The analysis of surface roughness of the samples produced by 3D printing

This paper deals with measurement and analysis of surface roughness of samples produced by 3D printing, Gembird white and Verbatim white. Process parameters such as print speed, print layer thickness, and print material changed when the samples were printed. The surface roughness of the samples was measured using the TR200 roughness meter. The paper analyzes the roughness parameter Ra, which represents the mean arithmetic deviation of the profile.
