Abstract Scope |
As the third generation of biomaterials, magnesium (Mg) is a promising candidate for biomedical applications. The traditional manufacturing methods are unable to produce complex geometries required for implants. Advancing manufacturing technologies could open a new window of opportunity for Mg alloys. This study aimed to develop an end-to-end manufacturing solution that enables the fabrication of customized porous Mg implants for craniomaxillofacial applications. Powder-bed inkjet 3D printing method followed by a sintering process was used to fabricate implant-like Mg components with an interconnected porous structure having more than 10 % of overall porosity. Then, clamping fixtures for a three-step machining process together with the adaptive CAM program for tool path planning and collision checking were successfully developed, enabling automated milling of the near-net-shape fabricated Mg implant. Overall, this combination of AM and the automatic post-machining process introduced in the current work will revolutionize the future of Mg alloys for implant applications. |
