Abstract
Additive manufacturing (AM) has revolutionized production techniques. The capability of producing complex internal structures with ease and high accuracy makes this process unique. It has found tremendous applications in several fields of engineering, including biomedical engineering. This chapter is aimed at presenting the latest trend on selected biomedical applications of AM. Particular emphasis was given to orthopedics, bone tissue engineering, dentistry, medical devices, and pharmaceutical applications. Suitable AM processes and materials for various biomedical applications have been presented. Also, the chapter explores the functional requirements of various implants, together with the required mechanical and biological properties. The factors responsible for the dimensional inaccuracies of 3D-printed porous metallic implants and scaffolds are reviewed. Finally, the current limitations and future trends of 4D and 5D printing technologies are highlighted.
