On June 10th, the "2023 China Economic Media Conference" was held in Shaoxing, Zhejiang Province, jointly sponsored by China Economic Media Association and Shaoxing Municipal Government of Zhejiang Province, with the theme of "Promoting Chinese Modernization and High-Quality Development", and hundreds of representatives from the national economic circles, media circles and enterprises gathered together to interpret the current economic situation and challenges, analyze the opportunities for development in the digital era, and talk about the path of deep integration to unite the majestic power, Hundreds of representatives from the economic, media and business sectors gathered together to interpret the current economic situation and challenges, analyze the development opportunities in the digital era, talk about the path of in-depth integration, and gather the majestic force to promote Chinese-style modernization and high-quality development.

In the economic forum held in the afternoon, famous digital economy experts and scholars, corporate guests, media representatives, etc., jointly carried out in-depth interpretation and discussion on the topics of promoting the realization of the deep integration of the real industry and digital technology development. Dr. Zong Guisheng, Chairman of Beijing SANDI Technology Co., Ltd. and "2018 China's economic newsman", was invited to give a speech entitled "Starting from 3D printing, upgrading manufacturing with digital technology" in the forum, sharing the important application of 3D printing in the digital transformation and upgrading of traditional manufacturing, and pointing out that, after years of development, 3D printing has become an important part of digital transformation. 3D printing has become an important tool for digital transformation.

Today's global development megatrends are changing the lives of enterprises and individuals, in which industrial companies by the "digital, mobility, everything is a service" trend of the direct impact of digital technology to promote the upgrading of the traditional manufacturing industry and manufacturing services is the direct embodiment of the impact of these megatrends on the industrial sector. In recent years, 3D printing digital technology has promoted the casting, injection molding, hand plate industry digital manufacturing progress.

Changes in manufacturing process methods also reflect the general trend of digital development: mechanical features of equal material manufacturing, including casting, forging, welding, etc., has a history of nearly 3,000 years; automated features of the subtractive casting, including turning, milling, grinding, etc., the development of nearly 300 years; and digital features of additive manufacturing (i.e., 3D printing), including selective laser fusion, selective laser curing, binder jet, etc., the introduction of also has been more than 30 years.The composite application of 3D printing and traditional manufacturing processes is an important part of the digitalization of the manufacturing industry.

3D printing digital manufacturing technology after more than 30 years of development, the industrialization of its application of global compound annual growth rate in 20% above, China is even higher, but because of its output value base is relatively small, 3D printing industry, despite the significance of the industry so far, but it is still a small industry. 3D printing industrialization is slow because of the main reason for the low efficiency of the printing, that is, the slow speed of manufacturing; the second is the printing material is expensive, that is, the high cost of manufacturing. High cost. A slow and expensive technology is difficult to be applied to the production line, which is why most of the main users of 3D printing equipment are research institutes, R & D departments of large companies, schools and 3D printing service organizations.

In order to solve the problem of slow and expensive traditional 3D printing, 3D Printing 2.0 Binder Jet process has emerged. 3D printing 2.0 binder jetting BJ process using "line scanning" technology is a high-efficiency, high-precision additive manufacturing technology, which follows the traditional powder metallurgy industry's material system and sintering process, low cost, high degree of standardization of materials, can provide industry with high-efficiency, high-quality, low-cost metal additive manufacturing solutions, can be applied to the production line, laying a solid foundation for the large-scale application of 3D printing technology. manufacturing solutions that can be applied to production lines, laying a solid foundation for the large-scale application of 3D printing technology. With the continuous expansion of 3D printing applications, it is expected that 3D printing 2.0 more will bring breakthroughs for the 3D printing industry to continue to grow, especially in helping traditional manufacturing upgrading, the performance will gradually appear.

At present, the global 3D printing market is rapidly expanding on the basis of hundreds of billions of dollars. The global 3D printing industry structure in 3D printing services accounted for the highest proportion, while the Chinese market 3D printing equipment accounted for the highest proportion, visible in the future of China's 3D printing application market has great potential. From the perspective of the overall industry pattern of China's machinery manufacturing, iso-materials manufacturing market over a trillion, the largest scale; subtractive manufacturing market in about 500 billion; and additive manufacturing is currently in the 30 billion or so, but the growth is very fast, especially the emergence of 3D printing 2.0, accelerating the composite manufacturing (such as additive and subtractive, additive forging and subtractive, etc.) and the digitalization to upgrade the rhythm of traditional manufacturing, the hundreds of billions of dollars of the market can be expected soon.

Take the casting industry as an example. China is the world's largest casting country, there are about 400 billion market size, the global share of 45%, there are more than 24,000 foundries, maintaining steady growth, but there is a high energy consumption, high pollution, not strong, not fine. To this end, China's 14th Five-Year Plan specifies the digital upgrading and other development goals, proposed to use 3D printing to achieve sand casting digitalization, greening, the establishment of more than 200 demonstration green casting plant. April 14 this year, the Ministry of Industry and Information Technology, Development and Reform Commission, the Ministry of Environmental Protection also jointly issued a document to promote the integration of die-casting molding, moldless casting, sand 3D printing and other advanced process technologies to achieve industrialization and application.

Through the analysis of the foundry industry, it is more profound understanding of the urgency of numerical upgrading of the foundry industry. Some statistics, the national casting annual output of castings more than 10,000 tons of casting enterprises more than 1,000, more than 50,000 tons of nearly 200 enterprises. The head of more than 2,000 casting production accounted for the national total production capacity of more than 55%. The head of the lack of customization or small batch trial production capacity, the development of new products is slow, high cost; "long tail" low capacity utilization, most of the enterprises to be eliminated; only the "long tail" in the head of the enterprise, relying on 3D printing and automation rate increase after the Only the head of the "long tail" enterprises, after relying on 3D printing and automation rate increase, can survive, and there may be several times the concentration of the space.

Under this major opportunity of transformation and upgrading, SANDI Technology decisively laid out, on the basis of mastering the core equipment, materials and process technology of 3D printing 2.0, and through the merger and acquisition of the foundry, it directly opened up the 3D printing process and casting process. At the same time, 3D printing 2.0 technology is applied to enhance the powder injection molding, forming the competitive ability of 3D printing digital casting and powder metallurgy molding, and successfully creating a multi-material, full-size, full-chain service model. The current customers include head enterprises in aerospace and military industry, automobile and other fields such as China Aerospace Development, Weapon Group, Yuchai, Geely Automobile, etc., radiating many customers in the field of machinery manufacturing, with a high rate of repurchase and strong growth.

3D printing digital casting, no need to open the mold, from the three-dimensional data design, to the casting mold direct printing, and then casting, significantly shorten the new product development cycle, reduce costs. Adopted 3D printing digital process foundry, its production modeling changes, significantly reducing energy consumption and pollution, improve the working environment, enhance the value of the product attachment and finished product rate, so that the complex parts of the rapid, high-precision, green casting has become possible. For example, automotive engine block new product development, the traditional casting production cycle takes 3-4 months, if you want to modify, you have to change the mold or even reopen the mold, time-consuming will be longer. The use of 3DP sand printing rapid casting, two weeks to deliver finished aluminum alloy castings, if you want to modify, you only need to modify the data, the overall cost from a million dollars down to tens of thousands of dollars.

With the 3D printing 2.0 brought about by the improvement of printing efficiency and cost reduction, 3D printing in batch casting applications will further expand the proportion of 3D printing technology will promote the traditional casting upgrade to become a green digital fast casting, and drive the majority of foundry enterprises transformation and upgrading.

In the roundtable dialogue session of the forum, Dr. Zong Guisheng, together with the heads of the China Urban Development Research Association, Chianxin Technology Group, NextHuman Vantage Technology and other leaders, talked and explored topics such as the development mode and path of the in-depth integration of industrial digitization and the real economy, the optimization and upgrading of industrial structure under the reshaping of the demand side of the digital economy, and exploration of the Chinese program of digital transformation.

According to the World Hearing Report 2021 released by the World Health Organization, there are about 1.5 billion people around the world who are suffering from hearing impairment. According to statistics, there are 72 million hearing impaired people in China, including about 60 million elderly people, but the market coverage of hearing aids is less than 5%. At present, most of the domestic mid- to high-end hearing aid market is monopolized by imported brands, accounting for about 90% of the market share; and most of the local hearing aid companies are difficult to meet the market demand for miniaturized, personalized and intelligent hearing aid products. In addition, most of the hearing aid products in the market are made of UV-cured materials (polymers containing vinyl), which provides a relatively single option and low wearing comfort, while hearing aid products equipped with customized metal shells (e.g., titanium alloy) with better performance have been monopolized by foreign brands for the time being, and the prices are high.
