    Abstract: A method of printing a part in an additive manufacturing system includes printing a support structure for the part, printing a boundary surrounding the support structure, and printing the part on the support structure. An additive manufacturing system for printing a three-dimensional part includes a transfer medium configured to receive and transfer imaged layers of a thermoplastic-based powder for a boundary, a thermoplastic-based powder for a support, and a thermoplastic-based powder for the part from at least two imaging engines, a heater configured to heat the imaged layers on the transfer medium to at least a fusion temperature of the thermoplastic-based powder, and a layer transfusion assembly including a build platform, the layer transfusion assembly being configured to transfuse the heated layers in a layer-by-layer manner onto the build platform to print the three-dimensional part.

    Abstract: A method for printing a 3D part in a layer-wise manner includes providing a pool of polymerizable liquid in a vessel over a build window and positioning a downward-facing build platform in the pool, thereby defining a build region above the build window. The method includes selectively curing a volume of polymerizable liquid in the build region by imparting electromagnetic radiation through the build window to form a printed layer of the part adhered to the build platform and actively cooling the build window to remove energy imparted by the electromagnetic radiation and the polymerization reaction of the polymerizable liquid such that the printed layer is between about 1° C. and about 30° C. below an average part temperature prior to raising the print layer and printing the next layer.

    Abstract: A 3D printer is configured to print a 3D part. The 3D printer includes a print head carried by a head gantry and configured to operably move the print head along planar tool paths. The 3D printer includes at least one head gantry actuator coupled to the head gantry and configured to move the print head in a plane and a print head actuator coupled to the print head and configured to move the print head in a direction substantially orthogonal to the plane. A sensor is fixedly mounted to the print head and configured to output a first signal that is directly or indirectly related to an acceleration of the print head, and a gyroscope is fixedly mounted to the print head and configured to output a second signal related to a rotational position of the print head. The 3D printer includes a controller configured to determine a rotational position error of the print head relative to a predetermined position based on the first signal and the second signal and to output one or more signals to the at least one head gantry actuator and/or the print head actuator to compensate for the rotational position error of the print head.
