Which risk increases when amorphous polymer filaments in fused deposition modeling become cooled past the glass transition by convection?

A)Delamination between printed layers occurs✓

B)Increased nozzle clogging from backflow

C)Thermal runaway in heated bed develops

D)Oxidation rate in filament increases

💡 Explanation

Delamination risk increases because stresses accumulate during solidification after the glass transition; the high viscosity prevents stress relaxation via viscous flow; therefore, brittle failure leading to poor layer adhesion is induced; rather than other thermal failure.
