Fused Deposition Modeling (FDM) is a widely utilized additive manufacturing technique known for its precision and versatility in producing three-dimensional objects. Polylactic acid (PLA), a commonly used polymer in FDM, is valued for its ease of processing with excellent mechanical properties However at higher temperature (55–60 °C), the mechanical properties demonstrate a relatively low impact strength (< 10 kJ/m2) which can limit its use in applications such as the automotive and aerospace industries. Thus, carbon Fiber (CF) addition have shown excellent improvement in terms of Young modulus which reported between 200 and 800 GPa while their tensile strength reported between 1 and 7 GPa. Adding carbon fibre can significantly enhance its mechanical performance, resulting in a PLA/CF composite with improved tensile strength (exceeding 100 MPa), bending strength (exceeding 150 MPa), and impact resistance (exceeding 20 kJ/m2).
