Abstract: The present disclosure relates to a method involving a substrate having an interface layer, wherein the interface layer (IL) forms only an upper surface portion of the substrate, and a feedstock material (FM) placed on the IL. The method involves using a laser system to generate first and second beam components providing first and second power flux levels, respectively, where the second level is greater than the first.
