For this purpose, six samples (30*30*3 mm3) were printed at 0 degrees, 45 degrees, and 90 degrees in x-y and x-z planes with a 100-mu m layer thickness. SPE tests examined erosion at distinct impact angles (30 degrees, 45 degrees, 60 degrees, 90 degrees) and pressures (1, 2, 3 bars). Results showed higher particle velocities reduced erosion resistance, where 45 degrees x-y plane samples demonstrated superior resistance (erosion rates: 0.050, 0.100, 0.220 mg/g under 1, 2, 3 bars, respectively). The 30 degrees impact angle caused maximum erosion, while 90 degrees had the least. Samples positioned horizontally in the x-y plane were most sensitive to impact angles, with 10% higher erosion sensitivity than others. The study highlights how printing direction significantly affects SPE performance in SLS.eninfo:eu-repo/semantics/closedAccessErosion Wear TestPa 3200 GfSelective Laser SinteringSurface AnalysisArticle10.1007/s11665-025-10721-92-s2.0-85217793178
