The present disclosure describes multi-fluid kits for three-dimensional printing, materials kits for three-dimensional printing, 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 pore-promoting 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 pore-promoting agent can include water and a water-soluble pore-promoting compound. The pore-promoting compound can chemically react at an elevated temperature to generate a gas. |
