Surface treatment methods
In this work package, the analysis of surface characteristics for ABS-M30 parts will be conducted with the aim of improving the decorative surface properties. In general, FDM-parts show rough and wavy surfaces with stair-stepping effects whenever the parts have sloped or rounded geometries. Important FDM process related parameters for the surface characteristics include: layer thickness, filament width, air gap and build orientation of the component. The post treatment will be focused on mechanical methods such as vibratory grinding and abrasive blasting. For mass finishing, the process parameters granulate, geometry of the granulate, finishing time, and intensity will be analyzed. The influence of layer thickness, build orientation, and measurement direction on the surface roughness of untreated parts is shown in Figure 2.
