When I originally sculpted the figure which I take my name from, the Jumper (actually a Canadian Forces SARtech in jump gear) I had no idea it would be so popular. Now I find myself needing to cast more than originally thought, and though the Smooth-on resin I use is just a bit thicker than water I still have some bubble issues, no matter how carefully I mix and pour. This adds to the prep time and the "darnit" factor.
I use Rebound for the mould, with Shell Shock for the mother. I have been using Smooth Cast 325 with Ease Release. I tried the primer trick that the Smooth-on website suggests but with no luck. Also tried the talc, also no luck. It's a two part mould with no sprue. Mould is 12.5 inches tall by six wide by five deep. Figure is around 11 inches tall by three wide by three deep and irregular.
Given that I will be looking at making a generous number of these, and also since I've always wanted to get into larger production of some of my other pieces, I'm beginning to think about other ways of getting bubble-free.
Vacuum? Pressure pot? Centrifuge? 3-d printing?!
