On May 14, 2024, Aide Technology, through its subsidiary Aide Investment, jointly established Yikexing with Deyiwei and Zhiwei Structures, entering the R&D and industrialization of (BJ) 3D printing technology in the medical device field. The entity is controlled by Deyiwei with Aide Technology as a minority shareholder; it is positioned as an upstream raw material layout and extension, currently in the product R&D stage with no revenue yet. Yikexing's main business centers on (BJ) 3D printing as its core process, providing complete customized solutions for small-batch, rapid production of metal device components, with a focus on refined solutions such as surgical tools. Aide Technology has bound its R&D staff Cheng Hongyuan and Wu Jian, along with external consultant Wang Yingjing, to the project's interests through Zhiwei Structures. In 2024, Aide Technology purchased key components for artificial joint surgical tools from Deyiwei for RMB 52,300, used for sample trial production and technical feasibility validation. This layout advances metal additive manufacturing from the equipment and powder end toward finished medical devices; small-batch rapid customization of surgical tools places more direct demands on powder batch consistency and process stability. Yikexing has stated it will also serve other medical device manufacturers, meaning its powder and process needs are expected to spill over into a broader supply chain. Value for powder buyers: (1) Monitor small-batch customization demand for metal powders used in surgical tools and engage early with process-focused companies like Yikexing; (2) Use trial production of key artificial joint surgical tool components as an entry point to validate powder forming quality in medical scenarios; (3) Watch the related-party transaction channel between Deyiwei and Aide Technology, as its sample trial production procurement may serve as a leading indicator for introducing powder categories.
