Abstract: A liquefier assembly for use in an additive manufacturing system to print three-dimensional parts, which includes an upstream pressure-generating stage and downstream flow-regulating stage. The upstream pressure-generating stage includes a drive mechanism, a liquefier configured to melt a consumable material receive from the drive mechanism to produce a molten material in a pressurized state. The downstream flow-regulating stage includes a gear assembly having a casing assembly and a pair of gears disposed within the interior cavity and engaged with each other to regulate a flow of the pressurized molten material through the gear assembly for controlled extrusion.

Abstract: A method and system for printing a three-dimensional part, which includes producing a developed layer of a part material with one or more electrophotography engines of an additive manufacturing system, transferring the developed layer from the one or more electrophotography engines to a transfer assembly of the additive manufacturing system sintering the developed layer at the transfer assembly to produce a sintered contiguous film, cooling the sintered contiguous film down to a transfer temperature, and pressing the cooled sintered contiguous film into contact with an intermediate build surface of the three-dimensional part with a low applied pressure.

Abstract: A method and system for printing a three-dimensional part, which includes printing a plurality of successive layers of the three-dimensional part with the additive manufacturing system based on bitslices in a bitslice stack, measuring surface heights of the successive layers after each of the successive layers are printed, determining differences between the measured surface heights and predicted stack heights of the bitslices, identifying one or more topographical error regions based on the determined differences, and modifying the bitslice stack to compensate for the one or more topographical error regions.
