Abstract
A method and process for computer-controlled manufacture of three-dimensional objects involves dispensing a layer of a first material, such as a liquid, insoluble material onto a platform at predetermined locations corresponding to a cross-section of the object, which then hardens. A second medium, preferably water soluble, is then sprayed onto this layer to thereby encapsulate the hardened insoluble media. The uppermost surface of this encapsulant is planned, 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 planned surface. The insoluble media can be of any color and may vary from layer to layer, and from location within a layer to location with a layer. These steps are repeated, until the desired three-dimensional object, surrounded by a mold, is completed. At this point, the object is either heated or immersed in solvent, thereby dissolving the mold and leaving the three-dimensional object intact. Other system methods, and processes are also disclosed.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
