This is an ordinary and ordinary day. In the spacious and bright Huaying Hi-Tech 3D Printing Center, a 3D printing device like a neat soldier is working in an orderly manner. At the age of 29, he stood in front of the Huaying Hi-Tech HT251 equipment and focused on operating the machine. The passing workers knew hello to him: "Hey! Hanye!" He smiled back to the other side. As a material research and development engineer, he spends nearly half of his time in the workshop every day, and conducts basic analysis research by repeatedly sintering polymer materials. “There are a lot of things to do, we have to go to the workshop often,†he said.
Last year, the team led by him and the world's largest chemical company BASF jointly developed the new 3D printing material PA-6 powder, the BASF research team sent him a sincere thank you letter, the letter gave him Thanks for your support, suggestions and detailed feedback. The project lasted for one and a half years. From research formula and parameter optimization to communication and cooperation with BASF, all the materials research and development teams are responsible for all aspects, and all aspects are strictly and cautiously improved. Compared with the previously used polyamide-12, the products produced by this innovative material have better strength and thermal stability, and the application and promotion of the results will realize the breakthrough application of 3D printing technology in the direct manufacturing field of automobiles. Young, he also became a half-joking and half-admired "Chen Han" among his colleagues.
It can be said that every aspect of material research and development has been injected with the spirit of craftsman, and his words are the best interpretation of the craftsmanship spirit: "I have become accustomed to the problem of 6 years of trekking on the road of research and development." ——Innovative method——solving the rhythm of the problem's work. In my opinion, 'persistence persistence, optimistic innovation' is the power that drives me forward, and also the 'artisan spirit' in my heart. It is not blindly abiding by tradition. The opposite is true. On the contrary, it is good at using the spirit of innovation, repeatedly researching and optimizing materials, developing the best performance and exerting its greatest value."
6 years of precipitation: concentrating on breaking the monopoly of foreign materials
In recent years, domestic 3D printing technology has been rapidly developed, and its practical application fields are gradually increasing. However, 3D printing materials have become a bottleneck restricting the development of the 3D printing industry. At present, there are few domestic companies capable of producing 3D printed materials, and some of the main materials are imported and the price is high. This has resulted in higher cost of 3D printing products, which has seriously affected the process of industrialization.
In the winter of 2009, Huaying Hi-Tech started hard in a rented 600-square-meter garage in Changsha, Hunan. Dr. Xu Xiaoyu, who has long-term vision, realized that he must have his own material research and development team to break the monopoly of foreign giants and realize the long-term development of the 3D printing industry.
At that time, he was just an intern who had just left the campus. With the incomparable yearning for the 3D printing business, he became a member of the Huaying Hi-Tech material research and development team. On the simple equipment, he started from researching foreign imported materials, to simple milling, monitoring the milling curve, and then to process optimization, keeping improving and working tirelessly. Material research and development is a boring art. It requires great patience and perseverance. It may face setbacks, failures and various risks at any time, but he has not retired. Perseverance is his most touching point. This not only means the innermost determination but the dedication of detail, but also the persistence and resilience of a few years. His insistence is the truest portrayal of the “artisan spirit†of Huaying R&D personnel.
Hard work pays off, after nearly two years of painstaking research, he and his partners have succeeded! In 2011, the FS3200PA, a nylon powder material independently developed by Huasheng Hi-Tech, shocked the world. The material is stable in color and has good oxidation resistance. It can produce high-precision and reproducible parts and can be applied to products with high mechanical properties and toughness. Its successful development has made up for the weak link in the entire LS industry chain, which not only broke the exclusive monopoly of foreign companies on materials, but also greatly reduced the cost, and won a larger market space for LS technology and LS equipment, making Hua Wei Gaoke became the second company in the world to have core material manufacturing technology, the only company in the world that can produce both selective laser sintering (LS) equipment and selective laser sintered (LS) nylon materials.
In 2012, his material research and development team successfully developed the glass microbead composite nylon powder material FS3400GF. In 2013, the mineral fiber composite nylon powder material FS3250MF and the carbon fiber composite nylon powder material FS3400CF were born. According to statistics, his material research and development team successfully developed 14 kinds of 3D printing materials such as polymer materials, composite materials, metals and ceramics during the six years, and has 15 national invention patents.
Touched by their efforts and sweat, they also witnessed the joy of their success. Dr. Xu Xiaoyu said with emotion: "At first I didn't have enough confidence in material research and development, but you didn't let me down. Thank you for being Hua Wei. Great contribution to China's 3D printing business!"
Innovative breakthrough: let polymer materials "play" more patterns
Real craftsmen will never stop pursuing progress in the professional field. In order to meet the needs of customers in different industries, he envisions and works hard to make polymer 3D printing materials "play" more new tricks.
In 2012, BASF Group, the world's largest chemical company, decided to enter the 3D printing industry. After global research, they targeted the fast-growing Huaying Hi-Tech. In 2014, BASF and Huasheng Hi-Tech formally entered into a strategic partnership. The two companies joined forces to invest more than 100 million euros in the development of various special 3D printing materials and equipment for industrial sectors such as automotive parts.
This important task falls on his head, which is both a challenge and an excellent learning opportunity. After receiving more than 30 batches of material samples from BASF, he made a careful and detailed experimental plan, repeated sintering on 3D printing equipment, and observed various data and problems in the sintering process of the recording materials, only 2015 Throughout the year, the sintering experiment was accumulated 173 times, and then the samples printed by each batch of materials were subjected to various experiments such as mechanics and chemistry to observe whether the material was durable and safe during use. After a series of professional performance tests, it is necessary to analyze the various situations that people may encounter when using materials in daily life, so that the research and development of new materials is basically completed.
In his view, although technology research and development are faced with cold numbers, technology itself is to serve people. The spirit of craftsmanship is the discovery and re-solving of small problems in the process of R&D and production, which cannot be sloppy. He said that when researching each new material, it is not a one-step process from start to production. He is always groping, in the constant experiment, each time solve a small problem, each time to improve a small defect, not only to test the best performance of the material, but also to find ways to break through the innovation, this has the PA6 material today Successful listing.
Every time he communicates, communicates and reports with BASF researchers, he has been carefully and rigorously prepared. At the 14 technical exchange conferences in 2015, his logical and rigorous data analysis and meticulous reporting of PPTs have made foreign friends admire them.
From 2009 to 2016, the cold summer came to the seventh spring and autumn, he always adhered to the development of Huaying Hi-Tech, giving the "artisan spirit" a deeper connotation of the times. Strict and meticulous, breakthrough innovation, the attitude of every Huaying people to manufacture products is the persistence and inheritance of Huaxu craftsman spirit. It is this persistence and innovation that has propped up the quality backbone of the industrial-grade 3D printing company Huaying Hi-Tech and created the miracle of the rapid development of Chinese national 3D printing enterprises!
