The book explains the fundamentals, the theoretical development, the selection of techniques and equipment, laser additive technologies, and the use of selective laser melting. The significant applications in a wide range of sectors include medicine, aerospace, defence, the automotive industry, construction field, jewellery, and rapid tooling. Its purpose is to disseminate knowledge about developing and designing products for aerospace application. The experimental and additive simulation for mechanical behaviour is provided in this thesis. It is intended for researches postgraduate, and undergraduate students of additive manufacturing, mechanical engineering, and production engineering stream.
