Beschreibung
Zusammenfassung:	Provided are: a resin powder mixture which contains a polyarylene sulfide resin powder and has a gas generation amount of 0.25 wt% or less, a melt flow rate of 5-75 g/10 min and an average particle diameter of 1-100 µm; a method for producing same; and a method for producing a three-dimensional molded product using this resin powder mixture. By using this resin powder mixture, it is possible to obtain a three-dimensional molded product which has few voids and exhibits excellent tensile strength. L'invention concerne un mélange de poudre de résine qui contient une poudre de résine de sulfure de polyarylène de quantité de gaz généré inférieure ou égale à 0,25% en masse, d'indice de fluidité à chaud supérieur ou égal à 5g/10min et inférieur ou égal à 75g/10min, et de diamètre particulaire moyen supérieur ou égal à 1µm et inférieur ou égal à 100µm. L'invention concerne également un procédé de fabrication de ce mélange de poudre de résine, et un procédé de fabrication d'objet moulé tri-dimensionnel mettant en uvre ce mélange de poudre de résine. La mise en uvre du mélange de poudre de résine de l'invention permet d'obtenir un objet moulé tri-dimensionnel présentant peu de vides et d'une excellente résistance à la traction.
