Additive Manufacturing (AM) technology is obviously advantageous in producing parts with complex structures. However, it is difficult for the as-built surfaces of AM parts to meet the quality requirement, as the as-built surfaces are deteriorated by the inherent characteristics of powder adhesion and balling effect of metal AM technologies, e.g. Selective Laser Melting (SLM). The Abrasive Flow Machining (AFM) is used to polish the outer and inner surfaces of additively manufactured aluminum grille parts, with the abrasive media containing grits of different sizes. The variations of surface topology, material removal and surface roughness of the grille are considered by analyses of measurements of micro-topology and profiles during the AFM process. The experiment results show that clustering of molten metal balls due to the balling effect can be removed effectively from the grille surface, and the surface roughness is reduced from the initial 14 μm to the final 1.8 μm, with pretty good polishing effect being achieved for the outer and inner surfaces of the grille.
