Abstract: The present invention is a three-dimensional-modeling soluble material to be used as a material of a support member for supporting a three-dimensional object when the three-dimensional object is produced with a 3D printer that employs a fused deposition modeling method. The three-dimensional-modeling soluble material contains a polyester resin comprising: an aromatic dicarboxylic acid monomer unit A having a sulfonic acid base; a dicarboxylic acid monomer unit B that does not have a sulfonic acid base; and a diol monomer unit, wherein the proportion of the aromatic dicarboxylic acid monomer unit A in the total of all dicarboxylic acid monomer units is 10 to 70 mol %. The present invention can provide a three-dimensional-modeling soluble material to be used for a support member, which material is suitable for production of a three-dimensional object by the FDM method, has moisture-absorption resistance, has a high rate of dissolution in neutral water, and can be quickly removed from a three-dimensional object precursor without using a strong alkali aqueous solution.

Abstract: The soluble material for three-dimensional modeling of the present invention is a soluble material for three-dimensional modeling that is used as a material of a support material that supports a three-dimensional object when manufacturing the three-dimensional object with a fused deposition modeling type 3D printer. The soluble material for three-dimensional modeling contains at least one polymer and at least one filler. In the soluble material for three-dimensional modeling, the filler is a fibrous filler having a fiber length of 0. 02 µm to 1, 000 µm and a fiber diameter of 0.0001 µm to 20 µm and/or a flat filler having a particle size of 0.1 µm to 20 µm and a thickness of 0.01 µm to 10 µm. The content of the filler is 0.01 part by mass to 200 parts by mass with respect to 100 parts by mass of the polymer. According to the present invention, foaming and a decrease of the accuracy of a three-dimensional object can be suppressed even when the soluble material for three-dimensional modeling is used in manufacture of the three-dimensional object with a 3D printer after being exposed to high humidity.
