PROBLEM TO BE SOLVED: To provide powder for lamination molding capable of improving a strength of a molded article by enhancement of flowability.SOLUTION: There is provided powder for lamination molding used for lamination molding. The powder for lamination molding contains a large-particle component having a coating layer of a thermoplastic resin, and a middle-particle component and a small-particle component having no coating layer. An average particle diameter D1 of the large-particle component is 20 μm or more, an average particle diameter D3 of the small-particle component is 0.5 μm or less, and a relationship between the average particle diameter D1 of the large-particle component and an average particle diameter of D2 of the middle-particle component satisfies 1<(D1/D2)<3.SELECTED DRAWING: Figure 1
【課題】流動性が高められて造形物の強度を向上させ得る積層造形用粉体を提供すること。【解決手段】本発明により、積層造形に用いるための積層造形用粉体が提供される。この積層造形用粉体は、熱可塑性樹脂のコーティング層を有する大粒子成分とコーティング層を有しない中粒子成分と小粒子成分とを含む。大粒子成分の平均粒径Ｄ501が２０μｍ以上であり、小粒子成分の平均粒径Ｄ503が０．５μｍ以下であり、かつ大粒子成分の平均粒径Ｄ501と中粒子成分の平均粒径Ｄ502との関係が１＜（Ｄ501／Ｄ502）＜３を満たす。【選択図】図１
