ERPRO: mastering surface finish with combined post-processing
Surface roughness holds back many end-use applications of 3D-printed parts, and some need more than one finishing step to reach the result they require. AMT partnered with ERPRO 3D Factory to evaluate how well different post-processing combinations reach different levels of surface finish.
