Abstract Scope |
Low-cost metal-polymer filaments are being widely used in material extrusion printers to manufacture parts for a wide range of applications in the automotive and biomedical industries. These filaments can be used to produce parts with intricate details and complex internal geometries. Parts printed with such filaments have rough surfaces with a poor surface finish after the de-binding and sintering process. The high surface roughness affects aesthetics, corrosion behavior, and mechanical properties. Traditional finishing techniques such as sandblasting are limited to the external surfaces, and it is a challenge to polish the internal surfaces of these printed parts. Electropolishing offers an alternate method to reduce the surface roughness of both external and internal surfaces. We present a parametric study of electropolishing parts printed using the copper filament material extrusion process. The influence of current density, deposition time, and other electrochemical process parameters on the surface finish will be presented. |
