Strategies to enhance Biocompatibility via additive manufacturing for medical applications: A state-of-the-art review

In this review article, various cutting-edge strategies are addressed that aim to enhance the mechanical and functional properties of Biocompatibility metal, which are manufactured using additive manufacturing techniques, in particular for biomedical applications such as implants and prostheses. Additive manufacturing has several advantages, including time saving and cost reduction, especially in small product manufacturing processes and prototypes, freedom of design for complex shapes that are difficult to achieve by traditional methods, the advantage of reducing waste and material waste, the possibility of customizing products to order, enhancing sustainability and reducing environmental impact, and others. It can be said that most of the previous studies focused either on the biological properties of biometallics that were manufactured using addition techniques or improving mechanical properties, while comprehensive strategies that integrate the two aspects together have not been reviewed, and this article shows how to achieve synergistic improvements between the two performances. Any modern integrative revision combines various strategies (alloying, microscopic, surface, computational).
