3d printed material for FEA

[Sungod3000]

Hi,

I just watched a seminar on FEA and while I certainly can get some results by simulating my parts with ABS or the plastic material that the fusion library offers, I wonder how I can better estimate FDM 3d printed materials.

First I imagine it could be helpfull to weaken the material a bit to accomodate for the weaker layer adhesion compared to solid materials

and second similar to tree rings in wood the print orientation influences the strength, so is there way to simulate make the material weak from one side and strong from another?

Cheers

To my best knowledge, the current SIM environment is limited to isotropic materials (Material Properties are the same in all directions).  

You can make a feature enhancment request via the Fusion 360 Ideastation, below.

Let me know if you do and I'll add my vote to the suggestion!

Other assumptions for Static Linear Solvers:

• The deflection and stress are linearly proportional to the load. If you double the load, the deflection and stress double.
• Material properties are linear. The stress-strain curve is a straight line with the stress remaining proportional to the strain. There is no yielding of the material.
• The loading is static and it is applied slowly. Dynamic loading effects, such as a sudden load application or impact, are not considered.
• Temperature has no affect on the part geometry or material properties.
• The deformation of the part is small compared to the dimensions of the part. Large deflection requires a nonlinear analysis to account for changing part and load geometry, and it is not considered during linear analysis.
• Buckling is not a concern.

I hope that helps. Please let me know if you have any other quesitons.
