav Radis,
It is great news that GE Aviation gets FAA Certification for First 3D Printed Jet Engine Part.
Would you please describe little bit more what is the future of 3D printing on Jet Engine?
Thank you for nice post.
Regards.

This is a great way to prototype since the cost is low and ability to go from design to part is exponentially faster than creating molds.
