Laser Powder Bed Fusion (PBF-LB) is one of the most important additive manufacturing processes and extremely flexible in terms of geometrical freedom. With regard to the materials to be processed, however, this flexibility is not yet given in PBF-LB. In general, a limited variety of standard alloys is available. Thus, powders for specialized applications are often very expensive. A new approach to expanding the range of materials for additive manufacturing is the powder toolbox principle. Here, different standard powders can be mixed with each other, with elemental powders or other additives, e.g. carbides or nitrides, to produce new alloys and materials. The alloying then takes place in situ during the PBF-LB process.
This presentation will show some examples of how powder blends can be used to adapt and develop materials. In addition, the presentation will show the challenges that still need to be overcome when working with powder blends in the PBF-LB process.
