Abstract: In this paper, the effect of shot blasting parameters such as time, pressure, and grit size were studied over the water contact angle of additively manufactured aluminum alloy (AlSi10Mg) surfaces. The Taguchi L9 orthogonal array was implied to set the correlations and interactions between the shot blasting parameters and water contact angle as output parameters. The analysis of variance establishes a good agreement with the results, revealing the time as the most significant parameter with a 41.98% contribution, followed by the pressure (41.57%) and grit size (16.43%). Further, the roughness measurements and scanning electron microscopy analysis of the shot-blasted surfaces validate the variations in the water contact angle.
