Also a note: If you use anything other than Oomoo(shown) or Mold Max silicons from Smoothon.com, please be careful of using legos for molds. The Oomoo and Mold Max silicon is thick enough that it doesn't bleed through the sides, but other thinner silicons(like dragon skin) will. So be aware and test a small portion first if you're concerned.
While this is shown using Oomoo molds, I use Mold Max 30 for most of my mold making.
However, I do recommend using Oomoo Silicon if it's your first time making molds. It's cheaper and measured by 1:1 volume so you don't need to buy a scale for weighing your components. Just know that your mold will only last about 10 casts or 1 year before it starts to warp and tear.
If you want a tutorial on how to make a simple mold and work with silicon in general, check out Dan Perez Studios:
you can use the brush on kind if you want, but you'd have to use a mother mold of plaster or brush on resin in order to use it. It's a messy process, and kind of frustrating to do. It can potentially save you a little money, but probably not as much as you think.
Awesome thanks for the feedback! Yeah the whole money things a problem for me so I decided I better not try to make one just yet. Gotta be patient. I don't trust myself enough not to fuck up yet. I'll probably stick with clay until I'm ready.
How does the inside mold work? I get that you put the two pieces of the mold together, pour in the resin... and do you just set the core of the mold inside it? How does it not float around or push out your resin? Sorry this is so hard to grasp for some reason.
The inside is balanced inside the mold. I put keys on the plug so that when the inner part is cast it will fit snugly into the front and back of the mold. the keys keep it from moving during casting.
Oh, thanks. And you're good at explaining. I've understood a lot of what you've said in tutorials. And the videos with afternotes make perfect sense. Do you really only get 10 molds out of each casting silicone, or do you use a stronger one? And do you only sell dolls you can proffessionally cast? And one more... which type of resin did you use from Polytek? I'm trying to figure out which one of their fancy wordings is polyerthane resin for pouring. Thank you sooo much! I will cite you on my web site if thats okay with you.
