Abstract

A consumable material comprising an exterior surface having encoded markings that are configured to be read by at least one sensor of a direct digital manufacturing system, where the consumable material is configured to be consumed in the direct digital manufacturing system to build at least a portion of a three-dimensional model.

Claims

1. A marked consumable material for use in a direct digital manufacturing system, the marked consumable material comprising an exterior surface having encoded markings that are configured to be read by at least one sensor of the direct digital manufacturing system, wherein the marked consumable material is configured to be consumed in the direct digital manufacturing system to build at least a portion of a three-dimensional model.

2. The marked consumable material of claim 1, wherein the marked consumable material comprises a filament having a length, and wherein the encoded markings extend along at least a portion of the length of the filament.

3. The marked consumable material of claim 2, wherein the encoded markings comprise a plurality of paths, and wherein at least one of the plurality of paths extends along at least a portion of the length of the filament.

4. The marked consumable material of claim 2, wherein the filament comprises a substantially cylindrical geometry having an average diameter ranging from about 0.8 millimeters to about 2.5 millimeters.

5. The marked consumable material of claim 2, wherein the filament has a cross section with a width and thickness, wherein the width of the cross section ranges from about 1.0 millimeter to about 10.2 millimeters, and wherein the thickness of the cross section ranges from about 0.08 millimeters to about 1.5 millimeters.

6. The marked consumable material of claim 1, wherein the encoded markings comprise a plurality of trenches extending within an exterior surface of the consumable material.

7. The marked consumable material of claim 6, wherein the plurality of trenches have an average depth from the exterior surface ranging from about 1.3 micrometers to about 51 micrometers.

8. The marked consumable material of claim 1, wherein the encoded markings comprise one or more types of encoded information selected from the group consisting of local consumable material cross-sections, consumable material extrusion parameters, amount of the marked consumable material remaining, measurements of local consumable material fingerprint characteristics, material types, material compositions, material colors, manufacturing information for the marked consumable material, product codes, material origin information, software and firmware updates for the direct digital manufacturing system, media-based information, and combinations thereof.

9. A method of manufacturing a marked consumable material for use in a direct digital manufacturing system, the method comprising:

providing a consumable material precursor comprising an exterior surface, wherein the consumable material precursor is formed from an extrudable material; and

forming encoded markings at the exterior surface of the consumable material precursor, wherein the encoded markings are configured to be read by at least one sensor in the direct digital manufacturing system, and wherein the marked consumable material is configured to be consumed in the direct digital manufacturing system to build at least a portion of a three-dimensional model.

10. The method of claim 9, wherein providing the consumable material precursor comprises forming the consumable material precursor from the extrudable material.

11. The method of claim 9, wherein the consumable material precursor comprises a filament precursor having a length, and wherein forming the encoded markings comprises forming the encoded markings at the exterior surface along at least a portion of the length of the filament precursor.

12. The method of claim 9, wherein forming the encoded markings at the exterior surface comprises forming the encoded markings as a plurality of trenches within the exterior surface.

13. The method of claim 12, wherein forming the encoded markings as the plurality of trenches within the exterior surface comprises a laser ablation process.

14. The method of claim 9, and further comprising reading the formed encoded markings prior to loading the marked consumable material to a supply source.

15. The method of claim 9, wherein forming the encoded markings at the exterior surface comprises performing at least one marking technique selected from the group consisting of laser ablation processes, coating processes, mechanical impression processes, surface property modification processes, and combinations thereof.

16. A method for building a three-dimensional model with a direct digital manufacturing system, the method comprising:

feeding a marked consumable material to the direct digital manufacturing system, the marked consumable material comprising an exterior surface having encoded markings;

reading at least a portion of the encoded markings while feeding the marked consumable material to the direct digital manufacturing system;

melting the marked consumable material to at least an extrudable state in the direct digital manufacturing system; and

depositing the melted material from a deposition head of the direct digital manufacturing system to form the three-dimensional model in a layer-by-layer manner.

17. The method of claim 16, wherein reading the portion of the encoded markings comprises optically detecting the encoded markings with an optical sensor assembly.

18. The method of claim 16, and further comprising transmitting signals relating to the read encoded markings to a controller of the direct digital manufacturing system.

19. The method of claim 16, and further comprising adjusting at least one property of the direct digital manufacturing system based on the read encoded markings.

20. The method of claim 16, wherein reading the portion of the encoded markings is performed at one or more locations between and including a supply source of the marked consumable material and the deposition head of the direct digital manufacturing system.
