Efficiently managing multiple process parameters is critical for achieving optimal performance in additive manufacturing. This study investigates the relationship between eight key fused deposition modeling (FDM) and their impact on responses like average surface roughness (Ra), tensile strength (TS), flexural (FS) of carbon fiber-reinforced polyamide 12 (PA 12-CF) material. The integrates response methodology (RSM), grey relational analysis (GRA), wolf optimization (GWO) to achieve this goal. A total 51 experiments were planned using a definitive screening design (DSD) based RSM. printing parameters, including layer thickness, infill density, build orientation, significantly affect Ra, TS, FS. GRA combines into single measure, grade (GRG), regression model developed. GWO then employed optimize GRG across parameters. Comparison with GRA-optimized demonstrates GWO’s ability discover refined solutions, reducing 4.63 μm increasing 88.5 MPa 103.12 MPa, respectively. Practical implications highlight significance industrial settings, where optimized lead reduced costs improved product quality. integrated approach offers systematic optimizing FDM processes, ensuring robustness efficiency manufacturing applications.

Additive manufacturing (AM) techniques make fabricating complex designs, prototypes, and end-user products possible. Conductive polymer composites find applications in flexible electronics, sensor fabrication, electrical circuits. In this study, thermoplastic polyurethane (TPU)-based conductive composite samples were fabricated via fused filament fabrication (FFF). The effects of three important process parameters, including infill density (ID), layer thickness (LT), fan speed (FS), on various mechanical properties (tensile compressive properties) investigated. It was observed that all the considered parameters affect properties, they are significant as per analysis variance (ANOVA). From scanning electron microscopy (SEM) optical microscopy, combinations such low ID, high LT, FS resulted formation defects voids, cracks, warping, which properties. Finally, parameter optimization performed, resulting a with best possible combination at medium FS.
