80年代后期发展起来的快速原型(Rapid Prototyping简称RP)技术,被认为是近20年制造技术领域的一次重大突破,其对制造行业的影响可与数控技术的出现相比。RP系统综合机械工程、CAD、数控技术、激光技术及材料科学技术,可以自动、直接、快速、精确地将设计思想物化为具有一定功能的原型或直接制造零件或模具,有效地缩短产品的研究 The Rapid Prototyping (RP) technique developed in the late 1980s is considered as a major breakthrough in the field of manufacturing technology in the past 20 years. Its impact on the manufacturing industry can be compared with the emergence of numerical control technology. RP system integrates mechanical engineering, CAD, numerical control technology, laser technology and material science technology to automatically, directly, quickly and accurately materialize design ideas into prototypes with certain functions or to directly manufacture parts or molds to effectively shorten product research
