RP List,
        I have a client that wants to build an SLA part that is a thin shell
that would completely entrap some liquid resin. Like a bowl with a lid on it.
 This would be built in ACES style, not Quickcast. Have any of you done
something like this? Could you build it like a trapped volume and then just
drill a hole in the bottom in the GREEN state and drain it before cleaning and
curing? Could you put vents and drains in it with the Quickcast software and
still build it in ACES? Would it be better to add the holes on the CAD end?
 How big do they have to be before one could single sweep again? Any tips for
removing the forever trapped supports in side a THIN shell? Many thanks in
