| Abstract Scope |
Additive manufacturing using Laser Powder Bed Fusion (PBF-LB/M) enables the production of personalised, near-net-shaped implants from materials that are otherwise difficult to handle. It is also a powerful tool for the economical investigation of novel alloy compositions through in-situ alloying of elemental and commercially available powders. Research has shown that in-situ alloying of Ti-6Al-7Nb with copper introduces antibacterial properties, while heat treatment simultaneously improves the mechanical properties. Processing parameters are crucial for producing dense, defect-free parts with good homogeneity in the as-built condition. Furthermore, the findings indicate that the properties of Ti-Al-Nb-Cu alloys can be adjusted to a large extent, suggesting that research into ternary and quaternary titanium alloys containing copper could enable the replacement of costly alloying elements in certain applications. |
