Abstract
A solid freeform fabrication process and apparatus for making a three-dimensional object. The process comprises the steps of (1) operating a multiple-channel material deposition sub-system for dispensing droplets of selected liquid compositions and solid powders at predetermined proportions; (2) providing an object platform in close working vicinity to the deposition sub-system to receive the deposition materials therefrom; and (3) during the material deposition process, moving the deposition sub-system and the platform relative to each other in an X-Y plane defined by first and second directions and in a Z direction orthogonal to the X-Y plane so that the materials are deposited to form a first layer of the object. These steps are repeated to deposit multiple layers for forming a three-dimensional shape. These steps are preferably executed under the control of a computer system by taking additional steps of (4) creating an image of the object on the computer with the image including a plurality of segments defining the object and each segment being preferably coded with a color and/or a material composition; (5) generating programmed signals corresponding to each of the segments in a predetermined sequence; and (6) moving the deposition sub-system and the platform relative to each other in response to said programmed signals. Preferably, the system is also operated to generate a support structure for any unsupported feature of the object.

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.
