Although additive manufacturing (AM), also known as 3D printing, has been around for almost 40 years, few people know how it actually works and the huge impact and benefits it offers. This book explains what AM is, using business theories to explain and illustrate why AM is increasingly being used across industries. The book translates complex engineering technology into relevant managerial terminology, using real-world examples from industries such as apparel, construction and transportation. It provides an introduction into the technical background of AM before expanding on the applications, opportunities and challenges to business models. Offering a unique managerial perspective, this book is aimed primarily at a scholarly audience and those researching across business disciplines, including technology management, manufacturing, production and operations management. It can also be used in emerging business courses on AM.
