Rapid prototyping (RP) is a synthesize subject consisted of CAD technology, CNC technology, Laser technology and Materials technology. RP technology with a simple production process without molds can produce samples of all shapes, reducing development cycle and product design cost, quickening the schedule of new product design. These advantages bring fundamental changes for manufacturing industry. In this article, the development of rapid prototyping technology at home and abroad is introduced. The principle and manufacturing techniques of rapid prototyping as well as the four rapid prototyping methods currently used such as Stereo Lithography Apparatus, Selective Laser Sintering, Laminated Object Manufacturing, and Fused Deposition Modeling are analyzed. The materials used by RP are introduced. The future goals of RP technology is high precision, low cost, standardization and production of semi functional and functional products. RP will become one of the main forming processes of ceramic materials in 21st century.
