Opis:
3D printing in FDM (Fused Deposition Modelling) technology is commonly used, mainly in the preparation of prototypes, but also for the production of ready-made elements. Objects printed using the FDM method have characteristic, adverse surface features related to the limitations of this technology. That is why surface treatment of 3D prints becomes crucial. One of the method is metal plating of elements. The most frequently used material in FDM technology is PLA (polylactic acid) and ABS (acrylonitrile butadiene styrene). Study of surface parameters determination for ABS prints after galvanic copper plating is presented in this paper. For this purpose, samples printed with ABS were smoothed in acetone vapour. Most favorable parameters of the surface were obtained for samples that had contact with acetone vapour for 60 minutes. Ultimately, surface analysis of samples after graphite coating and subjected to copper plating was performed. It was found that surface parameters are close to results obtained with traditional methods of metal processing.

Opis:
Electropolishing is electrochemical method used in metal working that has a vital role in production of medical apparatus, in food or electric industry. The purpose of this paper is to determine optimal current parameters and time required for conducting electropolishing process from the perspective of changes of surface microgeometry. Furthermore, effect of different types of mechanical working used before electropolishing on final surface state was evaluated by observation in changes of topography. Research was conducted on electrolytic copper and brass. Analysis of surface geometry and its parameters (Ra, Sa) was used as criterion describing efficiency of chemical electropolishing. Results of the experiment allow for current parameter optimization of electrochemical polishing process for selected non-ferrous alloys with preliminary mechanical preparation of the surface.
