Influence of a vibrating build platform on the density and hardness of parts made by laser powder bed fusion of metals

•A vibrating build platform influences the properties of PBF-LB/M parts.•At low sample densities, a vibrating build platform has an influence on the density.•At high sample densities, the influence of vibrations on the part density decreases.•The hardness of PBF-LB/M samples increases with a vibrating build platform.
