If you are using Mechanical, insert a total deformation result at each second. (You can do this manuallly, by adding a result and changing display time or by  right-clicking and selecting Create results at all sets)

This will create a result at each load step.

You can then right click and export STL on each result. Please note, the STL is exported at graphics scale so use True scale for exporting STL.

Also, I am not sure what FEM format you are referring to.
