Recently, with the availability of the first domestic industrial casting 3D printing products, the 3D printing industry has once again attracted people's attention. It is understood that 3D printing technology originated in the United States in the mid-1990s and has been widely used in industrial design, architectural design, engineering construction, automobile manufacturing, aerospace engineering, and medical fields. In recent years, with the country's emphasis on the 3D industry, China's 3D printers have developed rapidly. Industry agencies predict that in 2017 China's 3D printing industry will reach 17.3 billion yuan, and by 2021 it will reach 69.1 billion yuan.
China's First Industrial Casting 3D Printing Product Available
Recently, the country's only 3D industrialization base and Sichuan province's major industrial company Sichuan Sharing Foundry Co., Ltd., after two weeks of intense production, has produced the first batch of 3D printing products in the industrial field of casting in China. After being put on the market, it will achieve 3D printing. Applied to the zero breakthrough in the field of casting industrialization.
This batch of products is part of a locomotive engine produced by the shared foundry company for Zhongyang Ziyang. In order to produce this batch of products as quickly as possible, all the machines in the workshop will not stop working for 24 hours from the Spring Festival to the present, and the workers will be on duty 24 hours a day. Because the workshop implements "green manufacturing" and "smart manufacturing", the protagonist of production is no longer a worker, but an intelligent machine. The same amount of production, the number of original hand-casting, more than double the number needed now.
Not only has the labor cost been reduced, the 3D printer has also greatly increased the product yield and achieved energy conservation and emission reduction. Li Zhaoqi, the head of the intelligent manufacturing department of Sichuan Shared Casting Company, said that in the case of cylinder heads on previous engines, the previous finished product rate was less than 100. Sixty percent, after using 3D printing, it will probably increase the yield to more than 95 percent.
Traditional manufacturing is to manufacture molds first, and then to verify the defects of products. This is one of the reasons for the low yield rate. The shared foundry workshop implements “smart manufacturing”, which is changed from the traditional first-mould re-experiment to the use of computers. The product was modeled and manufactured. Experiments and reproduction were conducted first to increase the yield.
It is understood that the shared casting company will formally put into mass production at the end of March this year. It will mainly cast and produce engine power and railroad engine products. The planned production capacity will reach more than 2,000 tons, and the annual production value will reach 300 million yuan.
China's 3D printing industry will reach 17.3 billion yuan in 2017
In the late 1980s, the birth of 3D printers opened a new era of additive manufacturing. In recent years, with a new round of scientific and technological revolutions and industrial changes, 3D printing has entered a period of rapid development. Countries around the world are cultivating it as a new growth point for future industrial development. For example, in 2012, the United States identified “additive manufacturing technology” as the first manufacturing innovation center (later renamed “Made in USA”), the European Union, Japan, and South Korea. Singapore, Russia, South Africa, India and other countries have also adopted various measures to promote the development of the 3D printing industry. China's 3D printing technology is basically in sync with the world's advanced level, but industrialization is still in its infancy.
The research of 3D printing in China started in the 1990s and started in colleges. Now it has formed Yan Yongnian team of Tsinghua University, Wang Huaming team of Beijing University of Aeronautics and Astronautics, Lu Bingheng team of Xi'an Jiaotong University, Shi Yusheng research team of Huazhong University of Science and Technology and Huang Weidong team of Northwestern Polytechnical University. The number of key scientific research forces, papers, and patent applications is the second largest in the world. In October 2016, the China Additive Manufacturing Industry Alliance was established. The National Additive Manufacturing Innovation Center construction program also passed expert demonstration. With the continuous advancement of the reform of China's scientific and technological institutional mechanisms, the road of cooperation in production, education, and research forms a long-term cooperation mechanism, which has become a realistic option for China to promote the industrialization of 3D printing.
It is reported that at present, China has already had some advanced technologies in the 3D printing industry. Among them, laser direct processing metal technology has developed rapidly and has basically met the mechanical performance requirements of special components. In this regard, Huang Weidong's team at Northwestern Polytechnical University used this type of technology to directly manufacture metal parts and has successfully remanufactured aeroengine blades. At the same time, Beijing University of Aeronautics and Astronautics professor Wang Huaming led the "laser alloy large-scale complex monolithic laser forming technology", so that China's high-performance metal materials in the 3D printing, among the world's leading ranks, and now has been widely used in China's aerospace field.
On August 23, 2016, the Ministry of Housing and Urban-Rural Development released the “Outline for the Development of Informatization in the Construction Industry 2016-2020”, which proposed to actively carry out research on 3D printing equipment and materials for the construction industry, and explore the application of 3D printing technology to the production of building parts and components and development. Demonstration application. This means encouraging the recognition and promotion of 3D printed building technology at the national level.
Using 3D printing technology will be a subversive revolution for real estate. In the future, customers can not only customize the home, but also can customize the personalized house, print a variety of special-shaped components, so that a suite of a design. The buildings in the community do not need to be stereotyped, on the basis of maintaining style coordination.
In most people's minds, 3D printing only exists in high-tech fields. However, with the increasing perfection of 3D printing construction technology, especially the successful application of 3D printing construction technology in the construction industry, the industrial transformation led by 3D printing construction technology is expected to become the future direction of the construction industry and real estate industry.
The report hall "2016-2021 China 3D Printer Industry Market Demand and Investment Advisory Report" predicts that in 2017 China's 3D printing industry will reach 17.3 billion yuan, and the average annual compound growth rate will be about 41.36% over the next five years (2017-2021). In 2021, the industrial scale will reach 69.1 billion yuan.
