Hong Kong Wen Wei Po reports on the accelerating 3D printing application ecosystem in the Greater Bay Area (GBA): ① Medical Metal 3D Printing: Hong Kong-based Ceneng 3D Technology focuses on 3D-printed bone implants. Founded in 2016 with a local R&D and manufacturing team of about 20, the company completed 50 cases in the first half of this year, expanding its reach from Hong Kong to Thailand, Singapore, Kazakhstan, and France. In one notable case, they remotely collaborated on a 3D-printed bone replacement for a Kazakhstani bone cancer patient, who was able to walk within a week after surgery and walked normally after a year. Their product range covers everything from skull caps to hip joints, with newly launched maxillofacial implants growing rapidly. The company plans to expand into the mainland market. ② Manufacturing Efficiency: Dongguan Xinhsing Plastics has integrated 3D printing with traditional injection molding for a complementary approach. While traditional mold-making costs RMB 100,000–200,000, the company uses 3D printing to produce 50 prototypes for market validation before scaling up. This has improved overall efficiency by about 20% and reduced costs by about 20%. ③ Industry Chain Support: Orfei Hi-Tech has provided 3D printing solutions to the jewelry and toy industries since 2005. In 2021, it became the first in China to promote UK-based AMT's nylon post-processing technology, and in 2024 introduced Germany's Toolcraft metal support rapid removal and OTEC automatic polishing technologies. The Hong Kong 3D Printing Association has over 80 corporate members spanning equipment, services, post-processing, and medical applications, deeply integrated into the Greater Bay Area. Value for powder buyers: ① The growing volume of medical metal implants in the GBA directly drives orders for titanium alloy and cobalt-chromium alloy powders. ② The growing adoption of automated post-processing such as metal support removal and automatic polishing lowers the overall cost of metal printing, expanding the application base. ③ The integrated Hong Kong–Shenzhen–Dongguan ecosystem offers new channels for powder supply and validation.
