A copolymer for use in 3D printing includes about 1 to about 30 mole percent of a diacid monomer unit, a diol monomer unit, and a terephthalate monomer unit, the copolymer having a glass transition temperature (Tg) in a range from about 50 DEG C. to about 95 DEG C. 本发明公开了种用于3D打印中的共聚物，其包含约1至约30摩尔％的二酸单体单元、二醇单体单元和对苯二甲酸酯单体单元，所述共聚物具有在约50℃至约95℃范围内的玻璃化转变温度(T)。
