Role of Additive Manufacturing, Augmented Reality, Internet of Things in building Industry 4.0

As the current world is running at great speed, competition among is at an absolute level. The demand for the customized product is increasing in every sector, and this demand will get fulfilled by new types of technologies like Additive Manufacturing (AM), Augmented Reality (AR), Internet of Things (IoT), Big Data Analytics (BDA), Cyber-Physical System (CPSs), Digital Twin, Artificial Intelligence (AI) and Machine Learning (ML), etc. The combination of all these technologies will lead to a sustainable and smart manufacturing system and arises the concept of Industry 4.0 i.e., the Fourth Industrial Revolution. In this paper, we will mainly focus on concepts of Industry 4.0, Additive Manufacturing, Augmented Reality, and Internet of Things. We will also discuss the integration of modern technologies with the help of some case studies.
