Abstract:
A hydraulic composition for an additive manufacturing device, the hydraulic composition containing at least sand, an inorganic binder, and polyvinyl alcohol, wherein the hydraulic composition for an additive manufacturing device satisfies conditions (1) and (2).
(1) The mass ratio of sand/(inorganic binder+polyvinyl alcohol) is 4 to 12.
(2) The mass ratio of polyvinyl alcohol/inorganic binder is 0.1 to 0.4.
The hydraulic composition for an additive manufacturing device also preferably satisfies condition (3).
(3) The mass ratio of water/(inorganic binder+polyvinyl alcohol) is 0.30 to 1.30.
