Abstract: 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.

Abstract: A ribbon liquefier comprising an outer liquefier portion configured to receive thermal energy from a heat transfer component, and a channel at least partially defined by the outer liquefier portion, where the channel has dimensions that are configured to receive the ribbon filament, and where the ribbon liquefier is configured to melt the ribbon filament received in the channel to at least an extrudable state with the received thermal energy to provide a melt flow. The dimensions of the channel are further configured to conform the melt flow from an axially-asymmetric flow to a substantially axially-symmetric flow in an extrusion tip connected to the ribbon liquefier.

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.
