The fist-sized piece of silver metal that houses the compressor inlet temperature sensor inside a jet engine is a part that’s bit obscure even for many aviation aficionados. Starting now, however, it’s becoming a symbol of one of the biggest changes sweeping jet engine design.
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.

The T25 housing may be the first 3D printed part to fly on a commercial engine, but you can be sure it won’t be the last. The ability to make novel interior geometries and its flexibility when it comes to making low volume parts pretty much assures 3D printing will become fairly common in future aircraft.
