There is a big difference between stresses in selective laser melting (SLM) additive manufacturing and cold deformation. Stresses in SLM components are complex residual thermal stresses, most could be relieved due the high temperature of the SLM process that allow dislocation mobility; as a results the SLM components will experience low or minimal plastic deformation. The configurations of residual stresses are complex and could undermine the mechanical properties of the SLM components if an appropriate stress relieving heat treatments are not employed. On the other hand, the uniaxial compressive stresses in cold deformations result in significant plastic deformation that results in high increase in the ultimate tensile strength properties with sharp decrease in ductility due to the much larger dislocation density in the materials.
