Pratt & Whitney joins with ST for aero-engine component

Pratt & Whitney revealed the industrialization of the use of 3D-printing for an aero-engine component. The 3D-printed part is projected to be part of the repair process by mid-2020 at Pratt & Whitney’s repair specialist in Singapore, Component Aerospace Singapore.

This innovative approach was the result of an integrative effort between Pratt & Whitney’s engineering experts, its repair specialist Component Aerospace Singapore, in collaboration with the Land Systems arm of ST Engineering, to deliver faster and flexible repair solutions to support Pratt & Whitney engines.

The 3D-printed aero-engine component taps the production-level 3D capabilities at ST Engineering and strong domain knowledge in metal printing via a controlled process operationalized by Pratt & Whitney. This 3D printed part will first be used in a fuel system component on one of Pratt & Whitney’s engine models. The alternative material solution offers an added advantage of reducing dependency on current material supply from conventional fabrication processes such as forging and casting.

Pratt & Whitney’s Component Aerospace Singapore is a repair specialist providing engine part repair for combustion chambers, fuel system components, tubes, ducts and manifolds for the V2500 and PW4000 engines
