RE: Artificial ice shapes using SLA

We've made both model scale and full scale ice shapes from SLA. The
model scale pieces get used once because they are destroyed during the
removal. We usually tried to orient them in the build with the wing LE
(mating surface) up so that the mating surface was smoother while the
actual ice shape was rougher due to supports and bacon bottom effects.
The aero guys really liked the rough finish. As far as I know the full
scale ice was utilized for flight test with a little help from some glue
and speed tape. I know we didn't do the whole wing span...10 feet or so
is what I remember.
