Abstract Although numerous reports have elucidated the neurotoxic impacts of Ti-6Al-4V (Ti64) due to the presence of vanadium, it is the most widely used biomedical Ti material. This is because it exhibits significantly better mechanical performance characteristics than those of pure Ti. In addition to the possibility of facilitating the production of customized medicines, selective laser melting (SLM) additive manufacturing (AM) can enable pure Ti to match the properties of Ti64 by utilizing several mechanisms such as grain refinement and solid solution strengthening. These results can be obtained due to the high cooling rate of the AM process and via a possible modification in the alloy chemistry of Ti. Herein, we report a novel approach that endows the pure Ti prepared via AM with excellent mechanical properties (ultimate tensile strength, yield strength, elongation, and microhardness of 1057.05 MPa, 784.59 MPa, 24.09%, and 307 Hv, respectively), corrosion resistance, and biocompatibility, while significantly reducing the cost of the powder. The pure Ti material developed in this study has significant potential for use as an advanced biomedical material in a variety of applications such as dental and bone structure replacement. Furthermore, it can act as a low-cost alternative to biomedical materials such as Ti-6Al-4V.

具有优异机械性能、低成本和生物相容性的纯钛增材制造，可替代 Ti-6Al-4 V

摘要 尽管大量报道阐明了 Ti-6Al-4V (Ti64) 由于钒的存在对神经毒性的影响，但它是应用最广泛的生物医学钛材料。这是因为它表现出比纯钛明显更好的机械性能特性。除了促进定制药物生产的可能性外，选择性激光熔化 (SLM) 增材制造 (AM) 还可以利用晶粒细化和固溶强化等多种机制，使纯钛与 Ti64 的特性相匹配。由于增材制造工艺的高冷却速率和钛合金化学性质的可能修改，可以获得这些结果。在此，我们报告了一种新方法，使通过 AM 制备的纯钛具有优异的机械性能（极限拉伸强度，屈服强度、伸长率和显微硬度分别为 1057.05 MPa、784.59 MPa、24.09% 和 307 Hv）、耐腐蚀性和生物相容性，同时显着降低粉末成本。本研究中开发的纯钛材料在牙科和骨骼结构置换等各种应用中作为先进的生物医学材料具有巨大的潜力。此外，它可以作为 Ti-6Al-4V 等生物医学材料的低成本替代品。本研究中开发的纯钛材料在牙科和骨骼结构置换等各种应用中作为先进的生物医学材料具有巨大的潜力。此外，它可以作为 Ti-6Al-4V 等生物医学材料的低成本替代品。本研究中开发的纯钛材料在牙科和骨骼结构置换等各种应用中作为先进的生物医学材料具有巨大的潜力。此外，它可以作为 Ti-6Al-4V 等生物医学材料的低成本替代品。
