rhino + 3d printer

HI All,
I've downloaded rhino 4 and it looks that the tools to make a 3d
printer is there, just need a little to make it work.
I draw a part then saved as .Slc file then opened and hatch one
slice then saved as a windows metafile.
now, one could make a script to put each slc slice on a diferent
layer and hatch it up then print it.
Too bad it has only 25 savings.
How about that?
