This research investigates the mechanical characterization of CF-PLA (Carbon Fiber-reinforced Polylactic Acid) composite material produced using Fused Deposition Modeling (FDM) technology. The study investigates the impact of different machine parameters, like nozzle temperature, nozzle diameter, and layer height, on the tensile property and hardness of CF-PLA specimens. A total of 27 samples were produced, each with different combinations of nozzle temperature (190°C, 200°C, and 210°C), nozzle diameter (0.4mm, 0.5mm, and 0.6mm), and layer height (0.1mm, 0.2mm, and 0.3mm). The specimens mechanical properties were assessed through tensile testing and hardness evaluations. The results indicate that variations in nozzle temperature, nozzle diameter, and layer height significantly influence the mechanical performance of the CF-PLA material. Tensile testing reveals a clear trend of increasing peak load and ultimate tensile strength with higher nozzle temperatures and decreased layer heights, emphasizing the crucial role of printing parameters in mechanical strength. Shore D hardness test results demonstrate consistent hardness values across samples, with average hardness ranging from 79.67 to 82.167. The quantitative analysis underscores the multifaceted nature of CF-PLA materials, where tensile strength is influenced by printing parameters, hardness remains relatively stable. These findings are pivotal for optimizing material compositions and fabrication parameters to tailor mechanical properties for specific applications, ensuring enhanced performance and durability in diverse engineering contexts.
