Abstract: A consumable assembly for supplying filament to a 3D printer having two or more receptacles having different geometric configurations, the 3D printer builds parts by material extrusion. The consumable assembly includes a container configured to retain a supply of a first filament, and a first filament guide tube having a length, the first filament guide tube having an inlet end attached to the first container and an outlet end, The consumable assembly includes a key having a geometric configuration allowing the key to be plugged into only one receptacle of the two or more receptacles of the 3D printer, the key comprising a conduit having an entrance and an exit, a coupling portion, and an engagement portion, wherein the entrance to the conduit is coupled to the outlet end of the first filament guide tube to thereby form a closed filament path from the first container to the 3D printer.

Abstract: An additive manufacturing system for printing three-dimensional (3D) parts includes a print foundation, a print head, a drive mechanism, and a supporting surface that creates an air bearing for parts under construction as they move through the system. The print head is configured to print a 3D part onto the print foundation in a layer-by-layer manner in a vertical print plane. The drive mechanism is configured to index the print foundation substantially along a horizontal print axis during printing of the 3D part. The support surface is provided by a table extending along the horizontal axis. The table has a plurality of air jets forming an air platen, which generates the air bearing for supporting the 3D part as it is incremented along the print axis.

Abstract: A filament feeding device includes a drive mechanism and a displacement sensor. The drive mechanism is configured to feed a filament along a feed path. The displacement sensor is positioned adjacent the feed path and is configured to determine a velocity and direction in which the filament is fed along the feed path based on at least two capacitance measurements that vary in response to movement of the filament along the feed path.

Abstract: A method for printing three-dimensional parts with an additive manufacturing system, comprising printing successive layers having increasing cross-sectional areas, and printing layers of a three-dimensional part onto the previously printed layers, where a last layer of the previously printed successive layers has a cross-sectional area that is at least as large as a footprint area of the three-dimensional part.

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.
