Title:
RESIN POWDER MIXTURE, METHOD FOR PRODUCING SAME, AND METHOD FOR PRODUCING THREE-DIMENSIONAL MODEL
Document Type and Number:
WIPO Patent Application WO/2022/163524
Kind Code:
A1
Abstract:
A resin powder mixture prepared by mixing at least (A): a resin powder having an average particle size of more than 1 μm and not more than 100 μm with (B): an inorganic reinforcement material, (A) and (B) having different densities, characterized in that, per 100 parts by weight of (A), the content of (B) is from 1 to 100 parts by weight inclusive, and the density deviation of the resin powder mixture is not more than 0.005. A method for producing the resin powder mixture, and a method for producing a three-dimensional model using the same. Thus, a resin powder mixture having high dispersibility of the inorganic reinforcement material can be obtained. When a three-dimensional model is produced using the resin powder mixture, a high tensile strength can be obtained.
