​​SUNLU PETG Filament 1.75mm,Strong 3D Printer Filament,Ultra-Low Stringing,Exceptional Layer Adhesion & High Toughness,Dimensional Accuracy +/- 0.02 mm,Fit Most FDM 3D Printers,1kg Spool(Black).

5.0 out of 5 stars Great value PETG bundle — prints beautifully with minimal stringing and strong layers Picked up this SUNLU PETG Filament 1.75mm 4KG Bundle for my Bambu Lab P2S projects, and it’s been fantastic so far. I’ve gone through all of it already! Right out of the vacuum-sealed bags (which were bone-dry—no moisture pops or hissing at all), it feeds smoothly with excellent dimensional consistency. I dialed in 240°C nozzle, 75°C bed, and low fan (20-30%), and the stringing is way less than what I’ve seen from other budget PETG brands—almost none even on bridges and overhangs after minor retraction tweaks. Layer adhesion is superb; parts feel tough, flexible without being brittle, and they handle impacts well . No warping or delamination issues, even on larger prints. The colors are consistent spool to spool! For the price on 4kg total, this is unbeatable value. Way better than pricier brands I’ve tried for everyday printing, and the spools are neatly wound with no tangles. If you’re looking for reliable, low-hassle PETG in bulk that performs great, grab this bundle—you won’t be disappointed. Already planning to reorder more!

Overall, the Sunlu PETG filament is a dependable, high-quality product that delivers consistent, professional results. I highly recommend it for anyone needing strong, reliable 3D prints! Amazing Layer Adhesion, Smooth & Consistent Printing, Great Finish and Dimensional Accuracy

Sunlu makes good filament and generally has a good price. It prints well. I also have the Sunlu filament dryer and does a great job.

UPDATE: Sun Feb 22: First print straight out of the package, did not dry filament. No post processing: what a great filament. Printed on Prus CoreOne with generic PetG profile and variable layer height. The Sun doesn't lie, however. The color of green is grayed, chalky, and not like the advertisement at all. This is not about my monitor. This is not the rich deep green Sunlu advertises. If Sunlu fixed their advertising images it would be great. There is a place in the world for the green they are selling. It would just be nice for the consumer to know what they are getting ahead of time. Moving my rating up from 3 to five, because at this price and quality, I can afford to experiment, now that I am aware the colors may be off. Will update again and post good pictures of the colors as I find them.

WARNING for Anycubic ACE users: The filament is rougher to the touch, almost feels like CF. Anyway, whatever it is doesn't work well with the Anycubic ACE. It didn't like sliding through the tubey tubes and made the ACE grunt like he was sittin on the terlet after eating a wheel of cheese. No issues printing, it was just issues when trying to change colors. The filiment did not want to go. I had to remove the 4 way thingy at the head and straighten out the PTFE tube a little so it would slide out. It had some grippy grip. The color was good. I did thick and thin prints. It glows a white/yellowish color. Not crazy, but fun, when its not wrecking your shiz.

I’ve lost count of how much SUNLU PETG I’ve bought. It’s been very consistent and reliable for my 3D printing projects with good layer adhesion and print quality. I do live in Utah where it’s dry, which probably helps, but I’ve had great results with this filament. It performs right up there with Bambu Lab filaments for me, and I’ll keep buying it.

I have had nothing but great prints. I put this up against a print I did with another popular brand PETG, and the Sunlu was so much more smooth, not showing the layer lines. I am using this on a Prusa Core One with a diamondback nozzle, printing on the lower part of the temperature spectrum (due to diamond back nozzle having highest heat transfer efficiency).

Printed fantastic, no issues. Diameter checked in various places, all within tolerance. The gen 3 spool is a great improvement over the original spools. Buy, dry and use. No fuss.

je suis très satisfait du résulta pour faire de petite pièce, le rendu est correcte.

Valeur sûre en filament. Très bien enroulé, s'imprime facilement. Rien à dire.

C'est un bon produit. Toutefois, il est sensible aux paramètres et aux types d'imprimantes. Je recommande si vous savez faire.

Très bonne qualité, pas de souci d'impression.

Bonne marque et bon produit!
