This study delves into selective laser melting (SLM). By using M300 steel in virgin and recycled powder form (after 20 cycles), with the aim of reducing cost printing for practical application maraging steel, a comprehensive comparison between two types was evaluated. The powder’s morphology analyzed scanning electron microscopy (SEM) backscattered electrons (BSE). particles were seen to have spherical shape, notable number satellites attached their surfaces. particle size distribution (PSD) examined ranged from 10 90 µm both powders. In addition, porosity exhibited an average value 0.07% 0.10% powder. microstructure examined. Additionally, surface wettability tested, it display wetting behavior powder, while blackened surfaces showed higher angle than untreated (hydrophobic). 2D roughness measurements that had no significant difference (Ra = 5.33 µm, Rz 24.17 µm) before blackening 5.48 24.07 after blackening. Corrosion tests proved did not affect corrosion properties material, caused partial samples, regardless used
