The present invention is a soluble material for three-dimensional molding that is used as a material of a support member that supports a three-dimensional object when the three-dimensional object is produced using a fused-deposition 3D printer, wherein said soluble material for three-dimensional molding comprises a hydrophilic-group-containing thermoplastic resin, and an organic salt compound represented by general formula (I). (R 1 - SO 3 n - ) n X n+ (I) According to the present invention, it is possible to minimize any reduction in accuracy of a three-dimensional object when the three-dimensional object is produced using a fused-deposition 3D printer, and it is possible to provide a soluble material for three-dimensional molding for use in a support member, said soluble material having a high rate of dissolution in neutral water and being capable of being quickly removed from a precursor of the three-dimensional object without the use of a strong alkali aqueous solution. |
