Modification using magnetic field-assisted finishing of the surface roughness and residual stress of additively manufactured components

The choice of the sequence of manufacturing processes is a key aspect of smart manufacturing. It can determine the surface functions of the finished component, and it can revolutionize the way things are made. The focus of this paper is the post-processing-a combination of sanding, polishing, and burnishing-of 316L steel components made using selective laser melting (SLM). The integrity of the surface (including surface defects) is influenced by post-process conditions as well as the sequence of post-processes, which perform functions such as eliminating surface defects generated during SLM, altering the surface roughness, and imparting compressive residual stress.
