Viscoelastic simulation and optimisation of the polymer flow through the hot-end during filament-based material extrusion additive manufacturing

Viscoelastic simulation and optimisation of the polymer flow through the hot-end during filament-based material extrusion additive manufacturing

This paper presents a novel Computational Fluid Dynamics (CFD) model that simulates the non-isothermal flow of a viscoelastic fluid through the hot-end in filament-based Material Extrusion Additive Manufacturing (MEX). The hot-end is an essential part of the printhead, as it melts and extrudes the p...
