Abstract

A significant barrier to the broad adoption of Additive Manufacturing is the lack of quality and repeatability on the manufactured part. A promising approach to overcome this limitation is process monitoring and real-time process control. This paper provides an overview of current works related to the in-situ monitoring of the properties related to material (e.g. geometry, surface, or thermal property) in AM processes using optical sensors. The research contents of these works, such as the parameter under monitoring and the types of sensors, are categorized and summarized. Based on the review, an outlook of future works is presented.
