A method and process for computer-controlled manufacture of three-dimensional objects involves dispensing a layer of liquid, insoluble material (25) onto a platform (15) at predetermined locations, which them hardens. A second media (35), preferably water soluble, is then sprayed onto this layer to thereby encapsulate the hardened insoluble media. The uppermost surface of this encapsulant is planed, thus removing a portion of the encapsulant to expose the underlying insoluble material for new pattern deposition. After the resulting planing residue is removed, another layer of liquid, insoluble media is dispensed onto the planed surface. The insoluble media can be of any color and may vary from layer to layer, and from location within a layer to location within a layer. These steps are repeated. until the desired three-dimensional object (55), surrounded by a mold, is completed. At this point, the abject is either heated or immersed in a solvent, thereby dissolving the mold and leaving the three-dimensional object intact.
