​​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).

This SUNLU PETG bundle has been a great addition to my filament collection. Getting four full spools (white, cyan, magenta, and yellow) in one pack is a really nice value, especially if you do a mix of functional and decorative prints. All four spools came individually vacuum sealed and were in good condition when they arrived. The filament was wound neatly, which helped it feed smoothly during printing. I’ve already gone through several prints with the white and cyan spools and didn’t experience any tangling or clogging. The print quality has been very good for PETG. Layer adhesion is strong and the parts come out durable with a nice, clean finish. With a little tuning to my usual PETG settings, the prints came out consistent with minimal stringing. The colors are also bright and look great once printed. Another thing I like is that the spools work well with AMS systems as well as standard FDM setups, which makes them pretty versatile depending on your printer setup. Overall, this bundle is a solid choice if you’re looking to stock up on PETG with some useful colors. Good print quality, reliable filament, and a good value for four spools. I’d definitely buy this bundle again.

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

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.

Decent glow, a little hard to get to stick (used cool plate, texture plate, needed up have to glue down) printed well for the project, though. Seemed to fit my AMS just fine and no notable issues with diameter deviation.

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.

This PETG High Speed filament is excellent, and printing on a industrial/aerospace/automotive/medical type of 3D printer such as my Raise3D Pro3 Plus large format 3D printer, I am able to print out well design prototype prints..Fast Delivery-Good Price Point..

packaged very well, All spools were still vacuum sealed. very nice filament to print with. I get great adhesion and bonding with minimal stringing after being well dried. And they have reusable spools are fantastic

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!
