Abstract: A multi-fluid kit for three-dimensional printing can include a wetting agent and a binding agent. The wetting agent can include from about 5 wt % to about 80 wt % water-miscible hydroxyl-containing solvent and from about 20 wt % to about 95 wt % water. The water-miscible hydroxyl-containing solvent can be selected from methyl lactate, ethyl lactate, propyl lactate, 2-methyl 2,4-pentandiol, 1,2 hexanediol, 1,2 pentanediol, or a mixture thereof. The binding agent can include from about 2 wt % to about 30 wt % polymer binder dispersed in an aqueous liquid vehicle.
