Abstract

Apparatuses and methods for depositing a substance onto an article are disclosed, including apparatuses and methods of directly printing on three-dimensional articles, as well as the articles printed thereby or having a substance deposited thereon. In some cases, the apparatuses and methods involve creating a re-circulating relative motion between at least one article and a substance deposition device. In some embodiments, the articles can be conveyed in a closed loop path past one or more substance deposition devices. The articles can be conveyed past the substance deposition device(s) one or more times, and during each pass by the substance deposition device(s), a portion of a predetermined pattern may be applied to the articles by the substance deposition device(s).

providing the at least one article comprises providing a group of articles;

said conveyor comprises a carrier having article holders joined thereto in an at least partially radial array; and

at least a portion of the relative motion is circular.

14. The process of claim 1, wherein:

providing the at least one article comprises providing a group of articles;

said conveyor comprises a track in the configuration of a loop, having article holders joined to the track; and

the relative motion is provided by moving the article holders around the loop.

15. The process of claim 9, wherein the articles in the batch move in substantially planar motion.

16. The process of claim 15, wherein the articles move in a substantially horizontal plane.

17. The process of claim 15, wherein the articles move in a substantially vertical plane.

18. The process of claim 1, wherein the relative motion is created, at least in part, by moving the article with respect to the deposition device.

19. The process of claim 1, wherein during the relative motion, the deposition device remains substantially stationary.

20. The process of claim 1, wherein each time the article passes by the deposition device, a portion of the predetermined pattern of the substance is deposited onto at least a portion of the surface of the article.

21. The process of claim 1, wherein substance is a material that is curable with ultra-violet light.

22. The process of claim 1, wherein the substance is an acrylate-based ink.

23. The process of claim 1, wherein:

the step of providing a substance deposition device comprises providing a plurality of non-contacting, depositing-on-demand, substance deposition devices;

the step of providing at least one three dimensional article comprises providing a batch of three dimensional articles;

the step of creating a re-circulating relative motion between the articles and the substance deposition devices comprises passing the batch of articles by the substance deposition devices at least two times in the same direction; and

the step of depositing the substance comprises, during the relative motion, for each of the articles in the batch, depositing material onto at least a portion of the surface of the articles by using the devices, wherein in each pass, the deposition devices deposit only a portion of the total predetermined pattern to be formed, and the articles are passed by the devices at least twice to form the predetermined pattern.

24. The process of claim 23, wherein at least some of the substance deposition devices comprise inkjet print heads.

25. The process of claim 24, wherein:

at least some of the inkjet print heads are color inkjet print heads that are configured to print color; and

the step of depositing the substance comprises depositing portions of the pattern of the substance, at least some of which portions are printed color portions, by using the color inkjet print heads, wherein the multiple portions form the predetermined pattern.

26. The process of claim 24, wherein:

at least one of the inkjet print heads is configured to print a white base coat; and

the step of depositing the substance comprises depositing a portion of the predetermined pattern of the material, at least one of which portions is a white base coat, by using the inkjet print head configured to print a white base coat.
