This study investigates the thermo-mechanical behavior of acrylonitrile styrene acrylate (ASA) specimens fabricated using Fused Filament Fabrication (FFF). The influence of raster width, raster angle, extrusion temperature, and flow rate were analyzed using Dynamic Mechanical Analysis (DMA). Results showed that raster angle and extrusion parameters significantly affect the storage modulus and glass transition temperature. Optimal stiffness was achieved at 45° raster orientation, 0.5 mm raster width, 240°C extrusion temperature, and a flow rate of 1.00. These findings highlight the importance of parameter selection for improving the performance of ASA components in thermally and mechanically demanding applications.
