In depth analysis of 5 problems to be solved in the 3D printing industry

British scientists printed out the terminator manipulator; Japan's annual budget application supports the technical research and development of 3D printing metal products; 3D printing allows French patients to regain their noses. The above information was found at the time of publishing on the 15th. If you chat with people about 3D printing, please pay attention to reserve your conversation in time, because the updates on this topic are in hours

recently, Xiyuan salon with the theme of the current situation and development trend of 3D printing technology in China was held in Beijing. Academicians, experts, scholars and representatives of entrepreneurs from famous universities, research institutions and industries at home and abroad, all learn from each other and interact

a three-dimensional picture for 3D development status and application needs has been restored

interpreting 3D printing identity

the core manufacturing idea of 3D printing material superposition originated in the United States. A man named Carlo baese, in his research patent, proposed to use photosensitive polymers to make plastic parts. This was a long time ago, as early as 1902

have you heard of additive manufacturing

just as you may not know that Alzheimer's disease is Alzheimer's disease, 3D printing is actually a popular and vivid concept, which is generally called additive manufacturing, stacking manufacturing, incremental manufacturing or rapid prototyping manufacturing in academia. Now, this technology refers to the digital manufacturing technology based on the forming principle of discrete materials stacking layer by layer, according to the three-dimensional CAD model of the product, through software and numerical control system to stack and solidify the special materials layer by layer to produce solid products

this is a comprehensive and systematic technology that integrates computer software, materials, machinery, control, network information and other multidisciplinary knowledge. In principle, the whole process generally includes five kinds of links: first, product 3D modeling, second, slice data generation and transmission, third, beam scanning material layer by layer, fourth, material melting, and fifth, material stacking layer by layer

3D printing technology can be roughly divided into powder material high-energy beam sintering or melting forming, filiform material melting deposition (FDM), liquid resin solidification forming, and liquid ink-jet printing forming according to the process equipment and materials used and played very different every time

three stages of 3D printing

if it is really (useful), then my Guo character is written upside down. Gou Taiming, a manufacturing tycoon and chairman of Hon Hai, commented on 3D printing technology at the end of June this year. Of course, this statement is not to deny the technology in essence. Whether its environmental protection bag is environmentally friendly or not. Enterprises used 3D printers 30 years ago, but this technology has not been able to help them produce a large number of industrial products. Modern cars or household appliances were born on the assembly line. At present, we cannot expect printers to replace the assembly line

3d printing certainly has a stage to show its talents. First, the rapid manufacturing of complex structures. Theoretically, as long as we can design a three-dimensional structure model, we can quickly turn the design into a real object without tools, molds and complex process conditions; Second, personalized customization. 3D printing is very suitable for personalized customization production, small batch production and verification product manufacturing before product finalization; Third, 3D printing technology is currently mainly applicable to the manufacturing of high value-added products, personalized products, and R & D and design verification before mass production

the application field expanded from high-end to popularization

the 1990s was a period of vigorous development of 3D printing technology, and at least a dozen new processes and new system equipment were introduced successively, but their popularity was still after Obama proposed the strategy of revitalizing the manufacturing industry

the rapid development and high attention of this speed can be seen from the media frequently. Its development is also reflected in all links and levels of this industry

the first is to change from indirect manufacturing after each experiment, such as rapid prototyping and process assistance, to direct manufacturing of parts. In recent years, 3D printing technology using powder materials has become a research hotspot and frontier in the field of direct component manufacturing. Among them, the selective laser melting technology (SLM Technology) equipment using low-power lasers and powder bed technology has only appeared for twoorthree years, but it has shown strong technical advantages in the rapid manufacturing of special alloy parts such as titanium alloys and nickel base superalloys. The secondary load-bearing structural parts manufactured by American aeromet company using lens technology have been installed on F-18 fighter aircraft

next is the interdisciplinary and integrated development, and the application field of 3D printing continues to expand. The cross integration of 3D printing with biology, information and materials provides a broader space for the development of 3D printing technology. The combination of 3D printing technology and bioengineering has been successfully applied to the remanufacture of human organs

third, 3D printing equipment is developing towards productization, serialization and specialization. Improving the forming accuracy and efficiency of parts is the goal of productization, serialization and specialization

fourth, a relatively complete 3D printing manufacturing industry chain has been formed, and a certain industrial scale and market sales have been formed. European and American countries have formed a relatively complete industrial chain including material preparation, related software, technology, equipment, management, creative services and applications. According to the statistics of Wohlers Report 2010, 3D printing applications include consumer products/electronic products industry, automotive industry, medical/dental industry, aerospace, construction and other industries. It is predicted that by 2025, the potential economic impact of 3D printing technology will reach 230250billion US dollars

what is most relevant to our life is that 3D printing equipment has moved from high-end to popular. The sharp increase in the sales of low-end 3D printing equipment has promoted the rapid growth of the total sales of 3D printing equipment, which also shows the rapid transformation of 3D printing manufacturing equipment from high-end to popular. Now on Taobao, you can buy a 3D printer at the cheapest price of several thousand yuan. If you can't wait to try printing out your own model, you can consider buying one

China is basically synchronized with foreign countries

since the early 1990s, China has begun to study this technology with the support of the National Natural Science Foundation of China and the Ministry of science and technology. Compared with other manufacturing fields, 3D printing technology in China is basically started and developed synchronously with foreign countries

especially with the continuous support of several five-year plans of the Ministry of science and technology, a number of scientific research institutions such as Huazhong University of science and technology, Xi'an Jiaotong University, Tsinghua University, Beijing University of Aeronautics and Astronautics, and Northwest University of technology have carried out almost all mainstream 3D printing technology research, developed a number of 3D printing equipment, and established two national key laboratories, a national engineering center, and several productivity promotion centers in aviation, automotive The application verification in biology, electronics and other industries has laid a good foundation for continuous research and application promotion

in addition, DPCA, Changan Ford, Chery, Guangxi Yuchai Machinery Co., Ltd., Dongfeng Motor Company and other enterprises use 3D printing technology in the design, development and production application of a variety of parts and products

in the next five years, China can focus on two categories of objects: high-end industrial products and mass personalized consumer products, strengthen the research on the basic theory and forming micro mechanism, design method, key process technology related to 3D printing, the development of high-performance, high-precision and high-efficiency process equipment, and the formulation of relevant standards and specifications
