Numerical modelling of the viscoelastic polymer melt flow in material extrusion additive manufacturing

ABSTRACTIn material extrusion (MEX), it is challenging to accurately predict the steady and transient feeding forces at various polymer extrusion rates when printing island and thin-walled structures involving rapid start/stop or acceleration/deceleration, especially for semi-crystalline polymers. T...
