A state-of-the-art review on implementation of digital twin in additive manufacturing to monitor and control parts quality

Abstract

Both, Additive Manufacturing (AM) and Digital Twin (DT) are emerging technologies. DT is helping AM in process simulation, monitoring and controlling as well as to develop insights on process parameters relation to achieve high parts quality. Therefore, the implementation of DT technology in AM is highly desirable and fruitful. In the current state, DT application on AM has been explored by various researchers for education, manufacturing, maintenance and quality area from the theoretical and practical viewpoints. This paper presents the state-of-the-art literature review on the implementation of DT in AM to monitor and control the parts quality from theoretical and practical viewpoints. Based on the literature, a representation scheme has been extracted to implement DT in AM successfully, and various future research directions are given.
