Color: 4000g Petg Black+black+black+black
Material Type: Filament 4KG PETG
I've been using this SUNLU PETG refill filament on my Bambu Lab P1S and it's been performing excellently. The refill system works seamlessly with the Bambu Lab ecosystem - the spool winding is consistent and feeds smoothly without tangles or snags. Print quality has been outstanding. Layer adhesion is strong, and I'm getting clean, consistent prints with minimal stringing when using the standard PETG profile. The material has good temperature consistency throughout the spool, which is critical for dimensional accuracy on longer prints. The price point makes this an economical choice compared to buying new spools each time, and the refill approach is more environmentally friendly. I've printed functional parts, mechanical components, and prototypes with this filament and it handles everything well. For Bambu Lab users specifically, the refill design integrates perfectly with the AMS system. The filament characteristics match well with the built-in PETG presets, making it essentially plug-and-play. Highly recommend for anyone running a Bambu Lab printer who wants reliable PETG at a good value.

Sunlu has never let me down. It is great filament at a good cost. Print quality is excellent. It sticks to print beds that are properly maintained. I also like the color consistency between spools.

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.

Great basic PLA. No tangling or clogging. The gray color is great for models and I prints nice and smooth.

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.

I mostly print functional items for tool storage or other things, so I don’t need pretty colors. What is great about this filament is that it comes on refill spools that fit on Bambu reels. I was tired of tossing plastic reels. I was looking for a price conscious option that printed well and was readily available. I have had minimal stringing on the things I have been printing and am very pleased with the strength of the items. I’ve bought the Sunlu PETG in a variety of colors. I find it to be a bit more gloss finish than Bambu or Creality filaments, but for my use cases this doesn’t bother me.
