Researchers are investigating post-print annealing as a potential fix for poor adhesion between chopped carbon fiber (CCF) and thermoplastic filaments in 3D printing. Testing on PETG and PLA materials revealed that while PETG significantly benefits from annealing, adding CCF to PETG worsens its performance compared to plain PETG or even PLA-CF blends. This matters as it highlights the limitations of using CCF additives in FDM prints for improved mechanical properties, suggesting that alternative methods may be necessary for enhancing print durability and adhesion.
