Thermoactive PLA

For everyone Thermoactive PLA

Spectrum Thermoactive PLA is a filament based on pure PLA blended with a thermochromic pigment. Due to this extremely original addition, additive manufactured items change their colour according to the temperature. For Spectrum Thermoactive PLA, the colour changes from red to cream once the surface temperature of the item exceeds 30°C. The previous colour is restored gradually once the item reaches its initial temperature.

    Thermoactive PLA advantage
  • made of biodegradable raw materials
  • printing possible without a heated bed
  • easy separation of the object from the bed
  • the capacity to change colour at the temperature of approx. 30°C
  • smooth surface upon printing
  • excellent layer lamination
  • no shrinkage
Elements produced by using Spectrum Thermoactive PLA are characterized by:
  • The possibility for the colour to change from red to cream when the surface of the printed item is heated,
  • Colour change rate adjustment by modifying the thickness of walls of printed items, and
  • Obtain mechanical properties close to those of items made of pure PLA.
  • High rigidity,
  • Brittleness and low flexibility especially after long-lasting exposure to UV rays, and a low content of volatiles in vapours during processing.
Due to the very specific qualities of Spectrum Thermoactive PLA, the material is mostly used in industrial applications where it is crucial to identify the condition of equipment visually based on phenomena measured organoleptically (the effects are visible with the naked eye here). Accordingly, it is used for the production of temperature sensors, rechargeable and non-rechargeable batteries, components of fuse testers, coating for hot beverage mugs, coating for kettles and thermostats for other electronic devices.
