1. A ribbon liquefier for use in an extrusion-based digital manufacturing system having a drive mechanism and a heat transfer component, the ribbon liquefier comprising:

  • an outer liquefier portion configured to receive thermal energy from the heat transfer component; and

    a channel at least partially defined by the outer liquefier portion, the channel having dimensions that are configured to receive a ribbon filament, wherein 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, and wherein the dimensions of the slot 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.
