You probably want to start with an STL file importer to get
triangulated facets in an easily readable format.
Then, calculate all intersection points between a (Z-)level and all
the edges. Have an eye on rounding errors. Remember the facets these
points originate from to get ordered pairs (inside/outside known).
Finally, connect those pairs to areas to get a slice.

While it's not a rocket-science-level geometrical problem, I'm not
aware of code specialized for this task in the public. Code written
for 3D visualisation (OpenGL clones, for example) might help you,
however.
