•Original valve was made from a steel casting.
•Obsolescence issue made it impossible to get spare valves.
•Helicopter owner turned to 3D Wave USA to provide a solution.
•The original part was 3D-modeled from original design data.
•A plastic prototype was 3D-printed to validate CAD geometry and manufacturing approach.
•End-use part was manufactured from 17-4 SS powder using EOS M290 laser sintering machine.
•The printed valve was CT-scanned for internal cavities and was deemed acceptable after some final finishes.
•The 3D-printed part was more efficient due to integrated fuel flow paths which the additive manufacturing technology made possible.
