Additive manufacturing classification is one of the biggest issues faced by AM community. The book provides a comprehensive classification of AM, which can be useful to anyone working in any area of manufacturing. As the classification depends on the interrelation of various AM processes, the book provides concise and critical information of those processes, which can be helpful to anyone looking for a concise book on AM. The book provides original information unavailable in research papers.
