Abstract
Industrial automation in the realm of industry 4.0 is on the rise since 21st century. Industry 4.0 makesafactory smart by incorporating automation and using cyber physical systems, internet of things, high speed computing and automated manufacturing systems. The execution stage of an automated production industry is smart manufacturing which exists in the form of an additive manufacturing system. The importance of additive manufacturing is more pronounced in automotive and aerospace industries due to their high rate of production. This review paper highlights the importance of integrating additive manufacturing systems with industry 4.0. A proposed model of smart manufacturing is also presented in which artificial intelligence is incorporated in additive manufacturing systems for improving the overall efficacy of production industries.
