RESEARCH OF THE RESISTANCE OF POLYCARBONATE SAMPLES MADE BY FDM TECHNOLOGY TO ABRASIVE ACTION

The article deals with the investigation of tribological properties of polycarbonate (PC) material produced by 3D printing using Fused Deposition Modelling (FDM) technology under different layer deposition strategies and their subsequent testing for abrasive wear. The aim of the experiment was to compare the effect of different layer deposition strategies in the FDM process on the abrasive wear of the material at specified process parameters, which were defined according to ASTM G65 standardized tests. Based on these tests, the different strategies were compared and evaluated in terms of their ability to resist abrasive wear, providing insight into the effect of different orientations and layer arrangements on the tribological properties of 3D printed polycarbonate.
