Hi everyone, I'm new at this hobby. I'll start having some of my own objects printed soon.
I want to try the White Strong Flexible material (WSF) for my mold-making/resin-casting projects.

My question is:
Will the white-strong-flexible material printed model hold up well inside
a silicone rubber mold as the mold cures?

(Before I begin the mold-making process I must coat the original object with
a mold Release Agent. The Release Agent will prevent the silicone from sticking
to the original object, thus making it easier to remove the object after the
silicone rubber mold has cured.
I'm worried about the possibilities of the Shapeways object getting damaged
from the chemicals in the silicone rubber while the mold is curing.
The mold takes about 18 hours to cure... I usually let it cure for 24 hours maximum
before I remove the object from the mold.
For reference, I'm using the Alumilite silicone rubber mold-making kit.


Thanks in advance. Smile
