A soluble material for three-dimensional modeling, which is used as a raw material of a support material for supporting a three-dimensional object when the three-dimensional object is produced, using a 3D printer of a FDM system, includes a polyester resin including one or more aromatic dicarboxylic acid monomer units A with a sulfonate group, one or more dicarboxylic acid monomer units B without a sulfonate group, and one or more diol monomer units. The proportion of the aromatic dicarboxylic acid monomer unit(s) A in the total of all dicarboxylic acid monomer units is from 10 to 70 mol %. The soluble material has hygroscopicity resistance while the material is large in dissolution rate into any neutral water and removable speedily from a precursor of the three-dimensional object without using any aqueous strong alkaline solution.

A copolyester, comprising structural units represented by [I], [II], [III] and [IV]. The number of structural units represented by [III] is 1-99% of the number of structural units represented by [I], and the number of structural units represented by [IV] is 0-99% of the number of structural units represented by [I]. Also provided are a preparation method therefor and an application thereof. Because an introduced high-temperature self-crosslinking group and an ion group can improve the melt viscosity and the melt intensity during burning of a copolyester, and effectively enhance the char-forming capability of the copolyester, the copolyester exhibits excellent flame retardance and anti-dripping performance. The preparation process for the copolyester is mature, convenient to operate, and easy to control and apply to industrial production.
