I made an art toy scupture of Junkbot, one of my Robot Roundup characters.
I started by printing out the vector drawing of the character at the size I wanted the sculpture to be. I used this as a schematic so that I could measure his proportions against the print out.
Except for some screws in his arms, legs, and neck, he’s made entirely from polymer clay, even his inner wires. Using a clay extruder tool, I made a bunch of “noodles” that I used to coat his insides with a messy nest of wires. I then made some thicker ribbed tubing by twisting a noodle around a thin wire.
After the clay was cured, I coated him with thinned modelling putty, dabbed on with an old paint brush. This added a kind of cast iron texture.
I airbrushed him with various rust and orange colors and then used thin washes of oil paint to add grease and rust streaks.
