This video critically examines the popular perception of PLA carbon fiber (PLA CF) reinforced 3D printing filament, arguing that it is an even bigger scam than previously thought. By conducting bending tests, microstructural analysis, and CT imaging, the creator demonstrates that PLA CF does not improve mechanical strength, stiffness, or impact resistance compared to regular PLA. Instead, carbon fibers disrupt layer bonding, create voids, and lead to stress concentration, ultimately weakening printed parts.
