Zusammenfassung:The soluble material of the present invention for three-dimensional modeling is a soluble material, for three-dimensional modeling, which is used as a raw material of a support material for supporting a three-dimensional object when the three-dimensional object is produced, using a 3D printer of a FDM system. This soluble material comprises a polyester resin comprising one or more aromatic dicarboxylic acid monomer units A with a sulfonate group, one or more dicarboxylic acid monomer units B without a sulfonate group, and one or more diol monomer units; and the proportion of the aromatic dicarboxylic acid monomer unit(s) A in the total of all dicarboxylic acid monomer units is from 10 to 70 mol%. The present invention can provide a soluble material for three-dimensional modeling which is used for a support material and which is suitable for the production of a three-dimensional object by use of an FDM system, and has hygroscopicity resistance while the material is large in dissolution rate into any neutral water and removable speedily from a precursor of the three-dimensional object without using any aqueous strong alkaline solution.
