There has been a great deal of progress in additive manufacturing (AM) during the past two decades and recent developments have been highlighted by many researchers. However, until now, there has been a limit to what is available for beginners in a step-by-step format, showcasing the different commercial AM technologies for field application. This book helps fill that gap. Additive Manufacturing: Applications and Innovations presents case studies of commonly used AM technologies with basic numerical problems for better understanding. It also includes hybrid processes and 4D printing applications, which currently are not offered in other AM books.
