- Treated papers are available for computer printers, especially for ink-jet printers. They absorb the ink and generate crisp colour reproduction.
- Thermochromatic pigments. At normal room temperature the pigment shows its usual colour, but when heated above 27°C the colour changes to black. When the temperature falls below 27° C again the colour reappears.
- Phosphorescent pigments glow in the dark, first absorbing light and then emitting it after the light source has been removed.
- Thermocolour sheet is one that changes colour as the temperature changes.
- Polymorph is a plastic that becomes mouldable at 62°C. It can be used for product-modelling, especially where curved shapes are involved (for example handles), and for making simple moulds for vacuum-forming.
- High-density modelling foam is a foam-based material that is available in blocks. It can be shaped easily using hand and machine tools and takes fine detail well. It is often used on CNC milling machines.
