Thermal Post-Processing Techniques for Additive Manufacturing

Additive manufacturing (AM) has revolutionized many industries. AM methods can produce intricate geometries, require virtually no tooling, and reduce production times. However, challenges include poor surface finish, undesired microstructural phases, defects, warping, internal pores, decreased corrosion resistance, lower mechanical properties, and durability. These issues avert additive manufactured components from in-service applications. Thermal post-processes, such as laser shock peening and polishing, hot-isostatic pressing, and annealing, are commonly applied to address these challenges. These methods have demonstrated their capacity to improve mechanical properties. Various thermal post-processes methods and their associated outcomes will be compiled in this study. Thermal post-processes and their impact on additively built parts will be discussed. This chapter will provide a comprehensive analysis of the thermal post-process strategies used to improve the thermophysical characteristics of the manufactured components.
