One easy way is to create new artboards sized to the dimensions of each panel and then export them.
The first step is to divide the artwork into individual panels and turn each panel into a symbol. While mapping art to the Bevel & Extrude effect is possible in previous versions, the technique detailed here for creating the symbols is specific to Illustrator CC 2017.
