Sculpting: Control Panel
I have been playing around for literally years trying to sculpt and cast miniatures / scenery bits. I have been plagued by (amongst other things) silicone leaks, air bubbles and sheer clumsiness. Today I have won a hard-fought victory against air bubbles! When putting resin into a silicone mold, air bubbles get trapped in all the hard-to-reach places. I tried a few things to get rid of them: Pouring a little resin in, then 'rolling' it around the mold by tipping it all different directions. It spilt some resin, and took up some of its valuable pot-life. Results: poor (although it might work for larger models). Adding flow-channels to model/mold. This involved cutting away channels of the mold, or adding sprue-like protrusions to the model itself when making the mold. It was very hit-and-miss, with some larger models coming out great some of the time. Air would still end up getting trapped though, and the channels meant extra resin ...
