Title:: The Development of Rapid Prototyping Technology and Its Application in Ceramic Product Fabrication

摘要:: 集成了CAD技术、数控技术、激光技术和材料技术等现代科技成果的快速成型技术，可以在不用模具和工具的条件下生成几乎任意复杂形状的零部件，有效地缩短了产品的研发周期，提高了产品设计、制造的一次成品率，降低了产品开发成本，给制造业带来了根本性的变化。介绍了国内外快速成型技术的发展状况，分析了快速成型技术的原理和特点，介绍了目前应用较多的立体光固化、选择性激光烧结、分层实体制造、熔积成型等快速成型方法以及快速成型使用的材料。快速成型技术正朝着精密化、低成本、标准化方向发展，并以能直接生产半功能性、功能性零件为目标。快速成型技术必将成为21世纪陶瓷材料的主要成型工艺之一。

Abstract:: 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.
