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打印是工業(yè)制造業(yè)的一場(chǎng)革命。3D打印的工業(yè)化意味著產(chǎn)品上市速度更快，制造靈活性更大，產(chǎn)品質(zhì)量更好，生產(chǎn)效率更高。西門子在增材制造在實(shí)際生產(chǎn)中的應(yīng)用方面具有豐富的實(shí)踐經(jīng)驗(yàn)。采用NX軟件設(shè)計(jì)了西門子高溫合金燃?xì)廨啓C(jī)的3d打印葉片，交付時(shí)間縮短了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，設(shè)計(jì)師可以在保證產(chǎn)品性能的前提下，設(shè)計(jì)出更復(fù)雜的零件，減少零件數(shù)量，優(yōu)化裝配工藝，大大縮短了原型制造周期，加快了產(chǎn)品推向市場(chǎng)的速度。可調(diào)設(shè)計(jì)還可以滿足客戶定制需求，簡(jiǎn)化產(chǎn)品維護(hù)流程。西門子NX端到端單一集成軟件涵蓋了設(shè)計(jì)、優(yōu)化、模擬和打印功能，同時(shí)還兼容金屬和塑料部件的設(shè)計(jì)，為客戶提供增材制造應(yīng)用的集成解決方案。

　　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.

　　汽車工業(yè)是更早實(shí)現(xiàn)3D打印的行業(yè)之一。在過去的十年里，的技術(shù)革新了汽車的開發(fā)、設(shè)計(jì)、制造和銷售。更、更輕的產(chǎn)品，全新的設(shè)計(jì)，更低的制造成本，更快的開發(fā)和制造已成為行業(yè)的發(fā)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.
