The rapid development of additive manufacturing (AM) technology and the consequential microstructural variations have brought simulation aspects into focus. To capture an accurate mechanical response, multiscale methods are used to determine macroscopic constitutive behaviour. Among these methods, recently introduced Direct FE2 (DFE2) technique has shown some success in predicting material behaviour via direct incorporation representative microstructure volumes structure. present study highlights predictive modelling capabilities DFE2 linked with element elimination (EET) investigating performance fused filament fabrication (FFF) samples under tension compression. Parts were manufactured by FFF various raster angles vary failure characteristics. Their responses fracture behaviours simulated benchmarked against conventional FE, highlighting that results competitive FE. Most importantly, combination EET resulted insights regarding changes surface for varying angles.
