It's also reusable!
Here is a bit I made using ProCreate. Mold holds details really well!
Now the real deal here is that I wanna have something really simple. No resin measuring, no epoxy kneading, no plaster dust and no mess with clay. Enter My Dough!
It's one part, doesn't leave a mess and hardens without oven (also smells nice). These are the things I wanted out of the stuff. Pretty cheap too! 6€ for the tube.
It has its disadvantages too. It shrinks quite a bit, loses some of the sharpest details, and is somewhat brittle (I'd say in a ballpark of plaster). The shrinking is the thing though which makes it hard to use. For example that window frame above would never work with My Dough, since the mold don't allow it to shrink lengthwise, it'll rip itself apart.
And here's a copy of a thing that My Dough excels at. A simple stamp type mold.
Both have been made using the same mold. Shrinking is real!
Next up is something a bit challenging, barrels and boxes, and other more three dimensional objects.
