3D Printing in Materials Manufacturing Industry: A Realm of Industry 4.0

Additive manufacturing (AM), also known as 3D printing, is a new trend showing promising progress over time in the era of Industry 4.0. So far, various research has been done for increasing reliability and productivity printing process. In this regard, reviewing existing concepts forwarding novel directions are important. This paper reviews summarizes process flow, technologies, configurations, monitoring AM. It started with general AM followed by definitions working principles technologies possible such traditional robot-assisted Then, defect detection, fault diagnosis, open-loop closed-loop control systems discussed. noted that introducing robots into assisting mechanism increases Moreover, integrating machine learning conventional algorithms ensures AM, strategy. Lastly, addresses challenges future trends.
