Zusammenfassung:To provide a powder material for three-dimensional molding suitable for manufacturing a three-dimensional molded product by a laser sintering type three-dimensional printer.SOLUTION: A powder material for three-dimensional molding contains a resin powder and a nanofiber, and has an average particle size of 30 to 80 μm and the nanofiber content of 2 to 15 wt.%. The resin powder includes, for example, a thermoplastic resin. The nanofiber is, for example, cellulose nanofiber. In the powder material, in a volume-based particle size distribution measured based on a laser diffraction/scattering method, a cumulative frequency of particle diameter of less than 38 μm may be 10% or more.SELECTED DRAWING: Figure 2 【課題】レーザー焼結式３Ｄプリンターによる三次元造形物の製造に適した三次元造形用粉体材料を提供する。【解決手段】樹脂粉体とナノファイバーとを含み、平均粒子径が３０〜８０μｍであり、ナノファイバーの含有量が２〜１５重量％である三次元造形用粉体材料とする。樹脂粉体は、例えば、熱可塑性樹脂を含む。ナノファイバーは、例えば、セルロースナノファイバーである。この粉体材料では、レーザー回折・散乱法に基づいて測定された体積基準の粒度分布において、粒子径３８μｍ未満の累積頻度が１０％以上であってもよい。【選択図】図２
