  • ⭐⭐⭐⭐⭐ Great Bang for the Buck – Beautiful Rainbow Prints the buck
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. ... show more

  • Nice filament that meets expectations.
Color: Light Chestnut Brown Material Type: High Speed Marble PLA
The filament is loaded on a nice sturdy spool. It printed extremely well using the default PLA setting in my Elegoo Centauri Carbon. Bed adhesion is a bit less than you'd expect from a normal PLA but didn't cause any problems. I had to adjust my Z Seam to reduce the visibility of it but made no other changes. SUNLU is usually very good value for the price and this was no exception. When I need marble PLA again I'll buy SUNLU ... show more

  • SUNLU filament great value, great price.
Color: 1kg*4 Rainbow Regular-01+02+03+04 Material Type: Polylactic Acid
Great filament, good adhesion (I did need to use 60 bed temperature for my Creality k2 plus). The final prints are very good looking and the colors are vibrant and the prints are strong. This is great quality pla for a great price in this condo pack. Also of note is the reusable spool that can “slide on” more pla after you empty one. I love this feature. ... show more

  • Pretty good quality, but may require a little bit of tuning.
Color: 1kg*4 Glow in the Dark Bundle Material Type: Polylactic Acid
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. ... show more

  • Brightest and longest lasting
Color: Glow in the Dark - White to Glow Green Material Type: Polylactic Acid
A little difficult to print. You really need to adjust the z level perfectly. The results are astonishing even 6 hours later you can still see faintly. Don't try to print with regular brass because it will erode it with just one print

  • Favorite Glow-In-The-Dark PLA & Good value for the cost
Color: Glow in the Dark - White to Glow Green Material Type: Polylactic Acid
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! ... show more
