Abstract
The present disclosure describes multi-fluid kits for three-dimensional printing, three-dimensional printing kits, and methods of making three-dimensional printed articles. In one example, a multi-fluid kit for three-dimensional printing can include a fusing agent and a second fluid agent. The fusing agent can include water and a radiation absorber. The radiation absorber can absorb radiation energy and convert the radiation energy to heat. The fusing agent or the second fluid agent can include a water-soluble or water-dispersible dihydrazide antioxidant.
Claims24
(canceled)
The three-dimensional printing kit of claim 8, wherein the agent is an antioxidant agent, and the three-dimensional printing kit further comprises a detailing agent comprising a detailing compound, wherein the detailing compound reduces a temperature of powder bed material onto which the detailing agent is applied.
(canceled)
The three-dimensional printing kit of claim 8, wherein the water-soluble or water-dispersible dihydrazide antioxidant is present in the agent in an amount ranging from about 0.1 wt % to about 10 wt % with respect to a total weight of the agent.
(canceled)
The three-dimensional printing kit of claim 10, wherein the radiation absorber is selected from the group consisting of a metal dithiolene complex, carbon black, a near-infrared absorbing dye, a near-infrared absorbing pigment, metal nanoparticles, a conjugated polymer, and a combination thereof.
The three-dimensional printing kit of claim 10, wherein the fusing agent is colorless.
A three-dimensional printing kit, comprising:
- a powder bed material comprising polymer particles;
- and
- an agent comprising water and a water-soluble or water-dispersible dihydrazide antioxidant to be selectively applied to the powder bed material.
-15. (canceled)
An agent, comprising:
- from about 0.1 wt % to about 10 wt %, with respect to a total weight of the agent, of a water-soluble or water-dispersible dihydrazide antioxidant;
- from about 1 wt % to about 50 wt % of an organic co-solvent;
- and
- a balance of water.
