I would need some guideline for the molding process of my Plastiline statue.
I’m used to do silicon mold with plaster reinforcing shape for portrait or bust but here I’m facing a lot of undercuts.
The figure is a women sitting on a box, she rotates her bust to look behind. Her right arm laying down on her bust grabs her left leg and her left arm behind her back (see images below)
I’m planning to cast in Aqua Resin (stronger than plaster)
what molding technique should I use to manage these undercuts? Should I cut arms, legs and make separate molds? In that case how possible is it to paste all the pieces back in acqua resin? Or instead should I build the silicon mold in one piece and then manage the undercuts as shown in Matt Lewis video course?
Plastiline that contains sulfur may interfere with silicone. I guess you already knew that, due to you mentioning that you’ve already done some molding with silicone but I thought I’d mention it, in case that this is your first plasticine sculpt. Sadly I can’t give you advice regarding a certain technique for undercuts.
