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.
