Researchers at Monash University have developed a novel method to electropolish the internal surfaces of 3D-printed metal components, addressing the challenge of surface roughness in complex geometries. By co-printing a porous, low-density internal electrode made of the same metal, the process ensures conformity to intricate internal surfaces, enabling effective and homogenous electropolishing. The method reduces internal surface roughness by 85% in just five minutes and improves electrochemical properties such as pitting resistance. The electrode is designed to be mechanically weaker than the main component, allowing easy removal without residue. This innovation enhances the performance and reliability of 3D-printed metal components across various industries.
