The Progress and Application of Rapid Prototying Technology

The principle and application of rapid prototyping technology were presented. Several typical rapid prototyping technology were introduced, such as the Stereo Lithography Appearance, Laminated object manufacturing, fused deposition modeling, selective laser sintering, three dimensional spray adhesive technology. The rapid prototyping technology was used in manufacturing, clinical surgical, defense technology, ceramics, dental, and so on. The choke point of rapid prototyping technology application was analyzed, such as molding materials, precision error, and the performance of data sharing software. The future development trend of rapid prototyping technology is prospected also.
