"The key to the development of 3D printing is materials. The future 3D printing materials will have a huge vitality and may occupy more than 30% of the 3D printing output value. We must make a big article on 3D printing materials to narrow the gap with the international." December 18 On the day of the inaugural meeting of the China 3D Printing Materials Council, Zhou Lian, academician of the Chinese Academy of Engineering and chairman of the China 3D Printing Materials Council, said.
Zhou Lian pointed out that most of the polymer materials and metal materials used in the 3D printing industry rely on imports, subject to people, and the price remains high, which seriously hinders the market application and promotion of 3D printing in China. People pay too much attention to 3D printing equipment and ignore 3D printing materials. Therefore, the establishment of China 3D Printing Materials Council has played a significant role in the development of China's 3D printing industry. To narrow the gap between China's 3D printing and foreign countries, the materials industry must join hands to make early arrangements and seize opportunities.
Ge Changchun, an academician of the Chinese Academy of Sciences, said that the development of China's materials industry requires the state to increase financial support. At the same time, it will effectively integrate the resources of major R&D institutions, materials companies and 3D printing companies, and realize the close integration of “government, industry, research and research†to achieve The breakthrough of China's material industry.
Luo Jun, executive director of China's 3D printing technology industry alliance, believes that although there are more than 1,000 materials used in 3D printing, it is far from enough compared with traditional manufacturing. Some metallurgical powder materials such as nylon materials, ceramic materials, photosensitive resin materials and titanium alloys, we basically rely on imports, seriously affecting the healthy development of China's 3D printing industry.
"We are not only lagging behind in metal 3D printing and bio-3D printing equipment, but the gap in the material field is further widening. In the next step, we must actively support a group of materials companies to cooperate with domestic and foreign scientific research institutions to realize 3D printing materials as soon as possible. Autonomy," said Luo Jun.
Luo Jun said that the key to the development of 3D printing is in application. At present, there are two main factors hindering the development of 3D printing: First, the business model is single, the majority of users must purchase 3D printing equipment to share 3D printing technology, undoubtedly transfer the risk to the user; second, there is a serious shortage of talents.
Based on this, China 3D Printing Technology Industry Alliance established the world's first 3D printing open service platform, 3D printing Whampoa Military Academy, 3D printing online platform in Qingdao, timely release industry dynamics, systematic training industry talents, to ensure that users do not need to purchase equipment, Meet its processing services.
