Wang Huaming: there is a broad space for 3D printing to improve the technical level of equipment

Guide: everyone in China can think so. The research and application of high-performance large-scale metal component additive manufacturing/3d printing technology is at the forefront of the world. This technology is of great significance to improve the R & D and manufacturing level of major high-end equipment in China. In the future, 3D printing technology will have broad development space in the field of manufacturing key components of high-performance metal materials

since this year, the topic of 3D printing has increasingly become the focus of attention of all sectors of society: what is the current development status of 3D printing technology in China, what is its international level, and what is the future development space? At the 2013 Zhongguancun forum annual meeting held not long ago, Wang Huaming, a professor at Beijing University of Aeronautics and Astronautics, said in an exclusive interview that China's research and application of additive manufacturing/3d printing technology for high-performance large metal components are at the forefront of the world. The specific scheme of applying computer measurement and control technology to traditional presses is of great significance to improving the R & D and manufacturing level of major high-end equipment in China. In the future, 3D printing technology will have broad development space in the field of manufacturing key components of high-performance metal materials

it is understood that additive manufacturing refers to the technology of manufacturing solid parts by gradually accumulating materials, commonly known as 3D printing. Compared with the traditional material removal processing technology, it is a bottom-up manufacturing method. In the past 20 years, additive manufacturing technology has achieved rapid development. It has different titles in the industry, such as rapid prototype manufacturing, three-dimensional printing, solid free manufacturing, rapid prototyping, direct manufacturing and so on

Wang Huaming said that 95% of the graphite in the European Union, such as Xi'an Jiaotong University, Tsinghua University, Huazhong University of science and technology and Beijing Longyuan company, came from China in the early 1990s. Research on Rapid Prototyping/3d printing technology and industrial application began in the mid-1990s. Research on Laser Rapid Prototyping of high-performance metal parts also began in the mid-1990s. At present, technology research and development and engineering applications also have international advantages. According to him, the practical application of 3D printing technology can be roughly divided into two levels: first, in the field of non-metallic 3D printing, 3D printing technology has been widely used in the process of new product design and development; Second, in the field of additive manufacturing of high-performance metal parts, China's 3D printing technology has an international leading level and has great development potential in the future. For example, the achievements of laser forming technology of titanium alloy components have been produced by professional enterprises

As a new manufacturing technology, 3D printing is not only an important means of new product research and development, but also can improve the level and performance of equipment manufacturing technology. Each technology has its scope of application. 3D printing of high-performance metal parts is of great value to the manufacturing of major high-end equipment, because it can directly produce parts in equipment. Wang Huaming said

as an expert in manufacturing aircraft titanium alloy components, Wang Huaming has a deep understanding of new materials based on 3D printing technology. He believes that the close combination of new materials and manufacturing is the foundation of the equipment manufacturing industry, and its impact on the future will be greater and greater. In a large field, the core of additive manufacturing of high-performance metal components is to control the additive manufacturing process to obtain components with high-performance and high-quality materials. The goal of additive manufacturing is to obtain high-performance components. Its manufacturing process must be fast, with excellent performance and low cost. We are targeting the direction of additive manufacturing at high-performance materials, which are much larger than titanium alloys. Wang Huaming said

in the competition between China's 3D printing technology and the international advanced level, the more important thing is how to develop application-oriented technology and transform achievements, especially in the industrial field, that is, how to give full play to the advantages of additive manufacturing 3D printing to produce high-end equipment with high performance and high added value. Wang Huaming said that China has both advantages and potential in this regard. Firstly, China attaches great importance to the development of 3D printing technology. Secondly, China has a broad market. Thirdly, China has a large high-level 3D printing research and development team

referring to the relationship between additive manufacturing 3D printing and China's aircraft equipment manufacturing industry, Wang Huaming believes that the manufacturing of high-performance metal materials based on 3D printing technology will bring great value to China's aerospace equipment manufacturing industry. There is a large error value in the number of torsion cycles recorded in the experiment. The implementation of major national aircraft science and technology projects also provides development opportunities for the application of additive manufacturing technology in the aviation industry

the manufacturing industry pays more attention to the development of additive manufacturing of industrial equipment, while the society pays more attention to desktop 3D printing technology. No matter what kind of attention, it is conducive to the popularization of this technology. It is believed that through the creation of more than a billion Chinese people, the great potential of 3D printing will be brought into full play. Wang Huaming said
