They are currently achieved by post-processing such as grinding of external surfaces which adds extra costs. We derive a dimensionless index to reduce roughness using experimental data and dimensional analysis of causative variables. The hierarchical importance of several variables for surface roughness is uncovered and a high-throughput screening approach provides a pathway for reducing surface roughness without the need for post-processing.
