Additive manufacturing (AM) is gaining widespread adoption in the industry due to its capability fabricate intricate and high-performance components. In parallel, increasing emphasis on functional materials AM has highlighted critical need for accurate prediction of mechanical behavior composite systems. This study experimentally investigates tensile strength surface quality carbon fiber-reinforced nylon composites (PA12-CF) fabricated via fused deposition modeling (FDM) models their using artificial neural networks (ANNs). A Taguchi L27 orthogonal array was employed design experiments involving five printing parameters: layer thickness (100, 200, 300 µm), infill pattern (gyroid, honeycomb, triangles), nozzle temperature (250, 270, 290 °C), speed (50, 100, 150 mm/s), density (30, 60, 90%). An analysis variance (ANOVA) revealed that had most significant influence resulting strength, contributing 53.47% variation, with substantially at higher densities. contrast, dominant factor determining roughness, accounting 53.84% thinner layers yielding smoother surfaces. Mechanistically, a enhances internal structural integrity parts, leading an improved load-bearing capacity, while improve interlayer adhesion finish. The highest achieved 69.65 MPa, lowest roughness recorded 9.18 µm. ANN model developed predict both based input parameters. Its performance compared three other machine learning (ML) algorithms: support vector regression (SVR), random forest (RFR), XGBoost. exhibited superior predictive accuracy, coefficient determination (R2 > 0.9912) mean validation error below 0.41% outputs. These findings demonstrate effectiveness ANNs complex relationships between FDM parameters properties highlight potential integrating ML statistical optimize composites.
