Tehnologije 3D tiska postajajo iz dneva v dan bolj dostopne vsakemu izmed nas. Močno se širi tudi sama izbira materialov namenjenih 3D tiskanju. Skozi zadnja leta vedno večji pomen pridobivajo okolju prijazni materiali, v katere sodijo tudi lesno-plastični kompoziti. V naši nalogi smo proučili, kako se 3D tiskani deli iz lesno-plastičnega kompozita, PLA in ABS odzivajo na površinsko obdelavo. Tekom eksperimenta smo določili nekaj osnovnih značilnosti premaznih sredstev in izmerili stične kote treh testnih tekočin na 3D tiskani površini, na podlagi katerih smo izračunali prosto površinsko energijo. Ugotovili smo, da z brušenjem izboljšujemo vodoodbojne lastnosti vseh materialov in znižamo hrapavost površine. Oprijem premazov je bil najboljši na podlagi iz lesno-plastičnega kompozita. Prišli smo do zaključka, da lahko vse uporabljene materiale površinsko obdelamo in s tem dosežemo željen končni videz površin (sijaj, barva) ter želeno gladkost.

• Title: Surface treatment of 3D printed parts made of wood-plastic composites

Abstract

3D printing technologies are becoming more accessible, and the choice of the materials used for 3D printing is also expanding greatly. In recent years, environmentally friendly materials, such as wood-plastic composites, are becoming increasingly important. In our thesis, we studied how 3D-printed parts made of wood-plastic composite, PLA and ABS materials respond to surface treatment. During the experiment, we determined some basic coating characteristics and measured the contact angles of three test fluids on a 3D printed surface, on the basis of which we then calculated the surface free energy. We found that sanding improved the water-repellent properties of all materials and reduced the surface roughness. The adhesion of coatings was best on a wood-plastic composite substrate. We conclude that all the used materials can be surface treated and thus achieve the desired final appearance of the surface (gloss, colour) as well as the desired roughness.
