Chemical polishing of Internal and External Surfaces of AM Stainless Steel Parts

The surface finishing of the Additive Manufacturing (AM) component can be challenging due to the hidden surfaces. This video shows the University of District of Columbia research applying chemical polishing to improve surface smoothness inside and outside of the complex AM components.
