You could use transparent and partially opaque colors for dead and live cells, which lets you see the interior 3D structures more clearly than purely opaque 3D printed structures. I think the optical quality would likely be a lot better than anything I've seen 3d printed. I'm interested enough in this idea to see if I can come up with some interesting figures to make.
