ADDITIVE MANUFACTURING POWDER AND METHOD OF MANUFACTURING THE SAME

摘要

Additive manufacturing powder contains a core-shell type particle containing a core particle comprising a first binder resin and a filler and a shell present on the surface of the core particle. The shell contains a second binder resin. The powder has a particle size distribution Dv/Dn of 1.5 or less and an average circularity of from 0.800 to 0.980, the average circularity being represented by the following relation:;Average circularity=(a perimeter of a circle having the same area as a projected image of a particle)/(the perimeter of the projected image of the particle)×100.
