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 is printed using an additive manufacturing technique. The three-dimensional part includes an outer wall having an outer surface defining a shape of a part and in interior surface defining an interior cavity. The part includes a plurality of first sections having a plurality of printed layers, each printed layer of the first section having a plurality of wall segments that form triangle shaped cells wherein each of the plurality of first sections are attached to the interior surface of the outer wall. The part includes a plurality of second sections having a plurality of printed layers, each printed layer of the second section having a plurality of wall segments that form hexagram shaped cells of hexagons and triangles, wherein each of the plurality of second printed sections are attached to the interior surface of the outer wall and wherein the first and second sections are in an alternating pattern, wherein when adjacent printed layers of the first and second sections are printed a wall segment of a cell defining a triangle bisect the hexagon shaped cell.

Abstract: A coil assembly comprising a coil of a strand-based material retained in a figure-8 configuration, and having an inner layer and an outer layer, where the inner layer of the coil defines a core region of the coil, and where the coil is configured to unwind loop by loop beginning from the inner layer and moving towards the outer layer as the strand-based material is drawn through a payout hole. The coil assembly also comprises a permeable hub configured to reduce payout entanglement of the strand-based material.
