ASA (Acrylonitrile Styrene Acrylate) filament is widely used in outdoor applications thanks to its superior properties.It is exposed to wear due to the environments in which it is used.In this study, the tribological properties of the samples produced at different infill densities (30%, 60%, and 90%) were investigated.Samples were produced using the fused filament fabrication method prior to experiments.Friction tests were carried out on a pin-on disc test device.The friction coefficient, wear rates, hardness, and diameter values of the samples were measured.According to the results obtained, it was understood that there was little change in the tribological properties of the samples according to the infill densities.In addition, 90% infill density samples present higher hardness values and lower wear rates compared to other samples.The study also shows that the fused filament fabrication method is a suitable technique to produce samples from the strong ASA polymer.
