123-3D version 1.75mm PLA Thermoactive filament is made of PLA filament with added thermochromic pigment. This causes the colour to change when the surface of a 3D print exceeds 30˚C. The colour gradually changes back when the temperature cools down.
Key Features:
- Colour change at about 30˚C
- Excellent adhesion between layers
- Aesthetic appearance
- Does not deform or shrink
Applications: Ideal for making temperature sensors, educational projects, coatings for hot drink cups, coatings for kettles, thermostats and other electronic devices.
