The mold is one of foundation industries, in the globalization market economy and under each kind of high technology and new technology swift and violent development situation, the fast economical mold has entrusted with the new mission and the brand-new connotation, the classification increases unceasingly, the fast economical pattern making material turns towards the multi- varieties seriation to make great strides forward, the craft has the new innovation and the breakthrough unceasingly, is published one after another with it supplementary equipment, the service domain in opens up unceasingly, the creation economic efficiency is more and more remarkable. Along with the commodity economy development, the intense market competition, the product renewal acceleration, is reducing the cycle to the fast economical pattern making technology, reduces the cost, will increase the precision and lengthens the life aspect the request to be able to be more and more high inevitably. Because it can cause the enterprise to win the market, creates the remarkable economic efficiency, more and more receives entrepreneur's favor and the concerned leader department's enormous attention and the policy fund support. Each kind of fast economical pattern making technology also can consummate mature and the development unceasingly in the promoted application process, as a result of the high technology and new technology development, each kind of technical bonding with the seepage, for the adaption production in different demand, surely will be able to form some, the frugal energy, the frugal material fast pattern making technology new from now on.

前言：
随着全球经济的发展，新的技术革命不断取得新的进展和突破，技术的飞跃 发展已经成为推动世界经济增长的重要因素。市场经济的不断发展，促使工业产品越来越向多品种、小批量、高质量、低成本的方向发展，为了保持和加强产品在市场上的竞争力，产品的开发周期、生产周期越来越短，于是对制造各种产品的关键工艺装备——模具的要求越来越苛刻。 一方面企业为追求规模效益，使得模具向着高速、精密、长寿命方向发展；另一方面企业为了满足多品种、小批量、产品更新换代快、赢得市场的需要，要求模具向着制造周期短、成本低的快速经济的方向发展。计算机、激光、电子、新材料、新技术的发展，使得快速经济制模技术如虎添翼，应用范围不断扩大，类型不断增多，创造的经济效益和社会效益越来越显著。 快速经济制模技术与传统的机械加工相比，具有制模周期短、成本低、精度与寿命又能满足生产上的使用要求，是综合经济效益比较显著的一类制造模具的技术，概括起来，有以下几种类别。
1快速原型制造技术 快速原型制造技术简称RPM，是80年代后期发展起来的一种新型制造技术。美国、日本、英国、以色列、德国、中国都推出了自己的商业化产品，并逐渐形成了新型产业。 RPM是电脑、激光、光学扫描、先进的新型材料、计算机辅助设计(CAD)、计算机辅助加工(CAM)、数控(CNC)综合应用的高新技术。在成型概念上以平面离散、堆积为指导，在控制上以计算机和数控为基础，以最大柔性为总体目标。它摒弃了传统的机械加工方法，对制造业的变革是一个重大的突破，利用RPM技术可以直接或间接地快速制模，该技术已被汽车、航空、家电、船舶、医疗、模具等行业广泛应用。。
