This software considers all parameters that make a difference in the mechanical properties (print orientation, layer thickness, etc.) and gives you the actual properties for some specific print settings. As @OwenSmithyman mentioned, the mechanical properties depend on the print parameters heavily, so you would need to run many tests if you are using different parts with different print settings.
I don't think they have included Autodesk's resins in their materials library yet. However, they did include the Formlabs ones. They do accept people to send them materials samples, and I assume they would publish results based on that.
I am also interested in doing FEA simulations for 3D printed components. Since I am looking at many parts with many configurations, this program would save me the time to run the tests and derive the properties from there.
