  • Publication number: 20180230274
    Abstract: A method for preparing an aliphatic polyester resin powder includes the steps of a) heat dissolving a crystalline aliphatic polyester resin in an organic solvent to obtain an aliphatic polyester resin solution; b) cooling the aliphatic polyester resin solution to precipitate a solid, thereby obtaining a solid-liquid mixture; c) optionally adding an adjuvant to the solid-liquid mixture and mixing; and d) conducting solid-liquid separation and drying to obtain an aliphatic polyester resin powder suitable for selective laser sintering. The crystalline aliphatic polyester resin powder obtained has good antioxidant property, good powder flowability, moderate size, smooth surface, suitable bulk density, and suitable dispersibility and particle size distribution. The aliphatic polyester resin powder is particularly suitable for selective laser sintering method.
