The method for manufacturing 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 3D printer of a fused deposition modeling system, comprising a kneading step of kneading raw materials of the soluble material for three-dimensional modeling by a twin screw extruder having a screw configuration in which a ratio of a total length K of kneading discs to a total length L of an effective screw is 0.20<K/L<0.70 and in which a temperature Tmix of the raw materials of the soluble material for three-dimensional modeling in the kneading step and a glass transition temperature Tg of a base polymer contained in the raw materials of the soluble material for three-dimensional modeling satisfy a formula Tg+80(° C.)<Tmix<Tg+200(° C.).
