Abstract: According to an example, a recoater for a three-dimensional (3D) printer may include a cylindrical element having a surface to spread build material particles. The build material particles may have a specified average dimension and the surface may include a plurality of depressions that have dimensions that are smaller than the specified average dimension of the build material particles.
