Blender's modifiers are programmed to modify objects in certain ways, don't expect any of them to be available outside of blender. You should always apply any modifiers before trying to share data with other programs.
Every modifier in blender has an apply button that will permanently alter the object to match what the modifier generates.
If you are using several modifiers you may want to use "Convert to Mesh" (press AltC). While this sounds odd when you already have a mesh object, it will apply all modifiers on the object.
