A method for the rapid preparation of patterns, molds, dies or forms, consists of a CAD/CAM system (including a postprocessor) in which is modeled the three-dimensional object for which the imprint is to be prepared, a robot with controller and tool bit or end effector, and one or more matrices each containing an array of slidable pins or rods. By displacing the pin/rod elements along their axis by determined amounts according to the shape of the object for which the imprint is being prepared, a pattern or mold or die or form is obtained for producing the three-dimensional object. |
