In laser powder deposition, a laser beam coming from a nozzle acts as a heat source. The beam melts blown powder (supplied by the same or different nozzle) or wire (fed by the different nozzle). By moving the nozzle parallel to a fixed substrate (or the substrate parallel to a fixed nozzle), a melting point becomes a line. By creating such lines as per the design of a first layer, a physical layer is made. By moving the nozzle up (or the substrate down), space is created to accommodate second to-be-fabricated layer—this step, followed by melting, is repeated to fabricate the second layer and so on. The process has variations due to variations in nozzle, feedstock, position of the nozzle, and laser-material interaction. Coaxial continuous, coaxial discrete, and off-axial powder deposition types are practiced.
