The present invention relates to a three-dimensionally shapable soluble material used as a material for a support material for supporting a three-dimensional object by a 3D printer of a thermal melt lamination system, wherein an aromatic dicarboxylic acid monomer unit A having a sulfonic acid group , A dicarboxylic acid monomer unit B having no sulfonic acid group, and a diol monomer unit, wherein the ratio of the aromatic dicarboxylic acid monomer unit A to the total of all the dicarboxylic acid monomer units is from 10 to 70 mol% And a polyester resin which is a three-dimensional molding material. INDUSTRIAL APPLICABILITY According to the present invention, it is possible to rapidly remove a three-dimensional object precursor without using a strong alkaline aqueous solution, which is suitable for the production of a three-dimensional object by the FDM method, has a hygroscopic property, It is possible to provide a three-dimensional shaping soluble material for a supporting material. |
