Molding prosthetic ears with deep undercuts
This sculpt has some pretty deep undercuts. I'm planning to cast the final prosthetic in silicone, so if i'm using silicone for the mold, I very definitely need to be able to get mold release ALL the way inside. I don't think a block mold is going to cut it - would it be better to pour the mold in multiple parts*? or do a glove mold?
* I know it will have at least two parts, the silicone and the plaster ear form - I'm trying to figure out if the silicone should be in multiple parts too, and if so, where to put the seam.
(I'm also happy to get any feedback on the sculpt - I'm not sure if I've chosen good locations for the edges etc.)
