摘要： The present invention provides a hydraulic composition for an additive manufacturing device having an excellent initial flexural strength development property and dimensional stability, the hydraulic composition for an additive manufacturing device including: 1.5 to 14 parts by mass of a polymer with respect to 100 parts by mass of an inorganic binder. In addition, the present invention preferably provides a hydraulic composition for an additive manufacturing device in which the inorganic binder contains 50 to 100 mass % of a calcium aluminate with respect to 100 mass % of the entire inorganic binder, and more preferably provides a hydraulic composition for an additive manufacturing device in which the inorganic binder contains 0 to 50 mass % of rapid hardening cement with respect to 100 mass % of the entire inorganic binder.
