Role of additive manufacturing and various reinforcements in MMCs related to biomedical applications

ABSTRACT

In the current scenario, Additive manufacturing has many applications and is of interest in the biomedical field. The characteristics of parts manufactured by additive manufacturing continue to improve, which is contributing to their increasing usage in medical implants. Additive manufacturing had offered certain advantages in medical implants including medical outcomes, reduced operating time, and cost-effectiveness, as well as adjusting and integrating stents. Along with various advantages, the various types of additive manufacturing techniques like direct metal laser sintering, stereolithography, selective laser sintering, electron beam melting, and selective laser melting are discussed. Other than Additive Manufacturing, Reinforcement played an important role in influencing the mechanical characteristics of MMCs. The types and amount of reinforcement are crucial in maintaining biocompatibility, bio-activeness, non-toxicity, and reduction in porosity. This article reviews the literature on additive manufacturing techniques and their types, highlighting certain applications, and analysing the reinforcement role in MMCs in order to influence the mechanical properties of the composite. The ability to produce biocompatible materials, create customised implants, and add a porous scaffold surface, are the advantages that have the biggest impact on the biomedical sector.
