  • Hydraulic composition for additive manufacturing device and method of manufacturing casting mold
    Patent number: 11173539
    Abstract: A hydraulic composition for an additive manufacturing device has an excellent initial flexural strength development property and dimensional stability. The hydraulic composition includes 1.5 to 14 parts by mass of a polymer with respect to 100 parts by mass of an inorganic binder. In addition, in a hydraulic composition for an additive manufacturing device, the inorganic binder may contain 50 to 100 mass % of a calcium aluminate with respect to 100 mass % of the entire inorganic binder, and in a hydraulic composition for an additive manufacturing device the inorganic binder, may contain 0 to 50 mass % of rapid hardening cement with respect to 100 mass % of the entire inorganic binder.
