Spectrum 3D filament, PLA Thermoactive, 1,75mm, 500g, 80171, rot

Thermoactive PLA is a filament based on pure PLA mixed with a thermochromic pigment. Thanks to this extremely original addition, additively manufactured objects change their color depending on the temperature. Once the surface temperature of the object exceeds 30"C, the color changes from red to cream. When the object returns to its initial temperature, the previous color gradually restores.

Thanks to the thermochromic pigment, printed objects gain the following properties:

• Ability to change color from red to cream when the surface of the printed object is heated


• Adjustment of the color change speed according to the wall thickness of printed items

• Smooth surface after printing


• Warp-free printing


• Excellent layer adhesion


• Ability to change color at 30"C


• High aesthetic surface quality


• No shrinkage after cooling


• Mechanical properties close to those of pure PLA objects

• Where visual identification of device status is critical (effects visible to the naked eye)


• Educational projects


• Temperature sensors


• Coating for cups for hot beverages


• Covering for kettles and thermostats for other electronic devices

• Filament diameter: 1.75 mm


• Density: 1.24 g/cm³


• Extrusion temperature: 190–220"C


• Bed temperature: 0–45"C


• Printing speed: 40–110 mm/s
