Walther Trowal developed the “AM post process machines”, model range AM, especially for refining the surface of components produced with additive manufacturing. The experience of the first customers using these machines shows that the mass finishing technology creates surface finishes in one single step, which meet the highest demands.
Most 3D printed components are produced by placing material layers on top of each other, creating a “staircasing” effect on their surface with, generally, a very high initial surface roughness. For this reason, many of these components must undergo a surface smoothing or polishing operation.
