Appl. No.:

17/788350

Inventors:

- Spring TX, US
Graciela Emma Negri Jimenez - San Diego CA, US
Shannon Reuben Woodruff - San Diego CA, US
Jason Christopher Butler - San Diego CA, US

Assignee:

Hewlett-Packard Development Company, L.P. - Spring TX

International Classification:

B29C 64/165

Abstract:

The present disclosure describes multi-fluid kits for three-dimensional printing, three-dimensional printing kits, and methods of making three-dimensional printed objects. In one example, a multi-fluid kit for three-dimensional printing can include a fusing agent and an antioxidant agent. The fusing agent can include water and an electromagnetic radiation absorber. The electromagnetic radiation absorber can absorb radiation energy and convert the radiation energy to heat. The antioxidant agent can include water and a dispersion of a secondary antioxidant.

Abstract:

Disclosed herein are methods for three-dimensional printing. In an example, disclosed herein is a method for three-dimensional printing comprising: (A) depositing a layer of build material; and then carrying out at least one of the following: (B) selectively applying: a cyan ink composition, a yellow ink composition, a magenta ink composition, and/or a black ink composition on the build material; (C) selectively applying a first fusing agent on the build material, wherein the first fusing agent comprises at least one nanoparticle, wherein the nanoparticle comprises at least one metal oxide shown in formula (1): MM′O(1); (D) selectively applying a second fusing agent on the build material, wherein the second fusing agent comprises at least one near infrared absorbing compound; (E) repeating (A) and at least one of (B), (C), and (D) at least once to form a three-dimensional part.
