| 20160375636 | METHOD FOR PRINTING THREE-DIMENSIONAL PARTS WITH CRYSTALLIZATION KINETICS CONTROL - A method for printing a three-dimensional part with an additive manufacturing system, which includes providing a part material that compositionally has one or more semi-crystalline polymers and one or more secondary materials that are configured to retard crystallization of the one or more semi-crystalline polymers, where the one or more secondary materials are substantially miscible with the one or more semi-crystalline polymers. The method also includes melting the part material in the additive manufacturing system, forming 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 an annealing temperature that is between a glass transition temperature of the part material and a cold crystallization temperature of the part material. | 12-29-2016 |
