Suggestions:
Try sealing LOM with shellac spray can or brush
For release try Petroleum Jelly not too heavy
Demold as soon as possible

> Dear RP'ers,
> We are trying to produce silicon replicas from our LOM models to be used
> sand casting. The process involves first silicon mold production which
> is the negative of LOM model and then casting resin into that mold
> several times (20-25) to have multiple copies. However, we experience
> difficulty when separating LOM out from silicon mold. LOM models are
> only coated with lacquer. Does anybody use a special separator coating
> or process for such applications?
>
> Another question: Does any 2030H user experience shifting in dimensions
> especially while building large envelopes? Any tip to fix it?
>
> Thanks in advance,
