Powder Mixture, Method For Producing Same, Powder Composition And Method For Producing Three Dimensional Model

Abstract: A powder mixture which contains a polybutylene terephthalate resin and a polycarbonate resin, and which is characterized in that: the average particle diameter thereof is more than 1 µm but 100 µm or less; the homogeneity thereof is 4 or less; the melting point thereof is more than 220°C; and the difference between the melting point thereof and the crystallization temperature thereof is 60°C or more. A powder composition which is characterized by containing inorganic fine particles that have an average particle diameter of 20-500 nm at a ratio of 0.1-5 parts by weight relative to 100 parts by weight of the powder mixture. The present invention efficiently provides a polybutylene terephthalate resin powder which is suitable as a material powder for the production of a three-dimensional model by means of a powder sintering 3D printer.
