dc.description.abstract | The aim of the present investigation is the development of a numerical model
able to adequately represent the effect of several variables, associated to the
fused deposition modeling (FDM) procedure, on the mechanical behavior of
3D printed parts. Specifically, 3D printed carbon short-fiber reinforced thermoplastic parts are numerically analyzed. Previous experimental results have
proven that this kind of parts show a global anisotropic behavior, in terms of
classical mechanical parameters as stiffness. Thus, special emphasis is done in
analyzing the effect of the raster angle / toolpath (inherent to FDM) and the
internal microstructure of the deposited filaments (due to the presence of the
short fibers). Multiscale finite element models are used to represent the linear
elastic behavior at macro scale. The numerical models are also able to include
the effect of porosity. Based on experimental results of 3D printed composite
parts with 100% infill and different raster angles, elastic transversely isotropic
properties are estimated for the individual deposited filaments using a reverse
engineering procedure. Obtained results show that for an adequate modeling of
FDM composite parts, anisotropic properties of the filament must be taken into
account, even when quasi-isotropic printing parameters are used (“cross-ply”
configurations). Finally, additional numerical analyses of some parameters associated to the FDM technique are done. Specifically, the effect of porosity related
to the infill pattern and percentage on the global (macro) apparent stiffness is
analyzed. | es |
