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.

Abstract: A printing method includes selecting an inkjet ink including a pigment, and selecting an active agent, including an electromagnetic radiation-absorbing active material, and an aqueous or non-aqueous vehicle. The method further includes inkjet printing the inkjet ink and the active agent directly onto a textile fabric. The textile fabric having the ink and active agent thereon is exposed to electromagnetic radiation.

Abstract: An example of a three-dimensional (3D) printing kit includes a build material composition and a fusing agent to be applied to at least a portion of the build material composition during 3D printing. The build material composition includes a thermoplastic elastomer having a melt enthalpy ranging from greater than 5 J/g to about 177 J/g. The fusing agent includes an energy absorber to absorb electromagnetic radiation to coalesce the thermoplastic elastomer in the at least the portion. The fusing agent is a core fusing agent and the energy absorber has absorption at least at wavelengths ranging from 400 nm to 780 nm; or the fusing agent is a primer fusing agent and the energy absorber is a plasmonic resonance absorber having absorption at wavelengths ranging from 800 nm to 4000 nm and having transparency at wavelengths ranging from 400 nm to 780 nm.
