Functional and Adaptive Filaments: Mechanisms of Failure and Thermomechanical Stability
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. Chamber heating does not improve the situation and may worsen the problem. Structural discontinuities generate localized stresses, especially in the filament path curves
