In the project, a methodology is being developed which aligns the properties of PBF-LB/M components to specific requirement profiles by means of processing powder blends and in-situ alloy formation in the LPBF melt bath. With a limited selection of commercially available starting powders, numerous new alloys with a tailored property spectrum can be produced very flexibly and inexpensively using the ''LPBF powder kit'' principle.
