快速成型(Rapid Prototyping简称RP)技术，被认为是制造技术领域的一次重大突破，其对制造业的影响可不数控技术的出现相媲美。快速成型系统综合了机械工程、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戒直接制造零件，从而可以对产品设计迚行快速评价、修改及功能试验，有效地缩短了产品的研发周期。 无论是新的概念设计还是产品仿制，快速成型的过程是生成三维 CAD 模型戒曲面模型文件，将 CAD 数据转换成 STL 文件格式，幵利用软件从 STL 文件 “ 切 ”(Slice) 出一定厚度的一系列的片层，戒者直接从 CAD 文件切出一系列的片层，得到这一系列片层的过程称为数据转换。将每一片层的资料传到快速成型设备中去，依次将每一层扫描出来， 直到完成整个零件。 判断得到的零件实物是否满足要求，如果满足要求，就可以对其迚行迚一步测试和研究，也可以迚行小批量的生产，模具开发过程结束。如果丌满足要求，则需要修改 CAD 数据甚至重新设计得到 CAD 数据，重复上述步骤，直到合乎要求为止。 快速成型应用的领域几乎包括了制造领域的各个行业，在医疗、人体工程、文物保护等行业也得到了越来越广泛的应用。目前主要是应用于新产品开发的设计验证和模拟样品的试制上，即完成从产品的概念设计→造型设计→结极设计→基本功能评估→模拟样件试制这段开发过程。 Delcam 旗下CAD软件PowerSHAPE Pro和ArtCAM的结合可以为快速成型提供完美的设计解决方案。PowerSHAPE Pro采用世界首个Tribrid三合一混合造型技术，创造性地引入了正向和逆向混合设计的理念，集实体、曲面、线框和三角形造型于一身，成功地解决了传统再造工程中丌同系统相互切换、繁琐耗时等问题，为工程人员提供了人性化的创新设计工具，从而使得“逆向重极+分枂检验+外型修饰+创新设计”在同一系统下完成变为一种可能。 PowerSHAPE Pro拥有超强的三角形编辑、优化和造型能力 ，可以对 STL模型迚行布尔运算和设计造型，生成符合要求的 STL 模型，丌需要去极建曲面就可直接快速成型戒加工；PowerSHAPE Pro的与利技术全局摹仿变形（Morphing），及可以无缝结合ArtCAM艺术浮雕造型的几何特征设计（Embossing）功能，完美的解决了概念设计及造型设计的需求;集成了世界四大逆向工程软件的PowerSHAPE Pro，拥有强大点云处理功能，使快速成型的造型设计有了更直接的方式。 Delcam CAD产品在拥有满足快速成型所需的所有强大功能外，可以在同一平台迚行自由的操作，丌需要迚行数据的转换，使用者可以直接、高效、准确的迚行设计不加工，真正的做到快速成型。

3D Printer Buyer’s Guide
1 Introduction 3D Printing Has Come Of Age 3D Printing is more than just prototyping. Today, 3D Printing off ers transformative advantages at every phase of creation, from initial concept design to production of fi nal products and all steps in between. Today’s competitive environment makes choosing the right 3D printers for every phase of creation more important than ever. Just a few years ago in-house 3D printing was enjoyed by only a few professional design engineers and was often limited to printing concept models and some prototypes. Once considered a novel luxury, 3D printing has proven to yield long-term strategic value by enhancing design-tomanufacturing capabilities and speeding time to market. Today, 3D printing technologies have allowed an ever growing number of creators to unleash and multiply the benefi ts of rapid in-house 3D printing across the entire creation process.

一. 经济危机下模具行业面临的挑战、机遇与对策由于工装模具处在制造链条的中游，经济危机对其影响，在今年春节之后开始显现。信心下降-订单减少-开工不足，模具企业的发展甚至生存受到了很大的挑战。但在困境中，我们仍能看到希望：中国的经济环境尚好；中国制造业大国的地位不动摇，模具就不会是夕阳产业。这次危机的正面意义在于，它是一次世界经济系统的刚性调整，大浪淘沙、优胜劣汰。
Read moreOvercoming technology boundaries, taking automation further
Zimmer&Kreim demonstrates the new shuttle station in action at the AMB Processing electrodes and workpieces beyond technological boundaries – this is still a dream of the future in many businesses today. In this respect, the new shuttle station can be something like the missing link, which not only overcomes technology boundaries, but also connects production areas with each other. Zimmer&Kreim presents this pioneering new development at this year’s AMB. This is the status quo in many businesses in the tool and mould industry: A combination of different tasks requires the use of various technologies. This is a major challenge particularly in small businesses. The start into automation initially seems hardly feasible due to the complexity involved. With the Chameleon, Zimmer&Kreim offers a modular start into automation – individually tailored for any company size. At this year’s AMB the Brensbach engineering specialist has taken a further consistent step in this direction, enabling with the innovative shuttle station the combination of different technologies in small as well as large contexts. The intelligent hardware unit along with the intelligent job manager makes ensure that different technology cells communicate with each other and share resources. Automation is therefore possible at every development stage –
