Build materials for 3D printing applications are described herein which, in some embodiments, comprise a dye component operable to alter spectral characteristics of the printed part over the course of the build cycle. In some embodiments, for example, the dye component can provide desirable light penetration depth during article printing and sufficient optical clarity during final light curing processes.

A multi-fluid kit for three-dimensional printing can include a fusing agent and a detailing agent. The fusing agent can include water and a radiation absorber. The radiation absorber absorbs radiation energy and converts the radiation energy to heat. The detailing agent includes a lipophilic phase discontinuously dispersed within an aqueous phase by a surfactant. The lipophilic phase includes an organosilane having a central silicon atom coupled to a C6 to C24 aliphatic or alicyclic hydrocarbon and multiple hydrolyzable groups. The organosilane is present in the detailing agent at from about 1 wt % to about 20 wt %.
