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 Koneng 3D Technology focuses on 3D-printed bone implants. Founded in 2016 with a team of about 20 in Hong Kong for R&D and manufacturing, the company completed 50 cases in the first half of this year, expanding its services from Hong Kong to Thailand, Singapore, Kazakhstan, and France. It previously collaborated remotely on a 3D-printed bone replacement for a Kazakh bone cancer patient, who was able to walk one week after surgery and walked normally after a year. Products range from skull to hip implants, with newly launched maxillofacial implants showing rapid growth. The company plans to expand into the mainland China market. ② Manufacturing efficiency: Dongguan Xinhang Plastic has integrated 3D printing with traditional injection molding to create a complementary approach. While traditional mold-making costs RMB 100,000–200,000, the company uses 3D printing to produce an initial run of 50 units for market validation before scaling up production. This has improved overall efficiency by about 20% and reduced costs by about 20%. ③ Supply chain integration: Aolfei High-Tech has provided 3D printing solutions for the jewelry and toy industries since 2005, introduced the UK's AMT nylon post-processing technology to China in 2021, and in 2024 brought in German Toolcraft metal support removal and OTEC automatic polishing technologies. The Hong Kong 3D Printing Association boasts over 80 member companies covering equipment, services, post-processing, and medical applications, deeply integrated into the Greater Bay Area. Value for powder buyers: ① The ramp-up of medical metal implants in the GBA directly drives orders for titanium alloy and cobalt-chromium alloy powders. ② The increasing adoption of automated post-processing, such as metal support removal and automatic polishing, lowers the overall cost of metal 3D printing and expands the application base. ③ The integrated Hong Kong–Shenzhen–Dongguan ecosystem offers new channels for powder supply and validation.
