Abstract

The study explores the impact of hybrid reinforcements, including silicon carbide (SiC) particles (0.5 wt%, 1 wt%, 1.5 wt%) and graphite powder (0.5 wt%), on the mechanical properties of 3D-printed polylactic acid (PLA) structures produced via fused deposition modeling (FDM). Composite filaments were fabricated using a twin-screw extrusion process to ensure uniform dispersion of reinforcements. The study evaluates Shore D hardness and flexural properties of these hybrid composites. Results indicate significant improvements in mechanical properties with increasing SiC content, attributed to the synergistic effects of SiC and graphite reinforcements. The findings underscore the potential of hybrid PLA composites for applications requiring enhanced flexural strength.
