In this segment, the speaker highlights a flagship example of how emerging additive manufacturing technologies can unlock major value in aerospace. Historically, GE’s jet engine fuel injector nozzle was a complex assembly of twenty titanium components that required extensive brazing, welding, and the use of jigs and fixtures. By leveraging cobalt‑chromium metal 3D printing, GE has produced a single, consolidated part that replaces the entire twenty‑piece assembly, dramatically simplifying production and showcasing the high‑value potential of metal additive manufacturing.

But I think the classic example of where new technologies create a huge opportunity is the GE jet engine nozzle. This is a nozzle to inject fuel into the turbines. That fuel injector in the past was 20 pieces of titanium that were brazed and welded together that was very complex, that required jigs and fixtures. And now that actually, targeted a very high-value-add application that with cobalt chromium, they've been actually able to 3D print a metal part that replaces— one part replaces 20 parts for that nozzle.
