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 relates to light guide plates and methods for three-dimensional printing of light guide plates. In some examples, the method for 3D printing a light guide plate comprises: forming a plate body by depositing a layer of transparent build material on a build platform; based on a 3D object model of the plate body, inkjet printing fusing agent onto at least a portion of the layer of the transparent build material; and irradiating the fusing agent to heat the transparent build material and at least partially bind the portion of the transparent build material. In some examples, light scattering features are formed on the plate body by depositing a layer of transparent build material on the plate body; based on a 3D object model of light scattering features, inkjet printing fusing agent and scattering particles onto selected portions of the layer of transparent build material; and irradiating the fusing agent to heat the transparent build material and at least partially bind the portion of the transparent build material.
