Abstract

Additive manufacturing (AM), also referred to as three-dimensional (3D) printing, has become extremely popular in recent years due to its complex geometrical manufacturing, faster production rate, and its near-net-shape manufacturing. The advantages of AM include the design and printing of diverse parts and materials such as metals, polymers, ceramics, and bioinks, which in turn can be used for the medical and biomedical applications. Traditional manufacturing techniques, such as machining, casting, and molding, have limitations due to complex part generation and high production time; however, AM can build 3D objects directly from a computer-aided design (CAD) model. This CAD model can be designed through design software or extracted directly through reverse engineering processes. 3D printing is a powerful tool to mimic complex human or animal anatomies, building implants, tissue generation, implant-tissue interfaces, dentistry, and so forth. AM technology is rapidly evolving with the advancement in materials, tooling, resolution, computational speed, high accuracy of complex parts, and faster production. The objective of this chapter is to provide the reader with insight into 3D printing for medical applications.
