Challenge
The nozzle required 20 separately welded parts with intricate internal cooling passages. Traditional manufacturing was costly, time-intensive, and introduced failure-prone weld joints.
Solution
Redesigned as a single monolithic cobalt-chrome part via laser PBF at the Auburn, Alabama facility — the industry's first mass-production site for AM aircraft engine parts. Complex internal cooling channels impossible by conventional means were directly embedded.
Outcomes
- 0125% weight reduction
- 0220 → 1 part consolidation
- 035x vs welded design durability improvement
Technologies
Laser Powder Bed Fusion
