Improving the surface quality and mechanical properties of selective laser sintered PA2200 components by the vibratory surface finishing process

Abstract This paper attempts to improve the physical and mechanical properties of selective laser sintered polyamide PA2200 components through a vibratory surface finishing process by inducing severe plastic deformation at outer layers. The industrial target additive manufacturing is obtain structures having roughness, hardness, other equivalent or better than those produced conventionally. Compared as-built SLS samples, treated specimens exhibited smooth microstructure more favorable tensile strength. Also, duration showed further improvement in roughness hardness samples. state, surface-treated samples improved almost 90% 15%, respectively. Consequently, microstructural analysis indicates that lower enhanced crucial factor influencing overall strength SLS-PA2200 components. We consider combination VSF processes can successfully handle wide range potential applications. study also highlights efficiency applicability materials. Graphic abstract
