In this doctoral thesis, the influence of increased particle size distributions (PSD) of up to 20-125 μm in laser-based powder bed fusion (LPBF) for aluminium and titanium alloys is investigated. Larger PSDs are generated and analysed regarding their powder properties, LPBF behaviour, required process parameter adjustments, and resulting mechanical properties. By adapting process parameters, the processability of Ti-6Al-4V is ensured, achieving mechanical properties comparable to industrial standards. Atomization yield increases by 44 %, while material costs are reduced by 20 %.
