Additive manufacturing of TTFNZ (Ti-4.5Ta-4Fe-7.5Nb-6Zr), a novel metastable β-titanium alloy for advanced engineering applications

The alloy Ti‐6Al‐4V (Ti64; wt%) is extensively used for aerospace and medical applications. However, due to potential drawbacks and societal change, intensive research has been conducted to replace this material for medical use, as such various promising alloy systems have been proposed. By implementing additive manufacturing (AM) in the value chain of load-bearing implants, the question of the printability of these promising medical alloy systems arose as none were explicitly developed for AM.
