Surface Roughness Investigation of Poly-Jet 3D Printing - MDPI

Surface roughness, often shortened to roughness, is a component of surface finish (surface texture). It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. In surface metrology, roughness is typically considered to be the high-frequency, short-… WebThis high-quality model is game-ready, low poly, and highly detailed, making it perfect for use in games, movies, animations, or as a base mesh for customization.
