Effect of bimodal powder blends on part density and melt pool fluctuation in laser powder bed fusion

The final part density in laser powder bed fusion is influenced by the powder particle size distribution. Too fine powders are not spreadable, and too coarse powders cause porosity. Powder blends, especially bimodal ones, can exhibit higher …
