- 2SUNLU Refill Filament- SUNLU PLA Refill filament is reliable, versatile, and easy to use. No clogs, bubbles, or tangles, its excellent layer adhesion ensures high-quality prints every time.

Excellent PETG from Sunlu. Zero printing issues on the P1S. Great surface quality and strength. I specifically bought the bundle with pastel, unusual colors because I was tired of the standard RGB palette, and they are excellent. Pale green and coffee brown are my favorites. The refill rolls fit perfectly on standard Bambu Lab spools without any problems. I will definitely keep buying it and plan to try the other colors. Recommended.

Good quality but color is not well represented in their product photos. I ordered the purple to make assistive devices for a friend in her favorite color. The Sunlu PETG Purple is closer to a Lilac with a touch of blue – it's lighter and less saturated than product photos. See my review photos here, where you can see it on a calibrated grey card and a calibrated Datacolor Spyder color card. Mechanically it's top quality. Great adhesion, good strength, very little stringing. I'll buy more of their filament! Even this. It's a very nice purple, just not a bright, intense one! :)

Edit: Just ordered new Sunlu spool and the new design is thicker, so adding 2 more star to the review, check fourth image. Original: Does not fit Sunlu spool, literally, the refill spool is too thick to even push the two half remotely together, I can easily close them without the refill-lament but with it I can’t, even when forcing my bodyweight onto it. You can see the thickness of it when pushed into an existing spool, it has to bend outward to accommodate the refill-lament.

I like sunlu products but these spools were wound weird and get stuck so much it’s not even worth the effort and I figured I could fix them so they are used now and can’t return them! This isn’t the first batch of sunlu I’ve gotten that have issues all the way through the spool. They get stuck because they have been over lapped with filament and not wound tight

Does not fit standard Bamboo printer reusable spool. I had to print an adapter for the spool. The adapter makes the spool too wide to stay on the spool holder and it will fall off mid-print. The filament gets caught up when taking filament from the edges against the spool almost guaranteeing that the spool will be pulled off. A complete headache.
