GE Aviation has announced that its 3D printed sump cover has received Engineering Change Proposal (ECP) approval from the US Air Force (USAF), making it the first jet engine part fabricated with metal 3D printing to be qualified by any Department of Defense body.

The F110 component was made as a part of the Pacer Edge program established by the USAF and GE. This pathfinder program is dedicated to scaling technology determined to be necessary for the operation and sustainment of aircraft. This includes spare parts, where 3D printing has been identified as possibly being a powerful tool to create out-of-production replacements. The F-15SG is powered by the F110-GE-129 for the Republic of Singapore Air Force.

Given the conglomerate’s track record with the LEAP fuel nozzle and other parts 3D printed for the GE9X, the company was an ideal partner for the program.
