Any idea on how long does it last under direct sunlight? (i mean, the UV are nasty and easily destroy most resins in no time, and i don’t even want to know what they do to the dye itself)

The pigment changes even just holding it in the bag, so I imagine this would work. Let us know how it goes though if you try it out!

Would it be possibly to mix this with water and then run a current through the solution to create the same color changing effect?

Update: after months and hundreds of prints, the dye is starting to lose its morph. The center area of my bed, directly above the heating element, has become stuck in the “hot” state. However, the rest of the bed continues to work fine. I attribute this to the heating element getting only the center too hot and the heat not being even ( I often crank the bed up to over 100'C and my heating element does not cover the whole underside of the bed). I expect a more distributed heater, like a PCB reprap heater, would not have this issue and the dye would work well long term.

I successfully mixed this stuff with a clear powder coat. The stuff I used cures at 340F for 20min, which was not enough to damage the dyes (most powder coat cures at 375-400F, which is probably too high). The only issues I had was it shot a little bit clumpy (next time I will run it through a fine mesh sifter first) and the flow out developed a heavy orange peel texture instead of smooth gloss.

I’m using it on an aluminum heated bed for a 3D printer, so we’ll see how well it holds up to long term exposure to 60-100C temps….

Could i use this to dye the polymorph I got here? ;) edit: I read the description and it says polymorph :P sorry.

We gave it a try, just to make sure, and this stuff will DEFINITELY change color when you breathe through it! :)

I saw a video about a DIY Rorschach mask made with this stuff. http://www.youtube.com/watch?v=tWWLn7vt37U
