Abstract
A method of printing a 3D part with an additive manufacturing system includes printing a first portion of the part and pre-heating the first portion of the part along an upcoming tool path to a temperature at or above a material-specific bonding temperature and below a degradation temperature of the material. Material is extruding material onto the first portion along the pre-heated tool path while the temperature along the part surface remains at or above a material-specific bonding temperature and below the degradation temperature of the material thereby forming a newly extruded road. The method includes cooling the newly extruded road along the pre-heated tool path to remove heat imparted by the preheating step such that a thermally stable temperature is reached, wherein the preheating, extruding and cooling is performed in less than ten seconds.
