3D printing is a manufacturing method combining different energy sources with CAD / CAM, which has the basic characteristics of material accumulation. 3D printing is one of the most important technologies. The characteristic of 3D printing is to use CAD directly for 3D model manufacturing, without intermediate manufacturing process such as mould.

　　3D打印是工业制造业的一场革命。3D打印的工业化意味着产品上市速度更快，制造灵活性更大，产品质量更好，生产效率更高。西门子在增材制造在实际生产中的应用方面具有丰富的实践经验。采用NX软件设计了西门子高温合金燃气轮机的3d打印叶片，交付时间缩短了75%，成本降低了70%，效率降低了0.1%。

　　3D printing is a revolution in industrial manufacturing. The industrialization of 3D printing means faster product launch, greater manufacturing flexibility, better product quality and higher production efficiency. Siemens has rich practical experience in the application of additive manufacturing in actual production. The 3D printing blade of Siemens superalloy gas turbine is designed with NX software. The delivery time is shortened by 75%, the cost is reduced by 70%, and the efficiency is reduced by 0.1%.

　　由于3D打印制造在原理上不需要模具，设计师可以在保证产品性能的前提下，设计出更复杂的零件，减少零件数量，优化装配工艺，大大缩短了原型制造周期，加快了产品推向市场的速度?？傻魃杓苹箍梢月憧突Фㄖ菩枨螅蚧肺ち鞒?。西门子NX端到端单一集成软件涵盖了设计、优化、模拟和打印功能，同时还兼容金属和塑料部件的设计，为客户提供增材制造应用的集成解决方案。

　　Because 3D printing manufacturing does not need mold in principle, designers can design more complex parts, reduce the number of parts, optimize the assembly process, greatly shorten the prototype manufacturing cycle, and speed up the product to the market on the premise of ensuring product performance. The adjustable design can also meet the customer's customized requirements and simplify the product maintenance process. Siemens NX end-to-end single integrated software covers design, optimization, simulation and printing functions, and is compatible with the design of metal and plastic parts, providing customers with integrated solutions for additive manufacturing applications.

　　汽车工业是更早实现3D打印的行业之一。在过去的十年里，的技术革新了汽车的开发、设计、制造和销售。更、更轻的产品，全新的设计，更低的制造成本，更快的开发和制造已成为行业的发展方向。

　　The automobile industry is one of the first industries to realize 3D printing. In the past decade, advanced technology has revolutionized the development, design, manufacture and sale of automobiles. Safer and lighter products, new design, lower manufacturing cost, faster development and manufacturing have become the development direction of the industry.
