  • Three dimensional object fabrication techniques
    Patent number: 6627835
    Abstract: Method and apparatus for making an object. The invention includes the division of a shape of an object into a plurality of layers, and arranging the thickness of the layers based on the curvature of the object to be made. Further, curving edges of the object are replaced with linear sloping edges on the layers. The invention reduces the cost and improves the speed of rapid prototyping, especially with machining methods such as wire electrodischarge machining and laser machining.
