Additive manufacturing enables the manufacturing of parts with complex geometries that are not easy to be manufactured by conventional methods such as machining or forging. Despite their numerous advantages, additive manufacturing methods have some drawbacks, such as poor surface quality as a primary concern. Parts with high surface roughness tend to show poor fatigue resistance; thus, they cannot be reliable under dynamic load conditions. Therefore, additively manufactured parts should be subjected to additional surface finish operations to improve surface quality and eliminate the negative effects of surface roughness. In this review, one of the most popular methods among modern surface finish processes, known as laser polishing, has been discussed. Process parameters, changes in processed part morphology, and applications along with the advantages and limitations of the method have also been explained to have a good understanding of the importance of this promising method.
