Influence of 3D Printing Parameters on the Tensile Performance of ASA Specimens

This study investigates the tensile behavior of Acrylonitrile Styrene Acrylate (ASA) specimens fabricated using Fused Deposition Modeling (FDM). The Taguchi Design of Experiments (DoE) approach was applied to systematically vary key printing parameters, including layer height, nozzle temperature, printing speed, infill angle, and build orientation. Standardized ISO-type specimens were produced and tested in tension to evaluate the influence of printing conditions on the material’s mechanical performance. The results indicate that printing parameters affect the tensile response of ASA, highlighting the importance of process control in achieving consistent mechanical behavior. The study provides a basis for future optimization and modeling efforts aimed at improving the performance of FDM-printed thermoplastic components.
