Three-dimensional (3D) printing is a manufacturing process in which a physical three-dimensional part is created from a digital design. The process of 3D printing comprises of laying down thin layers of material in the form of cement or metal, powdered or liquid plastic, which are then joined together to create a desired part or object. Lately, 3D printing has emerged as a powerful tool for revolutionizing the pharmaceutical sector. There are several potential applications of 3D printing that range from dosage form design and pre-clinical drug development to the fabrication of regenerative medicine and medical implant devices. In the clinical practice, technologies like 3D printing can prove to be extremely helpful in personalizing the medicines. This book is a compilation of chapters that discuss the most vital concepts and emerging trends of 3D printing in the field of pharmaceuticals. A number of latest researches have been included to keep the readers up-to-date with the global concepts in this area of study. The extensive content of this book provides the students and professionals associated with the development of pharmaceuticals with a thorough understanding of the subject.
