Laser-based Additive Manufacturing (LAM) has been widely used in different industries. However, the quality and repeatability of the components and parts produced by LAM have hindered the spread of this technique. The better understanding of the LAM underlying mechanism can provide insight into acquiring high-quality products. Among researches on underlying physics, there are efforts to study the thermal behavior, as one important part of the complex mechanisms, and its influence on the product quality. This review is presented to comprehensively analyze different approaches to study the thermal behavior. The relationship between thermal behavior and product quality is identified and some recommendations for future research are discussed.
