Abstract

Methods and systems are disclosed for three-dimensional printing directly onto an article of apparel. Disclosed is a method and system for direct three-dimensional printing onto an article of apparel, including positioning at least a portion of the article on a tray in a three-dimensional printing system, the portion being positioned substantially flat on the tray, printing a three-dimensional material directly onto the article using a three-dimensional pattern, curing the printed material, and removing the article from the three-dimensional printing system.

Claims

1. A method of direct three-dimensional printing onto an article of footwear, comprising:

positioning at least a portion of the article of footwear on a tray in a three-dimensional printing system, the at least a portion comprising a fabric and being positioned substantially flat on the tray to provide a fabric printing substrate;

printing a three-dimensional material directly onto the fabric of the at least a portion of the article of footwear using a three-dimensional pattern;

curing the three-dimensional material; and

removing the article of footwear from the three-dimensional printing system, wherein the fabric printing substrate is part of the article of footwear.

2. The method according to claim 1, wherein the at least a portion of the article of footwear comprises a side of an upper,

wherein the printing onto the fabric of the side of the upper comprises printing a plurality of loops onto the fabric of the side of the upper, and

wherein each loop of the plurality of loops extends upwardly from a lower portion of the side of the upper and around a lace aperture to provide the upper with structural support.

3. The method according to claim 1, wherein the printing onto the fabric of the at least a portion of the article of footwear further comprises allowing the three-dimensional material to at least partially absorb into the fabric prior to the curing.

4. The method according to claim 1, wherein the printing onto the fabric of the at least a portion of the article of footwear further comprises:

printing a first layer of the three-dimensional material;

allowing the first layer of three-dimensional material to at least partially absorb into the fabric of the at least a portion of the article of footwear;

curing the first layer of three-dimensional material;

printing at least one additional layer of the three-dimensional material on the cured first layer; and

curing the at least one additional layer.

5. The method according to claim 4, wherein the first layer has a first modulus of elasticity and the at least one additional layer has a second modulus of elasticity different than the first modulus.

6. The method according to claim 4, wherein the first layer has a first color and the at least one additional layer has a second color.

7. The method according to claim 1, wherein the fabric of the at least a portion of the article of footwear comprises at least one of a textile, a natural fabric, a synthetic fabric, a knit, a woven material, a nonwoven material, a mesh, a leather, a synthetic leather, a polymer, a rubber, and a foam.

8. The method according to claim 1, wherein the fabric of the at least a portion of the article of footwear has at least one irregular surface having an irregular surface topology.

9. The method according to claim 8, wherein the at least one irregular surface is the fabric printing substrate on which the printing occurs, and

wherein printing the three-dimensional material comprises compensating for irregularities in the at least one irregular surface by at least one of adjusting a distance between a printhead and the at least one irregular surface and adjusting at least one of size, rate, and distribution of material ejected from the printhead.

10. The method according to claim 1, wherein the removing the article of footwear does not require a release layer disposed between the three-dimensional material and the tray.

11. The method according to claim 1, wherein the three-dimensional material comprises at least one of an ink, a resin, an acrylic, a polymer, a thermoplastic material, a thermosetting material, and a light-curable material.

12. The method according to claim 1, wherein the three-dimensional material further comprises a filler material.

13. The method according to claim 1, wherein the three-dimensional material is adhered or bonded to the fabric of the at least a portion of the article of footwear.

14. A method of fabricating an article of footwear, comprising:

providing a three-dimensional pattern to a print server;

positioning at least a portion of the article of footwear on a tray in a three-dimensional printing system, the at least a portion comprising a fabric and being positioned substantially flat on the tray to provide a fabric printing substrate;

aligning the at least a portion of the article of footwear on the tray with the three-dimensional pattern;

printing a three-dimensional material directly onto the fabric of the at least a portion of the article of footwear using the three-dimensional pattern on the print server and the three-dimensional printing system;

curing the three-dimensional material;

removing the article of footwear from the three-dimensional printing system, wherein the fabric printing substrate is part of the article of footwear; and

assembling the article of footwear using the at least a portion of the article of footwear.

15. The method according to claim 14, wherein the at least a portion of the article of footwear comprises a side of an upper,

wherein the printing onto the fabric of the side of the upper comprises printing a plurality of loops onto the fabric of the side of the upper, and

wherein each loop of the plurality of loops extends upwardly from a lower portion of the side of the upper and around a lace aperture to provide the upper with structural support.

16. The method according to claim 14, wherein the printing onto the fabric of the at least a portion of the article of footwear further comprises:

printing a first layer of the three-dimensional material;

allowing the first layer of three-dimensional material to at least partially absorb into the fabric of the at least a portion of the article of footwear;

curing the first layer of three-dimensional material;

printing at least one additional layer of the three-dimensional material on the cured first layer; and
