I bought this specifically to print my Red Tron identity disc in. It does not fail to impress. As with any glow in the dark filament, leave it out in the sun all day and it will be brighter and last longer. I just charged it for 20seconds in the photo. With exposure low the photo makes it look brighter of course, but the brightness from just a bright flashlight doesn't last long. The dull dim lasts for a while though.

Filament is wound on a cardboard roll and then the plastic spool is put on, when my printer is trying to pull filament from the edges of the spool, it gets caught and binds up, effectively acting like it's tangled, got close to ruining my y belt from skipping it jammed so hard on the spool. Also, the filament is red and the glow is a dull orange. I would only recommend most glow in the dark filament if you plan to use a UV light with it. Prints as well as any other PLA would, I do not recommend this for high speed printing (150mm/s+).

Prints nice, and it will glow if you charge it, but the glow doesn't last very long. You pretty much have to charge it with a flashlight for it to glow and that wears off fairly quickly. I

Good quality filament and glows really well after a charge from a UV light source. Only complaint is that the filament glows more of an orange color than red.

I frequently use the Sunlu red glow-in-the-dark PLA on my Bambu 3D printers, and the results are fantastic. The filament glows nicely for about one to three minutes after being charged under a light source. One thing to keep in mind is that you'll need to fine-tune your printer settings, as the filament can clog if the temperature isn't just right. Also, if you leave it unused for a few weeks, it can become brittle, so it's best to store it in a dry place and consider using a filament dryer before printing. Overall, it's a great filament with a beautiful glow

This was fun because when it printed it printed orange and the glow on it was really bright. This has more of an orange look and it worked really well for printing articulated lions and tigers. I had no issues printing with this and everything adhered perfectly.

Color is 100% orange, not red at all. Glow is the same greenish color that regular green glow filament has - looks kinda neat, but not a red glow which is what was described. Barely glows at all unless you hold a light directly against. Quality: Very transparent, need 8-10 layers to stop seeing through it. Prints fine and looks pretty good.
