Objects can be produced using an additive manufacturing process. The objects can include a plurality of layers of a polymeric material that includes a copolyester ether. The copolyester ether can include units of a diacid component and units of a glycol component. In some implementations, the units of the diacid component can be derived from at least one aliphatic dicarboxylic acid. Further, in some illustrative examples, the units of the glycol component can be derived from an aliphatic glycol and a polyalkylene ether glycol. In some cases, the polymeric material can also include a thermoplastic elastomer and a resin component. 可以使用增材制造法生产物体。该物体可包括包含共聚酯醚的聚合材料的多个层。该共聚酯醚可包含二酸组分单元和二醇组分单元。在些实施方案中，二酸组分单元可衍生自至少种脂族二羧酸。此外，在些示例性实例中，二醇组分单元可衍生自脂族二醇和聚亚烷基醚二醇。在些情况下，该聚合材料还可包含热塑性弹性体和树脂组分。
