  • Rapid prototyping method
    Patent number: 6231802
    Abstract: A volume sequential technique allows the production of prototypes from a liquid photopolymer precursor without requiring the CAD model to be decomposed into slices. Inverse Tomographic Construction (ITC) selectively cures the photopolymer in a vat without requiring it translating build platform.
    Type: Grant

  • Rapid prototyping method
    Patent number: 5663883
    Abstract: A rapid prototype modeling system operates to first electronically decompose a discrete part represented by an STL file into thick layers, which are then electronically sliced into cross sectional slices the thickness of a sheet of construction material. The slices are cut from sheets of the construction material in a pattern which permits construction of the layers by stacking the sheets. The layers are then stacked appropriately to create a physical model of the discrete part.
