Copper shows promising characteristics for applications in electrical sliding contacts. In this study, copper reinforced polylactic acid (PLA-copper) composites manufactured by fused deposition modeling (FDM).  Wear behaviour of PLA-copper composites under dry sliding conditions at three different temperature conditions (20oC, 50oC, 70oC) was evaluated by using pin-on-disc wear test equipment with attached heating module with 5N load applied at a sliding velocity of 104.7 mm/s. Tests have presented for 1040 steel bead interacting with polymer composite. Specific wear rates and coefficient of frictions of PLA-Cu polymer composites were evaluated. EDX analysis were conducted to examine the microstructure and scanning electron microscopy is used for the characterization of the worn surfaces.
