Abstract: An example of a dispersion includes cesium tungsten oxide nanoparticles, a zwitterionic stabilizer, and a balance of water. An example of a jettable composition includes cesium tungsten oxide nanoparticles, a zwitterionic stabilizer, a surfactant, a co-solvent, and a balance of water. A method for improving the stabilization of a jettable composition includes incorporating a zwitterionic stabilizer in the jettable composition, which includes the cesium tungsten oxide nanoparticles, the surfactant, the co-solvent, and the balance of water.

Abstract: The present disclosure is drawn to material sets and 3-dimensional printing systems that include a fusing agent. One example of a material set can include a fusing agent and a detailing agent. The fusing agent can include water, a carbon black pigment, and a water-soluble co-solvent in an amount from 20 wt % to 60 wt %. The detailing agent can include water and a black dye. In another example, a material set can include a fusing agent and a thermoplastic polymer powder.
