The following two-lobed blob is the union of two spheres, and it appears (?) that I can Export[] it to STL for 3d printing:

blob = Graphics3D[{Sphere[{0,0,0}, 1], Sphere[ {0,0,0.5}, 1]}]

How would I create the intersection instead of the union?

You could try using geometric regions:

 RegionIntersection[Ball[{0, 0, 0}, 1], Ball[{0, 0, 0.5}, 1]],
 MaxCellMeasure -> 0.0001

Export["blob.stl", %];

reimported region
