Design technical route
As an emerging technology, 3D printing may bring some potential hidden dangers to economic and social management while leading a new round of technological revolution. Cao Gang, deputy inspector of the Equipment Industry Department of the Ministry of Industry and Information Technology, said that the loss of control of technology may lead to the deterioration of social security, bring new challenges to intellectual property protection, pose a potential threat to consumer rights, and bioprinting may have an impact on traditional ethics.
In order to guide the healthy and orderly development of the industry, it is especially important to design a technical development route. Lu Bingheng believes that the technological development direction of the additive manufacturing industry should be from 3D printing to 4D printing (smart materials and structures), and then to the direction of 5D printing (biomaterials and active organ reconstruction).
From an international perspective, the US federal government and enterprises have invested US$70 million to support the development and application of additive manufacturing technologies. The United Kingdom, Germany, Canada, Japan and other countries have also promoted the development and industrialization of 3D printing technology by establishing 3D printing research centers and formulating 3D printing technology standards.
The sales value of China's 3D printing industry last year was 600 million yuan. At present, in the field of metal additive manufacturing, Beijing University of Aeronautics and Astronautics and Northwestern Polytechnical University have made major breakthroughs in the field of laser direct forming technology for high-performance metal parts. However, in terms of non-metallic additive manufacturing, China's 3D printing technology is still in the initial stage of industrialization. The key technologies and products such as equipment manufacturing, material preparation, software development and process control, and core components have not yet achieved substantial results. Breakthrough; the standard system needs to be established; to achieve large-scale industrialization, it is necessary to continuously improve manufacturing precision and production efficiency; industry organizations need further development.
"With the overall transformation and upgrading of China's manufacturing industry and the rapid development of aerospace, medical equipment and other industries, the demand for 3D printing equipment and services will continue to expand."
