AbstractLaser consolidation (LC) is a laser-cladding-based novel manufacturing process that produces net-shape functional components directly from a CAD model. As an alternative to conventional machining processes, the LC process builds complete net-shape functional parts of features on existing parts by adding instead of removing material. In this paper, laser consolidation of Waspaaloy and IN-718 alloys is demonstrated. The LC process successfully built metallurgically sound Waspaloy and IN-718 alloy samples. The microstructures of as-consolidated and heat-treated LC Waspaloy and IN-718 materials were examined. Their tensile properties were evaluated and compared with reference data. In addition, several samples that are difficult to make using conventional manufacturing technologies were produced using LC process to demonstrate its capacity.
