Abstract
In the study, parts are fused deposition modeling–printed using polylactic acid filaments filled with copper, brass, bronze, tungsten, and carbon fiber. Wear and three-point bending tests are applied to FDM-printed specimens and it is yielded that on-edge oriented specimens had higher flexural strength while flat orientation contributed to wear resistance. Wear tracks are examined, and mostly abrasive wear is detected in the dry sliding condition while adhesive, fatigue and abrasive wear is observed in the wet sliding condition. Brass-filled polylactic acid specimens showed highest flexural strength and flexural modulus with 46.73 MPa and 1.53 GPa, respectively. Besides, the most wear resistant filler is determined as tungsten for dry and wet sliding conditions.
