However, from the prosthetic and hand made robot field comes a really nice material that is:
Quick to prepare
Safe to use
Strong and flexible
Re-usuable when you get it wrong
Cheap to buy
Safe to keep
Bio degradable
What is the Super Material? They call it Polymorph.
What is Polymorph?
Polymorph is a thermoplastic polymer that melts at around 62°C. Its generally supplied as small off white plastic granules. Polymorph is non-toxic and completely biodegradable. Suppliers also tend to supply a range of coloured powder additives if you want to colour it, or it can be painted.
How do I use Polymorph ?
- Heat water to just over 65 degrees
- Add the opaque white pellets to the water
- Leave the pellets in the water till they turn transparent
- Remove the pellets from the water and mould by hand
- add colour if required)
- Allow the Polymorph to cool , it will turn white and solid
- Re-heat if further moulding is required
Its also very cheap, and if you screw up using it, you just chuck it back into a cup of hot water and start again, its that simple.
