AEROSPACE manufacturer Pratt & Whitney, a division of United Technologies Corp, unveiled an industrialised process for 3D-printed aero-engine components, developed in collaboration with ST Engineering.

Said to be a first in the maintenance, repair and overhaul (MRO) scene for commercial engines, the process is the result of an integrative effort between Pratt & Whitney’s engineering experts, the company’s repair specialist Component Aerospace Singapore, and ST Engineering’s Land Systems arm. The process tapped ST Engineering’s production-level 3D-printing capabilities and strong domain knowledge in metal printing, and was operationalised by Pratt & Whitney.

The 3D-printed metallic part produced in this initial application will first be used in a fuel system component on one of Pratt & Whitney’s engine models. It is projected to become part of the repair process used by Component Aerospace Singapore by mid-2020.
