The present invention is suitable for manufacturing a three-dimensional object by the FDM method, has moisture absorption resistance, has a high dissolution rate in neutral water, and can be quickly removed from a three-dimensional object precursor without using a strong alkaline aqueous solution. A three-dimensional modeling soluble material for a support material that can be provided. A three-dimensional modeling soluble material used as a support material for supporting a three-dimensional object when a three-dimensional object is manufactured by a hot melt lamination type 3D printer, The soluble material contains a polyamide resin, and the polyamide resin has a hydrophilic monomer unit A having a hydrophilic group, a hydrophobic dicarboxylic acid monomer unit B, and a hydrophobic diamine monomer unit C, and all monomers in the polyamide resin The soluble material for three-dimensional modeling, wherein the ratio of the hydrophilic monomer unit A to the total of the units is 2.5 mol% or more and less than 13.5 mol%.
