Beschreibung
Zusammenfassung:	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 process comprises applying an amount of energy to a portion of a first amount of a powder comprising a polymeric material including the copolyester to form a first layer of an object; providing a second amount of the powder and applying an additional amount of energy to a portion of the second amount of the powder to form a second layer of the object, the second layer being disposed adjacent to and contacting the first layer. 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.
