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: An additive manufacturing system configured to a 3D print using a metal wire material includes a drive mechanism configured to feed the metal feedstock into an inlet tube and a liquefier. The liquefier has a chamber configured to accept the metal feedstock from the inlet tube. The metal feed stock is heated in the chamber such that a melt pool is formed in the chamber. The liquefier has an extrusion tube in fluid communication with the chamber, the extrusion tube having a length (L) and a diameter (D) wherein the ratio of length to diameter (L/D) ranges from about 4:1 to about 20:1. The system has a platen with a surface configured to accept melted material from the liquefier, wherein the platen and the liquefier move in at least three dimensions relative to each other. The system includes a regulated source of pressurized inert gas flowably coupled to the liquefier and configured to place a controlled positive pressure onto the melt pool sufficient to overcome the resistance of the extrusion tube such that a part may be formed by the extrusion of the liquidus metal along toolpaths defined by the relative motion of the liquefier and the platen.

Abstract: A rotary additive manufacturing system for producing 3D parts in a layer-wise manner includes a silo support, a tool support, a plurality of silos, and a part developer. The tool support overlays a first side of the silo support, and is configured to rotate about a central axis relative to the silo support. The silos are each attached to the silo support and extend along the central axis from a second side of the silo support that is opposite the first side. The part developer is supported by the tool support, and is configured to build a 3D part within each of the silos in a layer-by-layer manner during rotation of the tool support relative to the silo support.

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.
