Özet
Purpose The purpose of this study is the investigation of the friction performance of 3D-printed polylactic acid (PLA) at different infill densities. Design/methodology/approach PLA samples were printed with fused filament fabrication (FFF). Friction performance test of PLA samples were performed under 18 N load at 20 min, 40 min and 60 min using a pin-on-disc tester. Diameter deviation, hardness of 3D-printed PLA, weight variation, coefficient of friction, temperature and wear images were chosen as performance criteria. Findings The hardness values of the samples with 30%, 50% and 70% infill density were determined as 93.9, 99.93 and 102.67 Shore D, respectively. The friction of coefficient values obtained in these samples at 20 min, 40 min and 60 min were measured as 0.5737, 0.4454 and 0.3824, respectively. The least deformation occurred in the sample with 50% occupancy rate and during the test period of 20 min. Practical implications The aim of this study was to determine the best friction performance of 3D-printed biodegradable and biocompatible PLA with different infill densities. Originality/value In the literature, several studies can be found on the mechanical characteristics of 3D-printed parts produced with PLA. However, investigations on the wear characterisation of these parts are very limited. In this regard, the friction coefficient results obtained from different infill density of 3D-printed PLA used in this study will significantly contribute to the literature.
