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.
