    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.
