The primary goal of this research is to develop and demonstrate an integrated digital manufacturing framework that enables transit agencies to reliably produce and manage spare parts using additive manufacturing. Specific objectives include: 1) establishing a digital inventory of validated, AM-ready spare parts for transit vehicles, and 2) demonstrating reverse engineering and 3D printing workflows for difficult-to-procure components.

Intended outputs and outcomes include delivery of a digital inventory system that supports repeatable, on-demand production of additive manufacturing spare parts for transit applications. The research will result in validated polymeric 3D-printed components, supported by documented form-and-fit testing and production parameters. The project will also train transit agency personnel, enabling knowledge transfer and fostering the adoption of advanced digital manufacturing technologies within day-to-day maintenance and operations.
