Something else to print with. Just for entertainment I picked up several rolls of color changing PLA filament. They are temperature changing, UV reactive and Glow in the dark. The photos show the changes. The UV and Glow photos are under a black light and everything is laid out on a chart to show the before and after colors.

Pretty cool! I have some glow ion the dark green, and some of the natural to purple, and it works great. This is a nice writeup for those looking to see what the changes actually are.

Those two UV ones are ridiculously fast in the sun or a powerful leak detection light. I also put together a single cut sheet, very badly edited, to show the before and after on the same sheet.

How about longevity for thermal activated? The old hypercolor pigment used in clothing was done in a year.
