Word of warning, UV will stop the color changing. So if you leave it in the sun it will go to the warm color and stay.

I bought this to print some heart keychains for some friends and they came out great. The color change is just great and really impresses people. I am using it on a Ender 3 Pro and had no problems with it at all. If you want a fun filament, I would suggest getting this.

This filament is so cool! They designed the filament perfectly so it changes colors from room temperature/cold (deep purple) to bright pink/fuchsia at body heat temperature from holding it in your hands or against your skin. Tons of fun! I have many colors of PLA and this is by far my favorite. I have noticed it to be a bit stringy, but that can probably be tweaked with extruder settings and doesn't take away from how cool the product is. It is also very slightly translucent, which is fine but may be noticed more with thinner walls.

Got a roll of this stuff to print out some extra trinkets for girlfriend’s birthday. Super easy to print with and the color changing works better than others I’ve purchased. Super stoked with this stuff. Not sure why some complain about problems printing. Made me hesitant to grab this at first, but I’m not a 3D printing pro and got good results sooo who knows!Temp:210 Bed: 60 on semi-stock Ender 3 Pro

Purple yes. Red no. It’s pink definitely pink when heated

The color changes as advertised

This filament is purple to “PINK” NOT RED

My girls love this filament! I have made them a few lithophan pendants of The little Mermaid, Beauty and the Beast, and Cinderella. Also a bunch of animals for bathtime fun. Printed at 205, sticks well and so far only 1 random fail of the print popping off the bed out of many print jobs so far.
