Answering late,

stl is a mesh: made of triangles, hopefully closed, and hopefully a
single part (well, it's a matter of constraint on printing).

I have done a STL export in experimental fork of povray, the hard part
is getting a mesh from the usual object (also in that fork a few mesh
creation mechanism from 3D finite shape(s), a few because not one is
perfect for all)

I did not tried to get the colours in stl (because I did not need it
for printing bronze, and also because there is two divergent colour
coding: VisCAM/SolidView & Materialise Magics)
