Testing was conducted on composite containing 30% walnut shell fibers, with Ultimate Tensile Strength (UTS) Elastic Modulus (E) measured as per ASTM D638 standards. Experimental factors included Layer Thickness (LT), Nozzle Temperature (NT), Deposition Angle (DA), Printing Speed (PS). Using Analysis Variance (ANOVA) learning techniques, effects these UTS E were evaluated. Results highlight deposition angle dominant parameter, models, especially Random Forest Regression, providing highly accurate predictions. approach presents novel, data‐driven method optimizing 3D processes sustainable, materials.

The present study focuses on the mechanical and viscoelastic characterization of 3D-printed PLA, fabricated in three different printing orientations (0°, 45°, 90°) four nozzle temperatures (210, 220, 230, 240 °C). By employing a combination static dynamic analysis (DMA) testing, as well differential scanning calorimetry (DSC) analysis, this work aims to investigate relationship between processing parameters resulting properties PLA. DSC results showed that higher enhance degree crystallinity, which turn affects behavior Regardless temperature, flexural strength decreased orientation degrees increased. However, it was found for same orientation, smaller deviations per specimen. DMA indicated increased, glass transition temperature (Tg) values increased while storage modulus decreased. At time, both cases, by increasing an increase Tg respective is observed due crystallinity.

Additive manufacturing (AM), particularly fused filament fabrication (FFF), has gained significant attention for its design flexibility and cost-effectiveness. This study focuses on optimizing FFF parameters that employ response surface methodology (RSM) to enhance the flexural performance of polyethylene terephthalate glycol (PETG) parts. Three essential parameters—layer height, print speed, nozzle temperature—were varied, their effects strength, modulus, toughness ultimate at 5% strain, strain strength were evaluated. Based a Box–Behnken design, experiments revealed these mechanical responses. The analysis variance (ANOVA) indicates layer height predominantly affects modulus toughness, while temperature significantly impacts strength. RSM models exhibited high accuracy, with R2 values exceeding 99%. Optimal parameter combinations yield remarkable improvements: reached 39.55 MPa, peaked 1344.60 218.22 J/mm3, 381.47 3.50%. Validation confirm effectiveness optimization, errors below 3.17%.
