Polymer surface treatments are now a commonly used technology that finds application across many industries. Additive manufacturing, known as 3D printing, is currently one of the technologies that is used in the production of not only small but also large-size printed parts. Due to the nature and properties of printed parts, one of the necessities is to deal with their surface treatment, which is essential to ensure their durability and functionality. The paper discusses the results of the experimental tests of the mutual adhesion samples basic polymeric materials - filaments such as PLA - polylactic acid, PETG - polyethylene terephthalate glycol and ASA - acrylonitrile styrene acrylate as substrates materials under the coating system produced by FDM 3D printing / Prusa i3 MK3S+/ with two-component coating system LV AKZ 421 /manufacturer Synpo a.s. Pardubice / and which were experimentally evaluated and tested according to ČSN EN ISO 4624 / pull test / and ČSN EN ISO 2409 / cross-cut test / and to ČSN EN ISO 16 276. The best adhesion of the coating system was measured to the surface of the PLA filament.
