20.500.12556/RUL-127568 Effect of sanding and plasma treatment of 3D-printed parts on bonding to wood with PVAc adhesive Additive manufacturing is becoming increasingly important for manufacturing end products, not just prototyping. However, the size of 3D-printed products is limited due to available printer sizes and other technological limitations. For example, making furniture from 3D-printed parts and wooden elements requires adequate adhesive joints. Since materials for 3D printing usually do not bond very well with adhesives designed for woodworking, they require special surface preparation to improve adhesion. In this study, fused deposition modelling (FDM) 3D-printed parts made of polylactic acid (PLA), polylactic acid with wood flour additive (Wood-PLA), and acrylonitrile-butadiene-styrene (ABS) polymers were bonded to wood with polyvinyl acetate (PVAc) adhesive. The surfaces of the samples were bonded as either non-treated, sanded, plasma treated, or sanded and plasma treated to evaluate the effect of each surface preparation on the bondability of the 3D-printed surfaces. Different surface preparations affected the bond shear strength in different ways. The plasma treatment significantly reduced water contact angles on all tested printing materials and increased the bond tensile shear strength of the adhesive used. The increase in bond strength was highest for the surfaces that had been both sanded and plasma treated. The highest increase was found for the ABS material (untreated 0.05 MPa; sanded and plasma treated 4.83 MPa) followed by Wood-PLA (from 0.45 MPa to 3.96 MPa) and PLA (from 0.55 MPa to 3.72 MPa). Analysis with a scanning electron microscope showed the smooth surfaces of the 3D-printed parts, which became rougher with sanding with more protruded particles, but plasma treatment partially melted the surface structures on the thermoplastic polymer surfaces. 3D printing adhesive bonding plasma treatment beech wood PLA ABS 3D tiskanje lepljenje obdelava s plazmo bukovina PLA ABS true false true Angleški jezik Slovenski jezik Članek v reviji 2021-06-15 11:57:34 2021-06-15 11:57:41 2022-09-06 03:52:01 0000-00-00 00:00:00 2021 0 0 16 str. iss. 8, art. 1211 Vol. 13 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*83 2073-4360 10.3390/polym13081211 58968835 RAZ_Kariz_Mirko_2021.pdf RAZ_Kariz_Mirko_2021.pdf 1 F07D8E02BE24BA948400A9C24669B313 42c45fe02d6cfda5271e4c7d946bb5be5a6b9343df71d73614f57923e2e6ff60 411ce0f7-a045-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154435 https://www.mdpi.com/2073-4360/13/8/1211 1 075ffa11-cdc0-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143997 Biotehniška fakulteta 0 0 0
