<p>Additive manufacturing has revolutionized engineering because of its versatility. The most popular type of additive manufacturing is Fused Filament Fabrication, because of its ease of use and low cost. This technology allows component roughness and texturing to be controlled by fuzzy skin feature, introducing irregularities in the nozzle path improving grip and wettability. Currently, knowledge of the fuzzy skin feature is limited, with no papers in the literature studying the impact of parameters on outputs. Therefore, it is necessary to understand how the printing parameters influence and control the fuzzy skin. This study investigates the influence of FFF printing parameters, specifically Layer Thickness (LT), Fuzzy Skin Point Distance (FSPD), and Fuzzy Skin Thickness (FST), on the surface morphology, wettability, and friction coefficient of polylactic acid (PLA) components. Employing a full factorial design and Analysis of Variance (ANOVA), the research explores the effectiveness of the fuzzy skin feature in modifying surface characteristics, giving a strong starting point for future Artificial Intelligence fine tuning and process broadening. The study demonstrates that fuzzy skin effectively reduces the water contact angle, reducing it by more than half compared to the conventional FFF printing. Furthermore, the fuzzy skin feature enhances the coefficient of friction against silicone rubber (simulating hand grip), by up to 84.7% compared to the default printing.</p>
