Core Viewpoint - 3D printing technology is becoming a key driver for manufacturing upgrades, particularly in the field of polymer materials for high-strength structural components and precision molds, where China has long relied on imports [1][2]. Group 1: 3D Printing Innovations - A research team led by Professor Ren Xiangkui from Tianjin University has developed a series of low-cost, lightweight, and rapid 3D printing polymer materials and technologies [1]. - The team synthesized a series of efficient "compatibilizers" based on hyperbranched polymers, significantly enhancing the interfacial adhesion of glass and carbon fibers with common engineering plastics [1]. - Newly developed 3D printing materials, including granules and filaments based on polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), polyether ether ketone (PEEK), and polyphenylene sulfide (PPS), exhibit excellent high-temperature resistance, filling a domestic gap in high-end applications [1]. - An innovative "shrinkage-reducing agent" based on block polymers was synthesized, along with optimized 3D printing processes for complex structures, reducing manufacturing cycles from two to three months to just one to three weeks [1]. - The combination of CNC surface polishing technology with fused deposition modeling (FDM) 3D printing significantly improves the surface finish and dimensional accuracy of printed components, expanding the application range in precision parts [1]. Group 2: Halogen-Free Flame Retardants - The research team has successfully developed a series of high-performance halogen-free flame retardants specifically designed for flammable polymers like polypropylene and nylon, maintaining stability at high temperatures of 280°C [2]. - The flame-retardant modified products achieved the highest V0 rating in UL94 combustion tests, producing minimal non-toxic smoke when exposed to fire [2]. - The products meet stringent environmental regulations such as ROHS and REACH, and have demonstrated durability under extreme conditions, maintaining performance after 2000 hours at 85°C and 85% humidity, and after boiling in water at 70°C for 168 hours [2]. - The newly established Polymer Composite Materials Technology Development Center at Tianjin University Zhejiang Research Institute aims to collaborate with enterprises in various fields, including automotive, high-speed rail, home appliances, drones, mold manufacturing, aerospace, and construction [2]. Group 3: Upcoming Events - The 2025 Polymer Industry Annual Conference will be held from September 10-12, 2025, in Hefei, focusing on the theme "The Rise of China's Emerging Industries Leading the Next Decade of Polymers" [5]. - The conference will feature thematic industry forums, innovation exhibitions, and the "New Plastic Award" selection and presentation, providing a platform for the latest macro forecasts, technological achievements, and innovative solutions in the polymer industry [5].
