Abstract
A multi-fluid kit for three-dimensional printing can include a wetting agent and a binding agent. The wetting agent can include from 0 wt % to about 49.8 wt % water, from about 0.5 wt % to about 30 wt % film-forming organic solvent that can have a boiling point from greater than about 100° C. to about 350° C., and from about 30 wt % to about 99.5 wt % amphiphilic solvent that can have a boiling point from about 45° C. to less than about 100° C. The amphiphilic solvent can be water-miscible and can be present in the wetting agent at a greater concentration than the water and at a greater concentration than the film-forming solvent. The binding agent can include from about 2 wt % to about 30 wt % of a polymer binder dispersed in an aqueous liquid vehicle.
