Abstract�� Rapid prototyping technology makes the manufacturing of functionally gradient materials objects come true for its digital concurrent design and manufacturing. The design of supporter generation defines the machining accuracy of functionally gradient material(FGM)parts in the process of rapid prototyping. An algorithm based on sorting by adjacency in layers was adopted a new method of supporter generation which is based on polygon boolean operation in order to solve the problem occurred in digital manufacturing of FGM parts were proposed. The support spaces between layers can adaptively change according to the geometry and material information of FGM objects, which makes the machining accuracy of rapid prototyping increase. Finally, an example of adaptive support is presented to validate the algorithm.
