 Additive manufacturing, AM, has become increasingly popular due to its ability to produce complex geometrical shapes directly from CAD designs. Despite its advantages over traditional fabrication methods, AM parts are often plagued by anisotropic properties which can lead to poor workability and the need for tooling. Post-processing treatments have been developed to address these issues and improve the microstructure and functionality of AM parts. This paper reviews different post-processing techniques used on AM parts and demonstrates how they can be used to increase mechanical characteristics such as stress state, bending stress, impact strength, hardness, fatigue, and other physical characteristics like crystallinity, viscosity, processability, dynamic stability, reactivity, heat deflection temperature, and microstructural structure.
