    The present invention is a hydraulic composition for an additive manufacturing device. The hydraulic composition includes at least sand, an inorganic bonding material, and polyvinyl alcohol and satisfies conditions (1) and (2). (1) The mass ratio of sand/(inorganic bonding material+polyvinyl alcohol) is 4-12. (2) The mass ratio of polyvinyl alcohol/inorganic bonding material is 0.1-0.4. The hydraulic composition for an additive manufacturing device also preferably satisfies condition (3). (3) The mass ratio of water/(inorganic bonding material+polyvinyl alcohol) is 0.30-1.30.

    本发明为一种增材制造装置用水硬性组合物，该增材制造装置用水硬性组合物至少包含砂、无机粘合材料和聚乙烯醇，其满足下述(1)和(2)的条件。(1)砂/(无机粘合材料+聚乙烯醇)的质量比为4～12；(2)聚乙烯醇/无机粘合材料的质量比为0.1～0.4。此外，本发明优选为方案1所述的增材制造装置用水硬性组合物，其满足下述(3)的条件。(3)水/(无机粘合材料+聚乙烯醇)的质量比为0.30～1.30。
