| Abstract Scope |
Fusion-based additive manufacturing (AM) creates complex, customizable metallic parts, making it ideal for biomedical use. Metal AM techniques such as laser powder bed fusion (LPBF) offer the potential to produce patient-specific implants using beta titanium (β-Ti) alloys, which are valued for their low density, excellent biocompatibility and mechanical strength. However, LPBF introduces unique microstructural features—such as melt pool boundaries, grain orientations, and dislocation networks—resulting from rapid solidification under steep thermal gradients. These characteristics impart a hierarchical structure that differs significantly from conventionally manufactured materials.
In this work, we compare β-Ti alloys fabricated via LPBF with those produced through traditional arc melting to understand the influence of processing on microstructure and bio-mechanical properties. Detailed microstructural characterization is conducted to trace the thermal history and solidification dynamics unique to AM. We then correlate these findings with bio-mechanical behavior. These findings advance insights into AM Ti alloys for biomedical applications. |
