ABSTRACT
Additive manufacturing will be able to create complex net-shaped materials in appropriate components after further research and development. New developments in the four most prevalent additive manufacturing processes for metallic materials—powder bed fusion, direct energy deposition, binder jetting, and sheet lamination—will be reviewed. Metals, ceramics, and composites are only few of the materials that fit this description. For AM procedures, polymers and metals are commercially accessible, whereas ceramics and composites are still in the research and development stage. In this chapter, we take a look at the fundamentals of designing composite materials and alloys for AM. Most AM composites consist of a matrix material such as polymer, ceramic, metal, or fibre reinforcement. Functionally Graded Materials (FGMs) are seen as a successful use of AM due to the fact that their characteristics may be optimized throughout the manufacturing process. Since the nose cone of a missile must withstand very high temperatures, it is constructed using AM technology. The ceramic is graded to refractory metal on the exterior. This study will examine the practical relevance of AM for various composites, the procedures involved, the outcomes produced, and the obstacles that must be overcome in order to realize its full potential. AM-made parts will be compared and assessed based on their process principles, microstructures, and mechanical properties. At last, some recommendations for further study will be offered.
