In recent years, with the maturity and popularity of SLA 3D printing technology, more and more industries and customers are adopting this technology, from handboard to shoe mold, from tooth mold to sculpture, from automobile to architecture. With the expansion and deepening of industrial applications, the performance of materials is increasingly affecting the development trend of 3D printing, and the reliability and cost of materials are also receiving more and more attention.
The research and development of materials is an important force to promote the transformation and development of traditional manufacturing to digital manufacturing, as a well-known 3D printing integrated solution provider in China, Westerstein has specially set up a postdoctoral 3D printing materials research laboratory, for the industrial field for the application needs of parts design optimization to continue to carry out material innovation, the additive manufacturing technology to industrial production-level applications, the R & D team is a high-level research team led by Canadian polymer materials postdoctoral fellows with overseas study background and rich industrial research and development experience. All are engineers with rich experience in the field of photosensitive resin materials, with the international leading level, and have established a perfect integrated production and marketing model of R&D, production and sales of 3D printing materials, and realized the strict quality assurance of 3D printing materials from research and development to production. In addition, Westan has maintained long-term industry-university-research cooperation with many well-known universities at home and abroad, such as Tsinghua Strait Research Institute, realizing the seamless connection of scientific research, experimental development and market promotion, and promoting the development of the mainland 3D printing industry. The establishment of the postdoctoral 3D printing materials research laboratory also laid the foundation for Westan to establish a municipal provincial technology center and a national technology center.

Laboratory personnel are working on new photosensitive resin materials
The materials R&D team, led by Dr. Weng, is constantly developing new materials in the field of 3D printing materials, constantly pushing the limits of performance to cope with a wider range of production applications. R & D department almost every day soaked in the laboratory, carried out thousands of tests, in order to find the best performance of the diluent dosage, R & D personnel overturned nearly a hundred formulas, in order to achieve or better than the standard tolerance of injection molded plastics, repeated test proofing, with different layer thickness, different machines to play nearly a thousand samples, and then through the mechanical properties test, comprehensive surface quality and mechanical properties for adjustment and optimization, they will do key test data statistics for each material, including toughness, strength, hardness, details, odor, The ease of cleaning makes it easier for customers to choose the ideal material that suits their requirements.

After more than three years of efforts, in the continuous test, Westerstein's material research and development team has developed a series of excellent performance, safe and reliable, complete types of 3D printing materials, including high toughness, high strength, transparency, high temperature resistant materials, etc. The lineup of 3D printing materials continues to expand, the variety is more and more abundant, covering resins, powders, etc., providing a richer choice of materials for industrial users to use 3D printing technology for product development and innovation. Compared with the "secondary research and development" based on the modification of foreign materials, Westan's materials belong to the real "first-hand research and development", and the product quality and stability can withstand the market test.

Independent research and development, production and sales of photosensitive resin materials, in their own printer base services and testing faster update iteration, so that the printing effect performance is more outstanding.

△ 3D printing detail display, fast curing speed, both precision and delicacy, its detail expression is also quite amazing.
In addition to the pursuit of excellence in performance, the sense of experience in the post-processing process is also the focus of Westerstein.com. At present, most of the post-processing is still manual cleaning, the labor cost required is relatively high, if the material is difficult to clean, it is bound to increase the time and difficulty of post-processing, and the texture and surface quality of the sample will be greatly reduced. Westerstein worries about customers, improving the mechanical properties of materials while taking into account the need for easy cleaning:
Low viscosity, easy to clean non-stick hands, saving a lot of trouble for post-processing. The master of post-treatment said that it is better to clean and polish than the general white material, and more samples can be washed at the same time, saving time and effort and saving alcohol.
Superior mechanical properties and easy to clean features, so that more and more prototype printers and factories choose it. The quality of the sample is the most important, and the material determines the quality of the sample.
△ Physical properties of 3D printing materials
Weistan Chairman Wu Guobao said: "In recent years, Weistan has worked with partners to discuss the application of photosensitive resins in the 3D printing industry, introducing a number of innovative solutions covering industries such as automotive, consumer goods, medical, industrial and architectural models. Through these explorations, we hope to open up the application market of photosensitive resin in the 3D printing industry and meet the needs of more industrial-grade applications. On the road of 3D printing material research and development, we will continue to improve performance, continue to reduce costs, continue to make breakthroughs, continue to enrich the variety of materials, maintain the advanced level of the industry, and continue to provide 3D printing service providers with a variety of high-performance, cost-effective high-quality resins. Of course, in addition to photosensitive resin materials, nylon plus glass fiber, nylon + carbon fiber and various metal powder materials, we are also in continuous research and development, we will continue to develop more high-quality and inexpensive 3D printing materials, to promote the development of 3D technology to contribute. ”
