RESIN POWDER FOR SOLID FREEFORM FABRICATION

Resin powder for solid freeform fabrication includes powder A having a substantially flat portion and the ratio (Y/X) of from 0.5 to 1.0, where X and Y respectively represent the diameter of a circle having an area equivalent to a projected area of the resin powder and the diameter of a circle havin...

Zusammenfassung:	Resin powder for solid freeform fabrication includes powder A having a substantially flat portion and the ratio (Y/X) of from 0.5 to 1.0, where X and Y respectively represent the diameter of a circle having an area equivalent to a projected area of the resin powder and the diameter of a circle having an area equivalent to a projected area of the flat portion of the powder A in a projected image of the resin powder obtained by SEM, wherein the ratio of the number average surface diameter Dy of the powder A to the number average particle diameter Dn of the resin powder is from 0.50 to 1.50, where Dy represents the average on number basis of Y A , which is the diameter of a circle having an area equivalent to a projected area of the flat portion of the powder A in a projected image of the resin powder.
