[ppzhan Abstract] 3D printing has become the focus of the world's attention. In the face of this new technology known as the third industrial revolution, the world is known as "the madness." My country is no exception. However, some recent comments indicate that the 3D printing technology industry may face bottlenecks in development. Therefore, in the early stage of development, it is necessary to deepen reform, independent innovation, and focus on scientific and technological research and development.
3D printing technology as an emerging technology in the field of rapid prototyping, and now the world's hot technology has become the focus of attention. Many news media are optimistic that the 3D printing industry will become the next sunrise industry with broad prospects, but it will take 5-10 years for 3D printing technology to mature to meet market demand. In this relatively long development process, the industry may face risks such as failure of growth expectations, bottlenecks in technology, and withdrawal of investment. Therefore, at this stage, we must strengthen innovation and research and development, technology introduction and reserve, especially pay attention to the construction and maintenance of independent intellectual property rights, and strive to occupy a favorable position in the future market competition.
3D printing technology 3D printing technology refers to the technology of generating three-dimensional solids by layer-by-layer material addition through continuous physical layer superposition. It is different from traditional material removal processing technology, so it is also called Additive Manufacturing (AM). As a comprehensive application technology, 3D printing integrates cutting-edge technical knowledge in digital modeling technology, electromechanical control technology, information technology, materials science and chemistry, etc., with high scientific and technological content. The 3D printer is the core equipment for 3D printing. It is a complex mechatronic system integrating mechanical, control and computer technology. It is mainly composed of high-precision mechanical systems, numerical control systems, injection systems and molding environments. In addition, new printing materials, printing processes, design and control software are also important components of the 3D printing technology system.
At present, 3D printing technology is mainly used in the fields of product prototype, mold making, art creation, jewelry making, etc., replacing the fine processing technology traditionally relied on in these fields. 3D printing can greatly improve the efficiency and precision of production. In addition, in the fields of bioengineering and medicine, construction, clothing, etc., the introduction of 3D printing technology has also opened up a vast space for innovation. For example, in 2010, Australia Invetech and the United States Organovo company, trying to print the human body tissues and organs with living cells as "ink" is a significant innovation in the medical field.
The development status of 3D printing technology and industry in China Since the 1990s, many universities in China have carried out independent research and development of 3D printing technology. Tsinghua University has certain scientific research advantages in modern molding theory, layered entity manufacturing, FDM technology, etc. Huazhong University of Science and Technology has advantages in layered physical manufacturing processes, and has introduced HRP series molding machines and molding materials; Xi'an Jiaotong University independently developed a three-dimensional printer nozzle, and developed a photo-curing molding system and corresponding molding materials, with a molding accuracy of 0.2 mm. The University of Science and Technology of China has developed an eight-nozzle combination jetting device, which is expected to be applied in the field of micro-manufacturing and optoelectronic devices. But overall, the level of domestic 3D printing technology research and development is still far from the foreign countries.
In recent years, domestic companies such as Shenzhen Wei Shi Taike, Nanjing Zijin Lide, Beijing Yinhua, Jiangsu Dunchao have realized the production and sales of 3D printers. The common features of these enterprises are established by overseas returning teams. Smaller, product technology is still at the low end compared with similar products from foreign manufacturers. At present, domestic 3D printers are still difficult to meet commercial needs in terms of printing accuracy, printing speed, print size and software support, and the technical level needs to be further improved. In the service field, enterprises in the eastern developed cities of China have developed commercial rapid prototyping services using imported 3D printing equipment. The service scope covers mold making, sample making, auxiliary design, and cultural relics restoration. Compared with the mainland, the introduction of 3D printing technology in Hong Kong and Taiwan has started earlier and is more widely used. However, Hong Kong and Taiwan mainly focus on technology applications rather than independent research and development.
Future development prospects of the 3D printing industry It is predicted that in the next few years, the 3D printing industry will continue to grow rapidly. By 2016, the total industrial output value including equipment manufacturing and services will reach US$3.1 billion, and will be 2020. It reached $5.2 billion. However, at present, the industry is still far away from the mature stage. Therefore, at this stage, the industry should invest more in innovation and R&D, technology introduction and reserve in the field of 3D printing, especially paying attention to the construction and maintenance of independent intellectual property rights. The future market competition has a favorable position. If it is affected by the concept of speculation, large-scale investment in capacity expansion at the current stage of technology is not fully improved, it will face greater risks.
