Book excerpt: This book focuses on applications of three-dimensional (3D) printing in healthcare. It first describes a range of biomaterials, including their physicochemical and biological properties. It then reviews the current state of the art in bioprinting techniques and the potential application of bioprinting, computer-aided additive manufacturing of cells, tissues, and scaffolds to create organs in regenerative medicine. Further, it discusses the orthopedic applications of 3D printing in the design and fabrication of dental implants, and the use of 3D bioprinting in oral and maxillofacial surgery and in tissue and organ engineering. Lastly, the book examines the 3D printing technologies that are used for the fabrication of the drug delivery system. It also explores the current challenges and the future of 3D bioprinting in medical sciences, as well as the market demand.
