40–49cm Dolls 1/4 scale female doll

I am currently working on a 1/4 female doll. I want the head and face to be stylized but for the body to be anatomically correct.

Here is a photo of her face. This is the master sculpt of her head. The first two molds I made had issues, so I have yet to create a final mold.

I began to make a mold of the body, here is a photo of it set up in a mold box. The bottom is lined with plasticine, which is okay to use with non-porous materials such as resin. The holes in the neck, arm and leg sockets are blocked up with plasticine to prevent silicone from entering. The holes on the bottom are to create a locking mechanism to help align the two mold pieces.

Here is the silicone all poured, it took several pounds of silicone to complete.

Plaster casts, there were issues with air bubbles in the sculpt and unseen flaws in the master sculpts. This means the mold will unfortunately have to be redone.

I did some beeswax pours as well, beeswax is neater, doesn't trap air bubbles, and picks up on fine details better. In the future I will be using wax for test casts. This post will be updated in the future with the beeswax photos.

 

Here's the beeswax casts. It's difficult to see in these photos some of the very fine scratches that are present on the ribs and upper joint of the abdomen. There were also pits that were a result of air bubbles in the silicone. Beeswax must be poured in one go. It shrinks as it cools, and pouring it into the mold at different time intervals would result in very distinguished layers of beeswax.

 

Thanks!
Do you mean melting sculpting wax? I think it would still shrink. It may shrink less, but the heating process expands the wax, and then it shrinks back down when it becomes cold. If you carved wax, it wouldn't shrink as it starts off cool.

 

@Lillith - Thanks for the info!
