Abstract
This disclosure describes hydrogel three-dimensional printing kits, methods of three-dimensional printing hydrogels, and hydrogel three-dimensional printing systems. In one example, a hydrogel three-dimensional printing kit can include a particulate build material, a crosslinking agent, a whitening agent, and a coloring agent. The particulate build material can include a polyhydroxylated swellable polymer. The crosslinking agent can include water and a crosslinker that is reactive with hydroxyl groups of the polyhydroxylated swellable polymer to crosslink the polyhydroxylated swellable polymer. The whitening agent can include water and a dispersed white pigment. The coloring agent can include water and a colorant.
