Excellent Quality Filament With Beautiful Natural Colors!
All four colors—Beige, Coffee Brown, Olive Green, and Oak—have a gorgeous, natural look that’s perfect for prints with organic or wood-inspired designs. The finish is clean and consistent, and each spool feeds smoothly without tangles.What really stands out is the print quality. Layer lines are minimal, adhesion is reliable, and the filament handles both detailed models and larger prints with zero issues. I’ve had no stringing or nozzle clogging, and the PLA+ strength is noticeably better than standard PLA.

Sunlu
I’ve been using Sunlu PLA filament refills for several months, and they’ve become one of my go-to options for everyday printing. The quality is consistently excellent — the filament feeds smoothly without tangling or clogging, and the prints come out with a clean, even finish every time.I also love the eco-friendly concept of the refill spools. It cuts down on waste and saves space compared to full plastic spools. The packaging is neat, moisture-proof, and easy to store.The color quality is vibrant, layer adhesion is solid, and I rarely need to adjust print settings. For the price and quality, it’s hard to beat.

Great filament – need a spool
Great product and performs as expected with consistent results. It does not fit on the SUNLU spools that usually come with their regular filaments, as the cardboard tube is too wide. I printed a few other spools that were able to fit this filament properly. All colors appear as described while beige looks like a lighter salmon color.

Inconsistent, Waste of Money and Time
Inconsistent thicknesses with weird deformations, clogging causing errors, waste of time and money.I bought several of these packs and have nothing but problems.To start, the rolls don’t fit on what should be Gen 3 spools like Sunlu claims. Ive compared my spools with their Gen 3 and they are the same.This filament is almost oily or slimy in its feel and print, when it prints properly. The consistency seems to change within the spools even with proper drying techniques resulting in print anomolies. And now, the white has clogged my printer 3 times in the middle of multi hour prints requiring me to disassemble the extruder to clear the clog, and yes, I’ve troubleshot with the manufacturer and other filaments print without these issues after being calibrated.Unless Sunlu can do better, DO NOT PURCHASE!*Update*After trying to reach out to SUNLU, I’ve been left with only crickets. They are completely unresponsive and I’ve now had a spool basically disintegrate going through the tubes, leaving residue throughout the entire system. Never had a problem with SUNLU before but now they don’t seem to care. 20 spools going in the trash now because I can’t trust any of them.

Amazing products
Staying away from white. It is to unpredictable. The last 4 pack of refill i got. 2 rolls printed fine, the other 2 i was only able to use maybe 3/4 of one roll and just opened the other and its having the same issue even with it being dry. plan on trying a grey and probably just move to their black. other then this last roll their filament is great and i do plan to stick to the company unless i have more issues.

Good value
Pretty good filament at a decent price. Plus, no plastic spool. Win-win.
