  • Patent number: 6401002
    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.

  • Patent number: 6165406
    Abstract: A freeform fabrication process and apparatus for making a colorful 3-D object. The process includes (1) operating a multiple-channel droplet deposition device for supplying and, on demand, ejecting droplets of multiple liquid compositions containing a solidifiable baseline body-building material and different colorants; (2) providing a support platform a distance from this deposition device to receive the droplets therefrom; and (3) during the droplet ejecting process, moving the deposition device and the platform relative to one another in an X-Y plane and in a Z direction orthogonal to the X-Y plane so that the droplets are deposited to form multiple layers to build a colorful 3-D object.
