 PLA Thermochrome is a tough, easy to use high grade colour changing PLA type of filament. The dark grey colour will change to natural above 29˚C, but much faster above 33˚C or higher. Other features are according our slightly modified PLA product, so tougher and less brittle as a regular PLA. Due to a low shrinkage factor PLA will not deform after cooling. Poly Lactic Acid is a biodegradable plastic made from renewable natural resources and one of the most popular materials for 3D printing.

PLA Thermochrome features:

  • Colour changing grey-natural > 33˚ Celsius
  • Tougher and less brittle compared to regular PLA
  • Easy to print at low temperature
  • Low warping
  • Biodegradable
  • Limited smell

PLA Thermochrome is available in nearly any type of  packaging and labelling. Ask our team to help you customizing your product.

Additional info:

Due to its low tendency to warp PLA Thermochrome can also be printed without a heated bed. If you have a heated bed the recommended temperature is ± 35-60˚C.
PLA Thermochrome can be used on all common desktop FDM or FFF technology 3D printers.


Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.
