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 that absorbs radiation energy and converts the radiation energy to heat. The antioxidant agent can include a liquid vehicle with water and from about 0.5 wt % to about 15 wt % hindered phenolic antioxidant dispersed in the liquid vehicle.
