1. A method for building a three-dimensional object with an extrusion-based layered deposition system having a mount, the method comprising: providing a first consumable assembly to the extrusion-based layered deposition system, wherein the first consumable assembly comprises a container portion retaining a supply of a filament, a first extruder portion, and a flexible guide tube configured to guide the filament from the container portion to the extruder portion;placing the container portion at a location that is offset from the mount;inserting the first extruder portion of the consumable assembly in the mount of the extrusion-based layered deposition system such that the guide tube extends between the location of the placed container portion and the inserted extruder portion;building at least a portion of the three-dimensional object from the filament retained in the container portion; andinterchanging the first consumable assembly with the first extruder portion with a second consumable assembly with a second extruder portion. 2. The method of claim 1, wherein the building step comprises: feeding successive portions of the filament from the container portion, through the guide tube, and to the first extruder portion;melting the successively fed portions of the filament in the first extruder portion to form an extrudable material; andextruding the extrudable material from the first extruder portion. 3. The method of claim 1, and further comprising creating an electrical connection between the inserted first extruder portion and the extrusion-based layered deposition system. 4. The method of claim 1, wherein the second consumable assembly comprises a second container portion, a second guide tube, and the second extruder portion, and wherein interchanging the first consumable assembly with the second consumable assembly comprises: removing the first extruder portion and the guide tube of the first consumable assembly from the extrusion-based layered deposition system;placing the second container portion at a location that is offset from the mount; andinserting the second extruder portion in the mount such that the second guide tube extends between the location of the placed second container portion and the inserted second extruder portion. 5. The method of claim 1, wherein placing the container portion at the location that is offset from the mount comprises loading the container portion to a bay of the extrusion-based layered deposition system. 6. The method of claim 1, wherein the container portion comprises an outer casing and a spool assembly disposed within the outer casing, and wherein the building step comprises drawing successive segments of the filament from the spool and into the guide tube. 7. The method of claim 1, wherein the container portion comprises an outer casing, wherein the supply of the filament comprises a coil of the filament, and wherein the building step comprises drawing successive segments of the filament from the coil and into the guide tube. 8. A method for building a three-dimensional object with an extrusion-based layered deposition system having a mount, the method comprising: providing a consumable assembly to the extrusion-based layered deposition system, wherein the consumable assembly comprises a container portion; an extruder portion; and a filament extending within and between the container portion and the extruder portion;placing the container portion at a location that is offset from the mount;inserting the extruder portion derived from the consumable assembly in the mount of the extrusion-based layered deposition system;building at least a portion of the three-dimensional object by drawing successive portions of the filament from the placed container portion to the inserted extruder portion;removing the consumable assembly with the extruder portion, the container portion, and any remaining portions of the filament that are within the extruder portion, within the container portion, and extending between the extruder portion and the container portion, from use with the extrusion-based layered deposition system. 9. The method of claim 8, wherein and further comprising creating an electrical connection between the extruder portion and the extrusion-based layered deposition system. 10. The method of claim 8, wherein the building step comprises depositing an extrudable material of the filament from the inserted extruder portion onto a substrate assembly of the extrusion-based layered deposition system, and wherein the location that the container is placed at is offset from the substrate assembly. 11. The method of claim 10, wherein at least a portion of the substrate assembly is retained in a build chamber of the extrusion-based layered deposition system, wherein the location that the container is placed at is offset from the build chamber, and wherein the method further comprises heating the build chamber. 12. The method of claim 8, wherein the extruder portion comprises a liquefier tube and an extrusion tip connected to the liquefier tube, and wherein the building step comprises: feeding successive segments of the filament into the liquefier tube;melting the fed successive segments of the filament in the liquefier tube to form the extrudable material; andextruding the extrudable material from the extrusion tip. 13. The method of claim 12, wherein the extruder portion further comprises a drive mechanism, and wherein feeding successive segments of the filament into the liquefier tube comprises: engaging the successive segments of the filament with the drive mechanism; anddriving the engaged successive segments into the liquefier tube. 14. A method for building a three-dimensional object with an extrusion-based layered deposition system having a mount, the method comprising: providing an interchangeable consumable assembly to the extrusion-based layered deposition system, wherein the interchangeable consumable assembly comprises a container portion, an extruder portion comprising a liquefier tube and an extrusion tip, and a flexible guide tube interconnecting the container portion and the extruder portion to support a filament between the container portion and the extruder portion;placing the container portion at a location that is within or adjacent to the extrusion-based layered deposition system such that the container portion is not retained by the mount;inserting the extruder portion of the consumable assembly in the mount of the extrusion-based layered deposition system;moving successive segments of the filament from the container portion, through the guide tube, and into the liquefier tube of the inserted extruder portion;melting the successive segments of the filament in the liquefier tube of the inserted extruder portion to form an extrudable material;extruding the extrudable material from the extrusion tip of the inserted extruder portion; andmoving the mount with the inserted extruder portion while extruding the extrudable material from the extrusion tip to build at least a portion of the three-dimensional object from the extruded material. 15. The method of claim 14, wherein the extruder portion further comprises a heater, and wherein melting the successive segments of the filament in the liquefier tube comprises: providing electrical power from the extrusion-based layered deposition system to the heater of the inserted extruder portion to generate heat; andtransferring the heat from the heater to the liquefier tube of the inserted extruder portion. 16. The method of claim 14, and further comprising: removing the extruder portion and the guide tube from the extrusion-based layered deposition system; andinserting a second extruder portion of a second interchangeable consumable assembly to the mount. 17. The method of claim 16, and further comprising removing the container portion from the extrusion-based layered deposition system with the extruder portion and the guide tube. 18. The method of claim 14, wherein the extruder portion further comprises a drive mechanism, and wherein moving the successive segments of the filament comprises: engaging the successive segments of the filament with the drive mechanism; anddriving the engaged successive segments into the liquefier tube. 19. The method of claim 18, wherein the extruder portion further comprises a motor engaged with the drive mechanism, and wherein driving the engaged successive segments into the liquefier tube comprises operating the motor with electrical power from the extrusion-based layered deposition system. 20. The method of claim 14, wherein moving successive segments of the filament from the container portion comprise drawing the successive segments of the filament from a spool of the container portion.
