Polymorph (Polycaprolactone) is a non-toxic, biodegradable polyester with a low melting temperature of about 60°C (140°F). Prototype plastic parts can be made by simply heating in hot water until it is clear and then shaping by hand. When cool it becomes a nylon like white plastic. Polymorph can be re-used by simply re-heating and re-shaping.
