摘要： 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.

摘要： A consumable material for use in an extrusion-based digital manufacturing system, the consumable material comprising a length and a cross-sectional profile of at least a portion of the length that is axially asymmetric. The cross-sectional profile is configured to provide a response time with a non-cylindrical liquefier of the extrusion-based digital manufacturing system that is faster than a response time achievable with a cylindrical filament in a cylindrical liquefier for a same thermally limited, maximum volumetric flow rate.

摘要： A magnetically throttled liquefier assembly for use in an additive manufacturing system and configured to heat a metal-based alloy to an extrudable state includes an array of magnets to generate a magnetic field in order to induce a viscosity in the heated metal-based alloy and to control the flow rate of the heated metal-based alloy through the liquefier for extrusion and the building of a three-dimensional object with the metal-based alloy.

摘要： 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.

摘要： In a method for printing a three-dimensional (3D) parts with an additive manufacturing system, a developed layer of an electrically charged powder material is produced on a transfer medium using an electrophotographic (EP) engine. The transfer medium and the developed layer are fed in a feed direction. A position of the developed layer on the transfer medium is detected using a first sensor having a first output that indicates the position. A position of a moveable build platform is adjusted relative to the transfer medium to reduce one or more overlay errors between the developed layer and an intermediate build surface of a three-dimensional structure retained on the moveable build platform based on the first output. The developed layer is transferred to the intermediate build surface using a pressing element.
