    Premium 3D Printer Filament 1.75mm 0.5kg/spool, Color Changing Thermochromic Gray

    Create temperature sensitive objects on your 3D printer using this 1.75mm Color Changing PLA Filament from Monoprice!

    PLA is a good choice for a printing material if you are looking for high accuracy and high resolution. It extrudes at lower temperatures, does not require a heated base, and has a very low shrinkage rate (0.3%). PLA is harder than ABS, but is therefore also a bit more brittle.

    The negatives of using PLA is that it is vulnerable to degradation from moisture, sunlight, and heat. Additionally, it is more prone to overheating during processing, which can cause dripping and drooping if it gets too hot.

    This filament is thermochromic (temperature sensitive). Under normal conditions it is a gray color, but when exposed to heat it quickly changes to a neutral/whitish color. When exposed to freezing temperatures it changes to a dark gray. It comes on a 0.5kg spool and prints at temperatures between 190 ~ 220°C.

    Reel Dimensions:

    • Spool Diameter: 200mm (7.87")
    • Spool Width: 37mm (1.46")
    • Hub Diameter: 53.5mm (2.11")
    • Hub Width: 37mm (1.46")

    Color change is fast with heat, slow with cold.
    This color changing gray-to-white filament is black on the spool, and prints white. It took about 12 hours for the cooling print to turn gray. The filament strand has a coarse texture compared to ordinary PLA, but that doesn't affect printing. It prints just like ordinary PLA. I printed at 200°

    I made a holder for a paper coffee cup. When exposed to hot coffee temperatures in turned white in a few seconds. When the heat was removed, it turned back to gray in a few hours.

    I took off a star, down from 5 stars, because I hadn't expected the change back to gray to be so slow.

    Good quality PLA filament but...
    Its easy to make it grey by just putting it in the fridge for a while. But getting it to turn white is a bit more difficult to apply heat without melting it. Prints as well as the other MP PLS filament though. Don't think I will buy more.
