Color: Glow in the Dark - Green to Glow Green

Consistent quality. Long lasting glow. Feeds from AMS / CFS without any issues. In the photo, it looks like two green spinners, one is yellow. Poor low light camera phone issues.

Good price, and pretty good glow in the dark strength as well. No issues getting this to print, and it looks great. Used it for some little toys and what not and it worked great

Color: Rainbow 01
Material Type: Polylactic Acid
I’m very impressed with the SUNLU Rainbow PLA filament. For the price, this filament delivers excellent quality and eye-catching results. The color transitions are smooth and vibrant, making prints look great right off the bed without any post-processing. The filament feeds consistently, prints smoothly, and adheres well with standard PLA settings. I didn’t experience clogging or tangling, and the diameter consistency seems solid throughout the spool. Layers come out clean, and the finished prints have a nice glossy look that really shows off the rainbow gradient. Overall, this is a fantastic value for anyone wanting colorful, reliable PLA without paying a premium. Definitely a great bang for the buck, and I would happily buy it again.

The filament comes neatly wound and prints well out of the box (SUNLU is generally great about this). For the white-to-glow variants you may find success printing with more solid layers or a higher infill percentage (even 100% solid for smaller prints) as this appears to produce a more consistent glow effect. The glow is very bright, especially if charged under sunlight for a little while! NOTE: if you print with 100% infill or have more than 2 solid shell layers, you may want to adjust your flow constant by 3-5%. I had excellent results bringing down the flow constant to 95% of the default setting. I think the additives to make glow in the dark PLA make the extruded filament a little rougher and less viscous in consistency, and the overextrusion was initially noticeable in more solid prints. It may seem wasteful to do so, but printing with 100% infill really does lead to beautifully illuminated parts. The infill pattern/lines can still glow pretty bright but they will be noticeable unless you're clever about hiding them. Wanted to give this 5 stars because the price and performance were great, and I'm not sure if this is a good reason to take off a star, but each color of this glowing PLA filament did require additional tuning of print settings. Perhaps the combination of color and glow in the dark additives just necessitates the extra attention. Either way, it's PLA. They also have glow-in-the-dark PETG, which performs beautifully and may be more suitable if you typically print with PETG.

This PLA is awesome. The prints come out smooth. The quality is great. The glow? WOW! This thing glows (with blacklight charging) like a champion firefly on a hot summer night. I held it under a blacklight for about 10 seconds and was able to capture the image shown in this review. The blacklight and every other light was off. You can actually see my arm illuminated by this bad boy. I was going to give it 4 stars because it does tend to seep a little on the hot extruder and leaves a little bit of stringing, but I am just having too much fun printing awesome glowing Halloween stuff to not give it the glowing review it deserves.

The glow in the dark PLA, which is supposed to be 1.75 is well over 1.78 and will not feed. Quality control is important especially with an abrasive and rough filament like the glow in the dark. It caused a jam and ruined a project. I then got out the calipers and measured it, and it was way out of spec at over 1.78 I guess quality control is a thing of the past. This was a school project my granddaughter was doing. It was disappointing.

If you want unique long lasting glow I. The dark PLA for fun projects - I suggest you buy this roll. Good value for the price - I’m pretty sure that I was able to purchase this item when it was a bit cheaper, as Amazon prices fluctuate. Color quality was a win. Make sure you adjust the temperature settings for best functionality during your 3D printing. Slightly transparent- more opaque - as it looks like an off white filament. It glows for hours though. You’ll be excited to use this PLA on your next prints!
