POWDER FOR LAMINATION MOLDING
To provide a powder for lamination molding which has appropriate fluidity that achieves both good construction property to form a uniform powder layer and shape stability to maintain a shape from the application of a binder to a sintering process, and an appropriate bulk density to allow the binder to penetrate between powder materials and to achieve a low shrinkage rate during sintering.SOLUTION: A powder for lamination molding that is an inorganic oxide powder has a D10 of 1.0 to 4.0 μm, a D50 of 5.5 to 9.0 μm, a D90 of 20.0 to 40.0 μm, and a volume ratio of particles having a particle size of 16.8 to 60.0 μm of 15.0 to 22.0 vol.%.SELECTED DRAWING: None
【課題】均一な粉末層を形成し得る良好な敷設性と、バインダー適用から焼結処理までの間に形状を維持できる形状安定性とを両立する適度な流動性、及び粉末材料間にバインダーが入り込むことができ、かつ、焼結時の低収縮率を実現する適度なかさ密度を有する積層造形用粉末の提供。【解決手段】無機酸化物粉末である積層造形用粉末であって、Ｄ１０が１．０～４．０μｍであり、Ｄ５０が５．５～９．０μｍであり、Ｄ９０が２０．０～４０．０μｍであり、粒径１６．８～６０．０μｍの粒子の体積割合が１５．０～２２．０体積％である積層造形用粉末。【選択図】なし
