You have to see this stuff. It is so cool.

It is a biodegradable plastic (like nylon) that has a low glass transition temperature meaning that it get soft and pliable like putty at around 180 deg F. It stiffens at room temperature and it’s colorable. I hear it’s paintable but I need to do some experiments.


  • Re-usable
  • Can use hot water to melt it
  • Use scissors to cut it when warm
  • Use a Dremel tool when cold
