Our team is conducting both fundamental modeling and processing-related research, and industrially-driven programs aiming at increasing the utilization and service performance of real-scale components fabricated from powder materials.

Our modeling and experimental works aim at defining routes for the fabrication of defect-free AM parts using systems suffering from solidification issues (Al alloys and Superalloys). We are working with an in-house built laser-based powder bed system that has a pulse shaping freedom permitting alloy-specific processing. Concepts such as microsegregation solidification modeling (with experimental validation), pulse firing sequence to maximize productivity while maintaining rapid solidification conditions and powder blend engineering, on the microstructure and properties are studied. Additional work on wire-based laser AM and AM extrusion of high temperature materials are on-going.
