This was a fun one - but also posed a few challenges. Number one of them is all the little teeth and horns. I wanted to pressure cast the figure to preserve this detail in the casting, but the size of the figure meant that quite a lot of material would be needed. It would have to be hollow - but how?
TL;DR - Finished pictures are at the end.
Sculpting Process
Sculpted in monster clay over a tin foil armature.
Molding and Casting
Because the figure has lots of little thin protruding teeth I wanted to pressure cast it for the best possible reproduction (that I can manage myself) That also meant a slush cast was out of the question. So the casting and molding process was such that the figure had to be hollow!
Firstly, there were a lot of undercuts in the figures mouth - look at all that. These were all sliced off in sections prior to molding the body.
I block out my molds to save as much silicone as possible - it works but it could be more tidy.
To be able to make a hollow cast I needed to make a positive core to use inside the mold during casting. This was done by pouring liquid monster clay into the mold to create a shell of the desired thickness. Then a plaster cast was taken. When the monster clay was removed it left a void between the silicone mold and the plaster positive. Holes were drilled into the plaster to pour the resin in to. This was my rough and ready way to make a hollow pressure cast mold.
The cool thing about this is the casting in Monster Clay is a cool way to potentially cast and modify old sculptures - FUN.
Completed Cast
Painting
A painted this thing with a mixture of Vallejo and Citadel acrylics with an airbrush and later by hand with various washes to get the details out.
The base was made in such a way so that there would be no visible armature - It's a floating character but I didn't want to have even a clear acrylic rod sticking out of the bottom. Instead the creature is supported by metal rods up the supporting arm and a pin in the elbow of the other arm to secure it in place.
Finally, I made a little DOOM logo out of styrene.
