Roughness data of internal and external surfaces produced through EBM technique

This dataset is referred to the paper "Surface roughness model for Electron Beam Melting (EBM) processing Ti6Al4V" by Galati M., Rizza G., Delfanti S. and Denti L. It contains an STL file with the geometry of the artefact and an Excel file with all the roughness data collected. The artefact is produced through an EBM machine. Roughness data were collected through a profilometer and a confocal profilometer for internal and external surfaces. All the collected data are reported in the Excel file. These roughness data are adopted to develop the regression models capable to to describe upskin and downskin surfaces.
