   Actually, no, they don't.  What you are describing are later attempts   
   to replicate Damascus steel by pattern welding that did not produce   
   the same stuff at all.  No one knows how to make the original Damascus   
   steel.   
      
   As far as that goes, that's not what 3D-printing does, either, except   
   at the very extreme that says everything is made that way.
