Although I do have limited experience with 3D modeling, I'm very new (about 10 days) to using Blender 2.8
I learned how to export character models from Overwatch and import them into Blender. So far so good; I can see the mesh, the UV map, the rendering pipeline, and so-forth. I would like to export the mesh to an OBJ file or an STL file for my 3D printer's slicer to work with. However I realized that a lot of the fine details were missing. That lead me down a long dark tunnel of normal (bump) mapping, rendering, and displacement maps that left me more confused than before.
Below three images are attached. You can see that the exported OBJ is identical to the original object mesh. However the rendered image has a normal map applied that provides more detail around the muzzle of the blaster.
My question is this: Does Blender (or any other 3D editing program) have the ability to export an OBJ after applying the the normal map so that the fine details are captured for printing?
UPDATE: I attempted to apply the existing normal map as a displacement per @Duarte's suggestion below. The only effect was to completely distort the model. Fourth image below shows the result.
