ABSTRACT
Additive manufacturing (AM) is a relatively modern development in manufacturing and has become a mainstream process in around 40 years of its development. Its key advantages include freedom of design, mass customization, waste minimization, and the ability to produce complex structures and quick prototyping, making it a preferred choice. AM material requirement considers the ability to produce feedstock in an appropriate form in accordance with the AM process, its suitable processing and the ease of post-processing to improve geometry and properties. Consequently, material selection plays an inevitable role in AM as the market witnesses the regular emergence of radically new materials. This chapter attempts to review some commonly used AM methods, namely, fused deposition modelling (FDM), selective laser sintering (SLS) and stereolithography (SLA), as well as the materials used therein. The materials considered fall under metals, ceramics and polymers. Further, the applications of AM materials and their future scope have been discussed.
