Abstract
Three-dimensional printing kits can include a powder bed material and a fusing agent to selectively apply to the powder bed material. The powder bed material can include polymer build particles and cellulose particles. The cellulose particles can be chemically and thermally stable at a melting point temperature of the polymer build particles. The fusing agent can include water and a radiation absorber to absorb radiation energy and convert the radiation energy to heat.
