About Color-Changing PLA

Material Overview

Color-Changing PLA, also known as tri-color PLA or temperature-sensitive PLA, is a type of filament that exhibits color changes based on temperature variations. This unique material is typically printed in black and undergoes a transformation into different colors as the temperature rises.

Color Change Behavior

Here is the color change behavior of Color-Changing PLA filament:

  • Temperature below 33 °C: The filament appears black.
  • Temperature between 33 °C and 45 °C: The color transitions from black to orange.
  • Temperature exceeding 45 °C: The color further changes from orange to yellow.

It's important to note that the specific temperature ranges and color transitions may vary depending on the manufacturer and formulation of the filament. Additionally, the color change is reversible, meaning the filament will revert to its original color as the temperature decreases.


Color-Changing PLA is often used in various applications where temperature monitoring or visual effects are desired. Some common applications include:

  1. Decorative and artistic prints: The color-changing properties of the filament can be utilized to create visually dynamic and interactive prints, adding an element of surprise and novelty.
  2. Temperature-sensitive indicators: This filament can be used to create temperature-responsive labels or indicators that change color when exposed to specific temperature thresholds.
  3. Educational purposes: Color-Changing PLA can be used in educational settings to demonstrate the effects of temperature onmaterials or as a tool to teach concepts related to thermodynamics or temperature-sensitive materials.

It's important to note that Color-Changing PLA's primary characteristic is its temperature-dependent color change, and its mechanical properties and performance are generally similar to standard PLA filaments. Therefore, it can be used in a wide range of applications where PLA is commonly used, with the added benefit of the color-changing feature.
