Adaptive Slicing with Sloping Layer Surfaces in Rapid Prototyping 2001-28-0072

The competition on an internationalized automobiles market forces companies to bring out better products at an increased pace. To be able to follow this trend, significant advances in the technology of rapid prototyping, have produced new capability to develop the automotive parts of any degree of intricacy with high geometric accuracy, in least possible build time.
Adaptive slicing technique along with sloping layer surfaces, serves for the above said purpose. This technique produce surfaces that closely match the shape of the required surface. This greatly reduces the stair case effect which is characteristic of layered components with square edges. Two measures of error are considered and a method of predicting these measures for sloping layer surfaces is outlined. To cater for different manufacturing requirements, a method to produce parts with either an inside or outside tolerance, or a combination of both, is presented. Finally, some problems associated with surfaces joins, vertices, and inflection points are considered and some solutions proposed.
