AbstractLaser consolidation is a novel rapid manufacturing process that produces a net-shape functional complex part layer by layer directly from a CAD model without any moulds or dies. This process uses a laser beam to melt a controlled amount of injected powder on a base plate to deposit the first layer and on previous passes for the subsequent layers. As opposed to conventional machining processes, this computer-aided manufacturing (CAM) technology builds complete net-shape functional parts or features on an existing component by adding instead of removing material. The LC samples also show very good surface finish and dimensional accuracy. Surface finish of the order of 1~2 µm (Ra) is obtained on as-consolidated IN-625. In this paper, laser consolidation process will be introduced, the functional properties of the laser-consolidated IN-625 and Ti-6Al-4V alloys will be described, and two applications of the process will be discussed.
