Additive Manufacturing (AM) is a novel field that has revolutionary advantages when compared with traditional reductive manufacturing processes, specifically in terms of safety in the workplace. The more AM technologies are integrated into manufacturing and industrial applications; the greater the value of understanding the safety implications will be. Research indicates that AM reduces mechanical, chemical, thermal and physical risks, which reduces the occurrence of injuries. AM control systems are largely digitized, reducing the probability of human error and reducing material waste. This paper examines the role of AM in reducing manufacturing hazards while comparing it with traditional manufacturing practices, while reviewing case studies, limitations and the future of manufacturing with AM and its adoption in Industry 4.0.
