Abstract Scope |
Human bones have naturally evolved ways to repair small fractures quickly; however, fractures below the waste require mechanical aids to help bear loading while healing. These techniques are effective but tend to cause a lack of mobility. 3D printed biodegradable metallic implants are now showing promise as an ideal alternative for expediting recovery and increasing mobility, especially with the growth of lattice-based design and better osseointegration techniques.
This study discusses the development and testing of a functional 3D printed implant that integrates such properties, with an eye toward clinical translation. Materials selection and implant design have been done based on printability, load-bearing, biocompatibility, controlled degradation, and osseointegration. An iron-manganese mixture with dopants is used with lattice-based design to minimize material and printed using binder jetting. After fabrication, experiment analysis to evaluate load-bearing, degradation, in-vitro performance, and microstructure has been performed for validation, achieving a functional 3D printed biodegradable metal implant. |
