A thermo-rheological model for predicting extrusion force in fused filament fabrication

We present a thermo-rheological model to predict the extrusion force required for polymer flow in fused filament fabrication hot ends. To capture the complex rheology of polymers, the model accounts for their yield-stress-dominated, solid-like behavior below the glass transition temperature and their shear-thinning beh...
