Study of Mechanical Properties of 3D Printed Advanced Polymer

This thesis focuses on the mechanical behaviour of ABS which is an advanced polymer material produced by 3D printing. The ABS specimens used in this work were prepared by fused deposition modelling (FDM) to compare the compressive and tensile strength with ASTM D 695. Critical settings within the range of 3D printing process including layer height, fill angle and density were adjusted to investigate the impact on ABS mechanical properties. The effects of these parameters are observed to have a profound impact on the strength and the stiffness of the printed specimens. Further, the optimal conditions for ABS print were established to improve the mechanical characteristics of the material. This study observes valuable reference for adjusting the 3D prints parameters of ABS and it can be useful for the development of eco-friendly manufacturing practices. The optimal infill density stands at 34.5455%. These optimized parameters have demonstrated a 0.9265 desirability value indicating strong potential to achieve the target compressive strength of 10.7422 MPa. The results show that reaching target mechanical properties requires precise control of infill density together with raster angle settings.
