Skin Casting
Soft surface research
In simple terms, Auxetic materials are structures with a Negative Poisson's Ratio (NPR).
Unlike conventional materials (like a rubber band) that get thinner when you stretch them, auxetics do the opposite: they get wider when stretched.
This "counter-intuitive" behavior is achieved through their internal geometric structure (like re-entrant hexagons or rotating squares) rather than their chemical composition.

Casting
I try to cast in a whole skin like a eggshell in Wildcard week but failed. Because it lack of liquidity, and also hard to demold. Then I have to try another method.
I have a new idea for making skin. Since casting it in one piece is difficult, I can try dividing it into three parts, each cast as a flat piece of skin.
When 3D printing the mold, change the wall generator as Arachne, to make sure the very thin cut line can be printed.
