Review on 🌈 AMOLEN Printer Filament: Innovative Sunlight-Activated Color Changing Technology by Darth Naubert

I actually ordered kit A but they sent me B instead. Due to low stock of A there were some issues with Revain bulbs and Tri Color Change Lava sounded interesting. You must properly configure the slicer settings for these threads. My attached photo shows the temperature towers ranging from 220C to 180C from bottom to top. From left to right: Tri Color, GitD Blue, GitD Green and Marble. I've had a lot of viscosity above 210C. The weird ripples seen in the image at higher temperatures are partly an octoprint artifact that pops back into the center for photos, so ignore that. The TriColor had major problems when it got too cold, but 200C seems to suit my Prusa i3 MK2S. Also, I measured all the threads with calipers and they appear to be 1.71mm. After changing this in PrusaSlicer my prints look much better. I love the fact that they come in smaller spools, especially with colors that I consider new. I don't print often, so I don't buy in bulk. As for GitD Blue, you need to manage your expectations. GitD Blue glows much dimmer than Green. I knew beforehand. However, it is quite a blue glow. As for GitD Green, I suspect it uses zinc sulfide as its phosphorescent pigment. It turns out a good green color. I have GitD Green from another manufacturer which glows brighter and has a slight blue cast (probably strontium aluminate for the pigment). The difference could also be due to the amount of pigment present, but I can't measure that. In any case, more GitD pigment also means you can ruin the brass nozzle faster (there are several YouTube videos on this). I did a crystal print with this filament (time lapse video attached) with a bright UV LED to keep it charged and it looks pretty cool. The print is clean. Marble. I don't know how much of this I'll use, but it printed fine. I bought the kit mainly for other coils but it's good to have in my back pocket in case I need it. Like most "marble" strands, it looks more like a speck/pepper than a swirling marble. Tri Color Lava is pretty neat. The darkest thing he gets is sooty charcoal. It's fun to watch the gradient as you print. I've made some geometry puzzles with this thread and it's fun to watch the color change as it takes people time to solve. I suspect this happens with overlapping dark to light and orange to yellow pigments. It takes quite a bit of heat to turn fully orange, and even more to turn yellow. I think this would be a great thread for electronics cases (especially something like the Raspberry Pi 4) to keep track of hotspots. Update: Added a photo of what I suggested. I designed the RPi4 case (you can find it in the Prusaprinters models repository) and used Lava thread. The processor recorded 64C under load. The transition to yellow was somewhere around 54°C. You can clearly see the hot spots with this thread, which is pretty cool (hot?). This has helped me develop better ventilation.
