Powder modification for laser-based additive manufacturing. (a) Laser-generated tungsten carbide nanoparticles (NPs) adsorbed on tool steel powders (b) Ag NPs adsorbed on ZnO powders (c)& (d) Laser-fragmented Y2O3 NPs adsorbed on stainless steel (e) Shape memory alloy structure built by micro laser sintering of NiTi powder

Project A11 will study the way for i) mechanically stable, permanent magnets built under material resource efficient conditions in PBF-LB and ii) an expansion of the digital data twin by adding a material vector to gain a 3D compositional reconstruction of the printed as-build parts. Processing condition can be tuned while monitoring in-situ the chemical composition to find a sweet spot towards dense parts with improved hysteresis. The numerical (A06), experimental magnetic (A10, A12), and microstructural characterization (A08, Z01, Z02, A03) will be performed.
