Abstract
This review presents the transformative potential of powder bed fusion (PBF) in manufacturing orthopedic implants, with a particular focus on β-Ti-Nb-based ternary and quaternary titanium alloys. These alloys, such as Ti–18Zr–14Nb, Ti–29Nb–13Ta–4.6Zr, and Ti–35Nb–7Zr–5Ta (TNZT), offer significant advantages over conventional materials like Co–Cr alloys and Ti–6Al–4V due to their lower Young's modulus, excellent biocompatibility, and reduced stress shielding effects. The review covers the period from 2015 to September 2024 and highlights advancements in PBF-fabricated β-Ti alloys, emphasizing their potential to improve implant longevity and patient outcomes by minimizing the risks of implant failure associated with conventional materials.
本文综述了粉末床熔融（PBF）在制造骨科植入物方面的变革潜力，特别关注β- ti - nb基三元和四元钛合金。这些合金，如Ti-18Zr-14Nb、Ti-29Nb-13Ta-4.6Zr和Ti-35Nb-7Zr-5Ta (TNZT)，由于其较低的杨氏模量、优异的生物相容性和较低的应力屏蔽效应，与Co-Cr合金和Ti-6Al-4V等传统材料相比，具有显著的优势。该综述涵盖了2015年至2024年9月期间，重点介绍了pbf制造β-钛合金的进展，强调了它们通过最大限度地降低与传统材料相关的种植体失败风险来提高种植体寿命和患者预后的潜力。
