ABSTRACT:
A rapid prototyping system makes three-dimensional objects by sequentially depositing multiple layers of solidifying material on a flexible sheet substrate. The substrate is held against the top surface of a vacuum platen during deposition of the layers. When the object is completed, the substrate is released from the vacuum platen. By flexing the substrate, the object is peeled away from the substrate.
