机械工程学院毕业设计外文翻译 题 3D printer design introduction With the progress of the times, our standard of living is increasing, at the same time, the population is growing rapidly, we need more and more items to meet the conditions of material life. This certanly will cause our requirements for goods will be more and more high, fine workmanship, unique and non production items will be affected by the broad masses of peoples favorite. Now, we have the advanced technology of 3D printing, and we can print all kinds of what we need and want through the 3D printer. 3D printing technology applications, it can be used in the medical industry, scientific research, product model, architectural design, manufacturing and food and so on, a wide range of prospects. 3D printing technology, is based on a digital model file, the use of powdered metal or plastic and other materials can be bonded by layer by layer, the way to construct the object technology. 3D printer appeared in the 90s of last century, that is, the use of light curing and paper laminating technology, such as rapid prototyping. It is basically the same with ordinary printer working principle, printer equipped with liquid or powder and other printed materials , and computer connection, through the computer control to print materials a superimposed layers. At last, the computer on the blueprint into the physical. Now this technology has been applied in many fields, people use it to make clothing, building models, cars, chocolate desserts, etc.. 1.1 research status of 3D printers at home and abroad Research status of 1.1.1 foreign 3D printer After more than ten years of exploration and development, 3D printing technology has made considerable progress, at present, it has been able to achieve the fine resolution of 600dpi in the single layer thickness of 0.01mm. At present, the international advanced products can achieve the vertical rate of 25mm thickness per hour, and can realize the color of the 24 color printing. Currently, in the global 3D printer industry, the United States Systems 3D and Stratasys two companies to occupy the vast majority of the market share. In addition, in this field has a strong technical strength and characteristics of the enterprise, Systems 3D is the worlds largest rapid prototyping equipment development company. In November 2011 acquired the first inventor of the 3D printing technology and the original patent owner Corporation Z, Systems 3D has laid a leading position in the field of 3D printing. Stratasys company in 2010 with the traditional printing industry giant Hewlett-Packard Co signed a OEM cooperation agreement, the production of 3D brand HP printer. Following the acquisition of Solidscape in May 2011, Stratasys in April 2012 with Israels famous 3D printing system provider Objet announced the merger. At present, the international 3D printer manufacturing industry is in a rapid merger and integration process, the in
