SUNLU Glow in The Dark PLA Filament, Neatly Wound Luminous PLA 3D Printer Filament 1.75mm Dimensional Accuracy +/- 0.02mm, Fit Most FDM 3D Printers, 1kg Spool (2.2lbs), (Blue PLA, Glow Blue)

The color on this filament came out really nice, and the glow effect is actually better than I expected. Prints came out clean and consistent with no major issues. If you’re using a Bambu printer, I’d recommend running this on an external spool instead of through the AMS. It feeds better that way and helps avoid unnecessary wear. Overall, solid filament if you’re looking for something with a nice glow effect and good print quality.

I frequently use the Sunlu blue 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!

I live this stuff. It's not the brightest glow in the dark ever, but that's fine. Leave it under a black light for a few hours before it gets dark and voila! I printed a Tron Legacy identity disc with it. I also bought GITD Red to print a red disc. Have zero issues printing it, No stringing, no clogging. I've even used it to print Hueforge which Prince had 0.08 mm and have zero issues doing that.

I wanted to give this filament 4 stars because the spool arrived messy and I fear a tangle in my future..but it printed perfectly and glows brilliantly. I glows way better than anything I've used before. I experienced no warping and it adhered to the bed with ease. The dark pictures are after I lit up the filament for 5 seconds with a standard led flashlight.

It glows, but not great…but otherwise it’s fine.

This filament does exactly what you buy it for…excellent glow characteristics. I have a Bambi Labs printer and accidentally printed this first model under a Silk filament profile which led to some stringing as the hot end temp was a little too high, so I will be printing with a standard PLA filament profile going forward. I would also highly recommend you use a stick adhesive on the bed to ensure first layer adhesion, especially if your models have any rafts for small parts or delicate supports.

There are three problems with this filament: (i) Took weeks to arrive. (ii) It does not have a strong "glow." (iii) Critically, it is so abrasive that it damaged the AMS feeder within the first 300 gr of use. I did not get to use have a spool that I get an error message that the filament gets stuck. Now I have to spend $50 and a few hours to replace the feeder funnel unit on the Bambu Lab P1S.

I gave a similar review on the glow in the dark red, and I again want to start off by saying I’ve had good experiences with Sunlu filaments in the past, but this wasn’t great. Constantly clogged my extruder and I couldn’t finish a single print. To note, I did dry the filament TWICE, wiped it down to remove any debris and went as far as hanging it outside my Dremel3D20 just incase angling of feed was an issue, I also did set the print temp to 210 celsius. Overall, the color and glow was great! but the quality of the filament just wasn’t it. I think it’ll be decent for smaller items but any large prints just wouldn’t work, at least on my printer.
