Abstract: A method for additive manufacturing a part using fused deposition modeling 3D printing technology includes projecting a laser image from one or more laser emitters onto a previously printed bead or beads of thermoplastic material forming a portion of the part, along a tool path for a next bead in a subsequent part layer. The laser image has a width of between about 50% to 75% of a commanded beadwidth of the next bead, and is moved along a tool path that is generally transverse to the width thereof, to thereby selectively irradiate and heat the previously printed thermoplastic material to at least a bonding temperature thereof but below a degradation temperature. A bead of thermoplastic material is extruded from an extrusion head and deposited along the tool path while at least a top surface portion of the irradiated material remains at or above its bonding temperature, so that strong adhesion occurs between part layers.

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.

Abstract: A method for 3D printing a part with an additive manufacturing system includes printing a first portion of a part in a layerwise manner and analyzing a topology of the first portion of the part. The method includes determining a tool path for printing a second portion of the part on a surface of the first portion of the part, and pre-heating the first portion of the part along the tool path as a function of the topological analysis of the first portion of the part. The method includes printing the second portion of the part along the tool path.

Abstract: A method of additive manufacturing comprises operating an additive manufacturing system for fabricating a multiplicity of objects, while acquiring a set of images during fabrication of each of the objects. For each object, a respective set of images is analyzed to identify fabrication irregularities, and a fabrication score is generated based on the irregularities. The multiplicity of objects is clustered according to the fabrication scores into at least two clusters.
