At the 19th Industrial Fair, which was officially opened yesterday, the booth 2B008 of the college exhibition area was swayed by the front of the glass cabinets. The various animal shapes and the "Fu" characters were beautiful and the carvings were exquisite. The team led by Professor Zhao Wei from the School of Materials Science and Engineering, Shanghai University of Applied Sciences, is here to showcase the independent innovation of 3D printing of ceramic materials. The largest application area at present is in dental printing. Print teeth, new technology speeds up and increases efficiency Printing teeth is not new. In recent years, 3D printing technology has become more and more developed, and various materials, especially metal and polymer materials, have rapidly developed 3D printing technology and have been widely used in the industrial field. There are many dental applications in the medical field, but previously called 3D. forming. For example, it is applied to the manufacture of metal crowns, bridges, brackets, etc., but compared to metal 3D printing, dental ceramic printing is difficult. The team of Shanghai University of Applied Sciences, Zhao Wei, is the first in China to develop a high-precision industrial grade ceramic material 3D printer based on stereo light curing technology (SLA), and its high-purity alumina, zirconia, silicon nitride and silicon carbide. And printing materials such as gypsum resin. What is the difference between such high-precision 3D printing dental ceramic technology and traditional preparation technology? "3D printing technology is also called additive manufacturing technology. The principle is to decompose the computer-designed 3D model into several layers of planar slices, and then The printed materials are stacked layer by layer and finally stacked into a complete object.†Zhao Wei introduced that before the advent of 3D printing technology, the denture customizer needed to bite the tooth membrane and send it to the factory for repair and engraving. The production cycle was usually longer. 3D printing technology increases efficiency. At the same time, the biggest advantage of ceramic printing is the integrated design and manufacture of complex materials, structures, functions and applications. The product life is twice as long as that of traditional products. Work with healthcare organizations to develop applications "This technology is especially suitable for the all-ceramic denture and jewelry processing industry with high printing precision. At present, we have cooperated with many domestic first-class medical institutions and large denture processing units such as Shanghai Ninth People's Hospital, and the technology has been applied to the unit. Highly recognized.†Zhao Wei introduced that the technology is completely independent innovation and has mastered the core key technologies and equipment with independent intellectual property rights. For example, make a denture, 200 layers of cut surface layer by layer, each layer is only 50 microns thick, thinner than half of the hair. At the same time, due to the mastery of the core technology, its cost will be more grounded. 3D printing ceramic materials, especially the application of this technology direction in dental printing. At present, there are three commercial enterprises in Austria, such as LithoZ in Austria, Admatec in the Netherlands and 3DCERAM in France, which are being developed simultaneously, and the "Chinese method" with completely different underlying technical routes is There are significant advantages in print accuracy, material properties, and material suitability. “At present, our technical cooperation is applying for relevant medical licenses. It is expected that the service will be fully implemented after half a year.†Zhao Wei said that the results of ceramic 3D printing have been smoothly transformed, because the team pays close attention to application in basic research. The goal of the R&D route is to make the final product directly. The future of this technology is not only on one tooth, but its material strength and process precision are expected to play a role in more medical fields, such as hard tissue repair for orthopedics, preparation of large-sized special structural bone components, etc. . Gumeilock established the industry leading through-bolt platform for entrance and sectional sets, providing easy installation. In addition, any of Gumeilock heavy duty levers, trims, turn knobs can be coupled with our Grade 1 mortise locks for ease of ordering. This flexibility creates an answer to a wide array of commercial installations, including hospitality, multi-family, retail, education, healthcare and office spaces. main door lock, main entry lockset, handle lockset, handle door lock, lock in keyed ZHONGSHAN JUYA METAL PRODUCTS CO., LTD , https://www.gumeilock.com
