Advanced Postprocessing using Chemical Polishing (02/22/2020, Attendees 10)

The surface finishing of the Additive Manufacturing (AM) component can be challenging due to the hidden surfaces. This workshop and video show the University of District of Columbia research applying chemical polishing to improve surface smoothness inside and outside of the complex AM components. This work is also published in the following paper: Tyagi, P.; Goulet, T.; Riso, C.; Garcia-Moreno, F., Reducing Surface Roughness By Chemical Polishing Of Additively Manufactured 3d Printed 316 Stainless Steel Components. The International Journal of Advanced Manufacturing Technology 2019, 100 (9-12), 2895-2900.
