Influence of silicon carbide reinforcement on mechanical behavior of 3D printed polymer composites

Abstract

Silicon Carbide reinforced ABS based polymer composite has been developed by Fused Deposition Modelling (FDM) technology. The percentage of SiC was varied between 0 and 4%wt in steps of 2%wt. Twin screw extrusion technique was employed to develop ABS + SiC filament suitable for FDM printing process. 3D printed pure ABS and ABS + SiC composites were subjected to tensile test as per ASTM standard. Results shows the SiC filled ABS composite provides remarkable improvement in ultimate tensile strength compared to pure ABS. Further, Ultimate tensile strength increases with increase in SiC content.
