Chris,
Take a look at layer 200, 203, 235 - 237 (this will most likely cause a print failure being so many layers that are unsupported), 235 (the bridge from un-supported to supported here is not going to be strong enough to pull the previously un-supported part off the PDMS layer). I think the model needs to be fixed before it will print reliably. Unless this is a PreForm problem and then the OP should open a support ticket. I saw the same problem in the picture I posted above using the same model.
