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 a tinted anti-coalescing agent. The fusing agent can include water and an electromagnetic radiation absorber that absorbs radiation energy and converts the radiation energy to heat. The tinted anti-coalescing agent can include an aqueous liquid vehicle, a colored dye dissolved in the aqueous liquid vehicle, and an organosilane. The organosilane can have a central silicon atom covalently coupled to multiple hydrolysable groups and to an organic group by covalent bonding to a carbon atom in the organic group, wherein the organic group is not susceptible to hydrolysis.
