There are limited publications on the investigation of the tribological properties of CuCrZr alloys produced via the selective laser melting (SLM) method. In this study, it was aimed to optimize the process parameters and examine the effect of process parameters on density, hardness, microstructure, and tribological properties of domestically produced CuCrZr powder to be produced by the SLM method, which allows the production of complex structured parts. The optimum process parameters of the CuCrZr alloy were determined as laser power of 435 W, scanning speed of 350 mm/s, layer thickness of 0.02 mm, laser diameter of 0.1 mm, hatch distance of 0.1 mm, and energy density of 621.42 J/mm3. The relative density, hardness, COF, and wear values of the samples produced with the optimized SLM process parameters were obtained as 99% and 96 HV, 0.5520 ±0.1648, and 1.17x 10-4 (mm3/N.m), respectively.
