    Abstract: An additive manufacturing system includes a build chamber with at least first and second side walls and top and bottom walls. A central deformable, thermal insulator has a first edge and a second edge, where a print head carriage is movably retained within the central deformable thermal insulator and is configured to move print heads within a build plane of the build chamber under control of a gantry. The system includes first and second dynamic thermal barriers each having a length between a proximal edge and a distal edge wherein the proximal edge is configured to be secured to the central deformable insulator and a distal edge is configured to be movably retained to the build chamber such that as the print head carriage moves laterally across the build plane, each dynamic thermal barrier moves with the central deformable insulator and print head carriage, and retains its length.

    Abstract: An additive manufacturing system for printing a 3D part includes a build platen and a starter piece supported by the build platen. The starter piece comprises a build surface having a plurality of channels and wherein the build surface has a void fraction due to an open surface area of the channels ranging from about 0.5 to about 0.95. The print head includes a nozzle configured to extrude a molten material in a print plane and wherein the extruded material is configured fill a space between the build surface and the print plane and at least partially fill a portion of the plurality of channels such that a base layer of material is printed having a substantially planar surface upon which a 3D part can be printed along a print axis.

    Abstract: A liquefier assembly for use in an additive manufacturing system, which includes a rigid member having a gap, a liquefier tube operably disposed in the gap, one or more heater assemblies disposed in the gap in contact with the liquefier tube, and configured to heat the liquefier tube in a zone-by-zone manner, preferably one or more thermal resistors disposed in the gap between the rigid member and the heater assemblies, and preferably one or more sensors configured to operably measure pressure within the liquefier tube. The one or more heater assemblies may be operated to provide dynamic heat flow control.

    Abstract: A three-dimensional part printed using an additive manufacturing technique, which includes sets of printed cell layers, each defining an array of hollow cells with wall segments, and sets of printed transition layers, each being disposed between adjacent printed cell layers, where the sets of printed transition layers each comprise sloped walls that diverge from a first portion of the wall segments and that converge towards a second portion of the wall segments to interconnect the hollow cells of adjacent printed cell layers, and where the sloped walls of adjacent printed transition layers have printing orientations that are rotated from each other in a build plane.
