I remember from reading MR particularly when using resin for water features that the trick is to pour the resin down a stick of some description so that you can direct the flow but not introduce air bubbles.
Another trick particularly for plaster is to attach the formwork to your electric sander and let the vibrations float the air bubbles up and out of the mix. This may also work for resin.
Hope these tricks help
I had to break out some polished concrete paving last week [oh my aching back] and it was interesting to see trapped air bubbles in the concrete where the vibrator had not floated them out. So bubbles can be a problem in anything you pour into a mold for casting.
