Laser powder bed fusion (LPBF) offers significant advantages for printing Cu–Cr–Zr alloy, such as thermal stability, design flexibility, and impressive strength. However, surface defects pore formation, often caused by using unoptimized parameters, can impact the efficiency of complex geometries parts. The primary goal this research is to minimize these optimizing key processing parameters. In research, laser spot size (100, 200, 300 µm), scan speed (450, 650, 850 mm/s) layer thickness (30, 60, 90 µm) were examined achieve a defect-free copper alloy part. Nanohardness, porosity roughness considered response variables. Analysis variance (ANOVA) coupled with proportional assessment (COPRAS) approach was performed identify optimal parameter settings. While adopting settings, there 69.9% reduction in roughness, 98.5% 91.9% nanohardness printed Cu Additionally, effects different combinations input parameters on mechanism that lies behind formation demonstrated. implementation 100 µm diameter, 30 650 mm/s resulted parts reduced 0.13%, minimum 10.37 µm, maximum 6.2 GPa, according confirmation experiments conducted ideal initial Moreover, obtained result from has greater concurrence COPRAS approach.
