This study examines how the geometry of surface patterns influences abrasive wear resistance under varying abrasive particle sizes. High-impact polystyrene specimens featuring three different surface conditions—smooth, concave, and convex patterns—were fabricated through 3D printing and subjected to controlled abrasion tests. Aluminum oxide (Al₂O₃) particles ranging from 1.2 to 0.13 mm in size were used as the abrasive medium. Each test employed a total abrasive mass of 6.5 kg over a continuous 3-hour duration to ensure consistent loading and wear progression. Post-test evaluations incorporated mass-loss measurements, optical microscopy, and confocal surface profilometry to characterize wear morphology and quantify changes in roughness. Across all particle sizes, a consistent hierarchy in wear volume was observed: smooth surfaces exhibited the greatest wear, followed by concave patterns, while convex patterns demonstrated the highest resistance. This trend indicates that geometric texturing can effectively modify stress distribution and particle–surface interaction during abrasion. Additionally, larger abrasive particles resulted in increased wear volumes, primarily due to higher normal loading and deeper indentation, aligning well with predictions from Archard’s wear law. These outcomes underscore the substantial role of surface patterning in governing abrasive wear behavior. The findings provide valuable insights for the design of durable components used in heavy machinery, agricultural equipment, and other applications where extended service life under abrasive conditions is essential.
