摘要

Additive manufacturing techniques, particularly fused filament fabrication (FFF), have attracted a lot of interest due to their potential in producing high-performance composites. This research looks into the effects of build orientation on functional behaviors of fused filament fabricated (FFF) carbon fiber enhanced PLA composite. It is used in the production of orthotic devices and prosthetics due to its enhanced mechanical properties and biocompatibility, in interior and exterior car parts for their lightweight and stiffness, in lightweight drones and helmets for material durability and lightness, and in aerospace to reduce fuel consumption and improve efficiency. The CF-PLA specimens were printed using three distinct build orientations like flat, on edge and upright at 30°. The specimen printed with edge orientation exhibited a better tensile strength of 56 MPa, hardness of 78 HV. The edge orientated CF-PLA specimen revealed strong bonded microstructure and tribological behavior than other two orientations. These results demonstrate how important build orientation is determining the functional behaviors of CF-PLA composites printed via FFF, providing valuable insights for optimizing part performance in diverse applications.
