In an example of a method for three-dimensional (3D) printing, a polymeric build material is applied to form a build material layer. A fusing agent is selectively applied, based on a 3D object model, onto the build material layer to form a patterned portion. A hydrophobic agent is selectively applied, based on the 3D object model, onto at least a portion of the patterned portion. The hydrophobic agent includes a lipophilic phase discontinuously dispersed within an aqueous phase by a surfactant, wherein the lipophilic phase includes an organosilane having a central silicon atom coupled to a C6 to C24 aliphatic or alicyclic hydro-carbon and multiple hydrolyzable groups, wherein the organosilane is present in the hydrophobic agent at from about 1 wt % to about 20 wt %. The build material layer is exposed to energy to selectively coalesce the patterned portion and form a 3D object layer having a hydrophobic portion.

This disclosure describes three-dimensional printing kits, methods, and systems for three-dimensional printing with directionally-dependent reflective particles. In one example, a three-dimensional printing kit 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 particles and directionally-dependent reflective particles. The directionally-dependent reflective particles can be chemically and thermally stable at a melting point temperature of the polymer particles. The fusing agent can include water and a radiation absorber to absorb radiation energy and convert the radiation energy to heat.
