Zusammenfassung:	A three-dimensional printing method is provided. The method comprises selectively fusing a powder within a powder bed, wherein the powder comprises a plurality of polyarylene sulfide microparticles having a volume-based median particle size of from about 0.5 to about 200 micrometers. L'invention concerne un procédé d'impression en trois dimensions. Le procédé comprend la fusion sélective d'une poudre à l'intérieur d'un lit de poudre, la poudre comprenant une pluralité de microparticules de sulfure de polyarylène ayant une taille de particule médiane en volume d'environ 0,5 à environ 200 micromètres.
