Computational characterization of polymeric materials 3D-printed via fused filament fabrication

This work develops a novel homogenization-based computational strategy for predicting the mechanical properties of fused filament fabricated parts by characterizing the component according to the different printing patterns used. The anisotropic constitutive material models obtained for each printing pattern allows the accurate prediction of the behavior of the entire component. The model is validated against experiments with the samples manufactured according to corresponding printing patterns. Various materials including Polycarbonate/Acrylonitrile Butadiene Styrene and ULTEM 9085 are tested. The good accuracy of the predictions obtained using present approach indicates that material characterization can be successfully performed in a fully numerical way.
