ABSTRACT
Parts produced by material extrusion (FDM/FFF) are built layer by layer, resulting in direction-dependent mechanical behavior. Reliable finite element analysis therefore requires an anisotropic material model. In engineering practice, however, calibration data are often limited to a few directional material properties provided in the filament manufacturer’s datasheet. This work investigates whether a usable anisotropic material model can be created from such limited data and for which loading cases it can be applied.
