Composite filaments for FDM 3D printing, enriched with carbon or glass fibers, exhibit brittleness and risk of breakage during printing due to poor integration between additives and the polymer matrix. Heating the chamber does not improve the situation and can worsen the problem. Structural discontinuities generate localized stresses, especially in the curves of the filament path
