Mesoscale Modeling of Extrusion and Solidification During Material Extrusion Additive Manufacturing

Recent Progress in Materials, 2023
In this work, we apply a multiphysics approach to fused deposition modeling to simulate extrusion and solidification. Restricting the work to a single line scan, we focus on the application of polylactic acid. In addition to heat, momentum and mass transfer, the solid/liquid/vapor interface is simulated using a front-tracking, level-set method.

Influence of plastic formation parameters on structural characteristics of thermoelectric material during hot extrusion

Modern Electronic Materials, 2017
We used mathematical modeling to compare the stress and deformation in a Bi0.4Sb1.6Te3 solid solution base thermoelectric material for extrusion through different diameter dies. The results show that extrusion through a 20 mm diameter die produces a more
