Abstract

The 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 includes at least one copolymer comprising a specific hydrophilic monomer unit and a specific hydrophobic monomer unit. The present invention has a glass transition temperature suitable for the FDM system, has a high dissolution rate in an alkaline aqueous solution, can be quickly removed from a precursor of a three-dimensional object, and makes it possible to suppress or reduce damage to a three-dimensional object.
