RP technology of complex three dimensional machining of an entity into a series of discrete sheet processing, greatly reduces the difficulty of processing, has the following characteristics:
⑴ molding process of rapid, modern competitive product market;
B solid of arbitrary complex shapes can be made;
C direct drive with the CAD model, design and manufacture of highly integrated, its intuitive nature and ease of modification to the perfect product design to provide an excellent design environment;
⑷ molding without special jigs, tooling, cutting tools, saving costs, and shorten the production cycle.
⑸ the high integration of the technology is not only the inevitable outcome of the development of modern science and technology, as well as their application, with the distinctive characteristics of the high-tech.
