  • Patent number: 7255551
    Abstract: A system is provided for high volume print-forming of structures made up of multiple separate layers. A support bed is provided which has multiple steps arrayed thereon at different heights. Substrate blocks rest upon each of the steps. A printing process is utilized to print material from which the structures are to be formed down onto the substrate blocks. This printing process prints different layers onto each of the substrate blocks. The substrate blocks then move to a different step on the support bed and the printing process is repeated. Each support block has a partial structure thereon which receives its next successive layer in each printing cycle until the partial structure becomes a completed structure by having each of its layers sequentially printed thereon. Subsystems are provided for moving the substrate blocks upon the support bed and for properly holding and aligning substrate blocks upon the support bed.
    Type: Grant

    Assignee: Eoplex Technologies, Inc.
    Inventors: Charles S. Taylor, Paul Cherkas, Robert A. Geshlider, Dwight P. Morejohn, Sue W. Vican, Bhupendra O. Shah, Eric Reeser

  • Patent number: 5348693
    Abstract: A method and system for making a three dimensional product wherein the size and shape of a plurality of cross-sectional segments of the three dimensional object are determined which when assembled together in a particular sequence form the desired three dimensional shape. Thin layers of material in the shape of each of the cross-sectional segments are applied in the particular sequence in which they form the three dimensional object. The application of each of the layers is much like a lithographic printing process in that a resin may be applied by a roller in the shape of the cross-sectional segments.
