Basically surface is a calculation that uses the classical definition of a molecular surface based on probe sphere and atomic VDW radii, whereas molmap generates an approximate density map from the atom centers and allows you to show a contour surface of that density map.
Further details in their manual pages:

I read through the forums and it seems that using the split command is the way to go, but I would not like to split this antibody. I'm trying to get a full rendition of the surface model of the antibody so that it is possible to 3D print the antibody. Can you please let me know if that would be possible? The pdb files of the 4 antibodies are attached.
