Assessing nozzle flow dynamics in Fused Filament Fabrication through the parametric map \(\alpha-\lambda\)

Polymer rheology profoundly influences the intricate dynamics of material extrusion in Fused Filament Fabrication (FFF). This numerical study, which uses the Giesekus model fed with a full rheometric experimental data set, meticulously examines the molten flow patterns inside the printing nozzle dur...
