The stl2pov just turns the stl file into an object{}. Read through the
other code on the slicing page, and it describes how to create an
animation that will give you a series of slices.
Just replace the parts stating
object { m_Rhinoceros_Binary_STL___Jun_15_2005__ rotate 90*x }
with your own object, and you can create what you like.
A word of warning, the items you can create really depends on the
printer you have available. Something like Metatron is easier on a
printer where the printing media helps suspend the object until printing
is finished, like laser fusing or sintering. Machines that build the
object freestanding, material deposition, have difficulty with thin
objects and you sometimes have to add support pieces just to finish
printing.
