Best glow filament! No strings, great flow.

​I am really impressed with this filament. The flow is extremely consistent, which resulted in zero stringing on my print. It had great bed adhesion and stuck to the plate exactly like it should. The rolls are wound neatly, so I didn't have any issues with tangling, and it arrived perfectly sealed in the vacuum bag to keep the moisture out. ​I used standard PLA settings, and it printed my articulated snake perfectly. A few tips for others: ​"Charge" it up: You need to put the filament or your print under a lamp or in the sunlight to get it to glow. It won't glow on its own! ​Go Big for Colors: If you want to see the multicolor transitions, you need to do larger prints. On smaller items, you might only see one color. ​The Glow Color: In on of my photos, the snake looks white because of the lighting, but in person, it's a very bright, vivid glowing green. ​This is a very reliable filament that produces clean, high-quality results. Highly recommend!

This filament worked great in my Creality K1 using standard settings. The colors are bright and blend well together to create a cool print.

Quite awesome with the right models

The pictures don't do this filament justice. Yes on simple vase type objects you get a basic RGB coloring but it's much cooler than that on more complex shapes. For example, the visible colors change just from the print pattern changing directions and if you have something layered like this manta ray it looks like oil in water or almost like wood or even denim in certain areas. It's very cool and versatile.

Hello SM177Y! Wow, your description is fantastic! 😍 It’s amazing how the filament can look like oil in water, wood, or even denim depending on the print. Your manta ray sounds like a masterpiece! We’d love to see photos of it or any other creations—you’re inspiring us and other makers!
