On recoated powder quality with a forward rotating flexible roller in laser powder bed fusion of 30 wt% 5 μm SiCp/AlSi10Mg composites

On recoated powder quality with a forward rotating flexible roller in laser powder bed fusion of 30 wt% 5 μm SiCp/AlSi10Mg composites

This paper proposes a new powder recoating mechanism named forward rotating flexible roller (FRFR) which aims to solve the poor powder flowability problem brought by the aggregation effect of the fine particles in the mixed 30 wt% 5 μm SiC and 55 μm AlSi10Mg powder. An initial extrusion force instea...
