Materials testing of 3D printed parts
As with all AM related simulation existing FEM codes are not well suited to solving the material addition issue.

It is very hard for the codes you mentioned to simulate layer-by-layer and toolpath-by-toolpath material addition.

There has been significant research in AM simulation, most of it focuses on the metal additive manufacturing processes. The simulation of the entire build process with complex geometry and material addition almost never occurs due to computational cost. For example this work is one of the most sophiticated simulations developed and it is so computationally expensive that only a single laser scan was performed.

If what you actually want to achieve is stress/deformation of a FDM part then perform a structual analysis using anisotropic material properties that match that of your printed parts. I would assume that by now data for material properties of FDM parts with respect to machine parameters would be known at least for commonly implemented materials such as ABS and PC.
