In addition to the fabrication of components with complex designs, LPBF also allows the control of microstructures, such as multiscale internal hierarchical architectures of lattice/cellular arrays and other characteristic structures. For instance, Liu et al. fabricated a gradient heterogeneous structure architecture in additively manufactured 316L stainless steel by integrating LPBF and ultrasonic severe surface rolling to achieve a superior strength-ductility combination.
