This study explores beta titanium alloys as advanced biomaterials addressing stress shielding challenges from stiff conventional metallic materials such as Co-Cr, Steels, and Ti-6Al-4V. Using laser powder bed fusion (LPBF) and in situ alloying of Ti and stainless steel powders, we fabricate a novel beta titanium alloy with a BCC phase and refined microstructure. The as-printed alloy exhibits low modulus (~87 GPa) and high strength comparable to commercial Ti-6Al-4V. Notably, the novel alloy demonstrates excellent biocompatibility, showcasing its potential for biomedical implants.
