1. A method for printing a three-dimensional part in a layer-by-layer manner with an additive manufacturing system, the method comprising:
providing a part material compositionally including one or more semi-crystalline polyaryletherketone polymers and one or more amorphous polymers that are configured to retard crystallization of the one or more semi-crystalline polyaryletherketone polymers, wherein the one or more amorphous polymers are substantially miscible with the one or more semi-crystalline polyaryletherketone polymers;
melting the part material in the additive manufacturing system;
printing at least a portion of a layer of the three-dimensional part from the melted part material in a build environment; and
maintaining the build environment at a temperature that is below a cold crystallization temperature of the part material, such that a temperature of the portion of the layer is cooled to a temperature below the cold crystallization temperature while the amorphous polymer retards crystallization of the one or more semi-crystalline polyaryletherketone polymers, such that residual stresses in the portion of the layer are managed to substantially prevent curling.
