At that time, 3D printing was regarded as incremental and new kinetic energy. After 5 years, many people think that it has become a thing of the past. In fact, the application of 3D printing has just begun." "2019 Guangdong 3D Printing Industry Held in the Canton Fair Pavilion" "Application Summit Forum", a 3D printing industry representative said in a speech.
On December 1st, in order to promote the development of the industrialization of 3D printing technology, under the guidance of the Guangzhou Municipal Bureau of Industry and Information Technology, the RoboIMEX Organizing Committee and the Guangdong Additive Manufacturing Association jointly sponsored the Guangzhou Shenglong Industrial Design Technology Park. The "2019 Guangdong 3D Printing Industry Application Summit Forum" hosted by Development Co., Ltd. (Guangzhou 3D Printing Industry Park) was held in the Guangzhou Canton Fair Complex. The forum and exhibition brought together a number of academicians, experts, industry elites, and business representatives to showcase domestic and foreign additives Achievements of technological advances in manufacturing industry advanced technologies and product application cases.
"Father of 3D Printing in China" Lu Bingheng:
Suggest that Guangdong focus on applying 3D printing to wearable electronic devices, new energy vehicles and other fields
Known as "the father of 3D printing in China", Lu Bingheng is an academician of the Chinese Academy of Engineering, a professor and doctoral supervisor of Xi'an Jiaotong University, the director of the National Engineering Research Center for Rapid Manufacturing, and the honorary chairman of Guangdong Additive Manufacturing Association. He introduced in his speech that in recent years, the global 3D printing industry has shown rapid development. The current global market size has reached 9.2 billion U.S. dollars. According to China's statistics, China's current 3D printing market size is 3.18 billion yuan, accounting for 1/3. Looking at the situation, China's 3D printing equipment increased by 271.24% in the first half of this year. He also introduced that additive manufacturing (3D printing) technology has five arbitrary advantages, that is, any material, any shape, any batch, any field, any place, and is currently widely used in model development, building construction, biomedical, aviation Aerospace, power machinery, personalized design and other fields.
According to incomplete statistics from China's Additive Manufacturing Industry Alliance, at present, the output value of 3D printing in Guangdong Province has accounted for one-third of the country. "Guangdong is the frontier of reform and opening up, and is very sensitive to new technologies. It is the forefront of 3D printing technology applications." Lu Bingheng said, however, due to the developed manufacturing industry in Guangdong, 3D printing is still the most widely used prototype field, and even has The situation of overcapacity and excessive competition "because some people think it is the past tense".
Regarding the application direction of 3D printing in Guangdong, he suggested that we can focus on three aspects: the first is the field of electronics manufacturing, and the Pearl River Delta has a solid foundation in mold manufacturing; the second is the field of wearable electronic devices, such as headphones and glasses, because Everyone's wearable devices are different and need to be customized. The third is the automotive field, especially new energy vehicles, which are pursuing lightweight. Some car companies are trying to use composite materials. 3D printing technology has a lot of space. It is understood that Lu Bingheng's research field focuses on the application of 3D printing technology in the military field. According to the industrial situation in Guangdong, he intends to establish a 3D printing research institute in Guangdong for targeted research and development.
Lv Jian, Member of French Academy of Technical Sciences:
The world's first ceramic 4D printing was achieved last year "3D printers will enter ordinary homes like cameras"
With the development of 3D printing technology, the exploration of 4D printing has appeared in this field, that is, on the basis of 3D printing, a time dimension is added so that under certain stimuli (such as heat, water, magnetic fields, current, ultraviolet rays, etc.), The shape and function of 3D printed objects change over time. Last year, Lv Jian, an academician of the French National Academy of Technical Sciences and a professor of mechanical engineering at the City University of Hong Kong, led his team to achieve the world's first ceramic 4D printing, which caused widespread concern. It is reported that the melting point of ceramics is very high, and it is very difficult to produce ceramics by conventional laser printing technology. However, the ceramic precursors produced by the existing 3D printing technology are often difficult to deform, which affects the production of ceramic products with complex shapes. The "ceramic ink" made by mixing objects and ceramic nanoparticles, the ceramic precursor printed with it is very soft, making ceramic 4D printing possible. After more than a year, he came to this forum with the latest research results of 4D printed ceramics, and gave a keynote speech on "2D-3D-4D printing: principles, processes and applications in biomedical, 3C and aerospace."
"This year, we were studying 4D printed works of water control, magnetic field control, and light control (that is, to change the shape and function of 3D printed works under the stimulation of water, magnetism, and light). We also cooperated with the Institute of Materials of Guangdong Academy of Sciences, The fatigue strength of the 3D printed prosthetic titanium alloy has been doubled, so that its life can be extended to infinity. "Lu Jian introduced the team's research results over the past year. Earlier, he mentioned that ceramic 4D printing can be applied to the back panel of mobile phones. Especially after the mobile phone enters the 5G era, it can avoid signal shielding problems like glass and plastic, and it will not be too heavy and high-end. As 5G mobile phones are slowly gaining popularity, he said that they will develop ceramic mobile phones within 2 years.
As a leading expert in 3D printing in the Greater Bay Area, he always looks for the application of research results in the Greater Bay Area, especially in the four major cities of the Greater Bay Area. He believes that the Greater Bay Area has incomparable advantages in the flow of talents, funds, and technology. "Guangdong's ceramic industry alone has a market size of 30 billion, and mobile phone manufacturing and other industries have broad application prospects." Lu Jian also believes that popularization is the development trend of 3D printing. The cheapest 3D printing equipment today is only two or three thousand yuan. In the future, it will enter ordinary families like cameras and printers. By then, everyone can become a 3D printing designer and personalized manufacturing. Therefore, the traditional plastic die-casting industry is deconstructed.
Brain hole wide open: 3D printed stone lions, insoles, etc. on display
In addition, Professor Yang Yongqiang of South China University of Technology, Professor Leng Jinsong of Harbin Institute of Technology, Professor Wang Yungan of Huazhong University of Science and Technology and many other 3D printing experts and industry representatives delivered special lectures on application analysis and bottleneck breakthroughs in 3D printing.
The additive manufacturing (3D printing) technology and equipment exhibition held at the same time as the summit forum is a professional exhibition platform for 3D printing exhibitors to display the leading 3D printing technology and equipment in China. Leijia Additives, Jiehe Electronics, Shanchuang Automation and many other well-known domestic and foreign enterprises and units are committed to presenting the latest and most complete additive manufacturing industry chain products and technologies, including rapid prototyping, CAD / CAM software development, education and training , Mold manufacturing, 3D laser engraving, industrial and desktop 3D printers and related accessories.
During the exhibition, the reporter learned that there are many 3D printed items with wide brains and practicality. For example, 3D printed stone lions, transparent violin, customized insoles based on the differences in human arches, engines that facilitate heat dissipation, etc. In addition, there are 3D printing devices of different sizes and different principles that attract many people to stop and watch the experience.
