Color: Black+white+red+klein Blue
Material Type: Filament 4KG PETG
Great strength after printing, requires some tweaking to get print parameters dialed in. No tangles, easily mounted on spools as a refill. I tried to do single-color prints as much as possible; my AMS Lite would sometimes struggle to feed at the required rate to keep up with the print head, leading to stuck filament errors and purges. Printing on the external spool eliminated this problem. Has a relatively glossy/shiny appearance, which seems to be expected with many PETG filaments, in my limited experience. I kept losing prints off the bed because the nozzle bumped or caught on seams and edges. Printing with a Bambu A1 with AMS Lite. I found that this SUNLU PETG filament prints best at ~260°C nozzle temp and 65°C bed temp. I also bumped the Z-hop up to about .5-.6mm, to limit unwanted contact at the workpiece between the layers and nozzle during crossovers. Now that I have used most of the 4 kgs, I feel comfortable with it, but I have to admit it was quite frustrating at first, throwing away partial prints and losing time on the printer.

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.

Material Type: Filament 4KG PETG
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.

Best bang-for-your-buck Prime-shippable PETG! Honestly really grateful that SUNLU offers PETG refills that fit on Bambu reusable spools and also closely match the appearance of Bambu filaments. I've had no issue using the clear/transparent, black, and gray filaments in lieu of the Bambu equivalents, even if swapping mid-print. I tried really hard to find any sort of difference, but they were just as strong and looked just as good. I think the white color included in this bundle is actually better than the Bambu PETG white filament, but this may be due to the nature of the prints or the age of the white filament I had on hand. Either way, no complaints. I'm not sure if SUNLU PETG is the same as Bambu PETG but in this case they're functionally identical and both work great. Other PETG brands are often more difficult or finicky to print than PLA, but this stuff works great!
