CREALITY PETG Filament 1.75mm 3D Printer Filament, 1kg (2.2lb) Neatly Wound Spool, Dimensional Accuracy ±0.03mm, Fit for Ender, Bambu Lab, Anycubic,ELEGOO FDM Printers, Black

While these Creality PETG refills aren't natively recognized by the Bambu A1 mini since they lack the proprietary RFID tags, they offer a high-performance, cost-effective alternative once you manually toggle the "Generic PETG" profile on the printer’s interface. The filament quality is remarkably consistent, but to maximize the A1 mini’s high-speed capabilities, I’d suggest performing a manual flow-rate calibration—the transparent roll, in particular, benefits from a slightly higher nozzle temp of 250°C to maintain structural clarity. As long as you don't cut the binding straps until the refill is fully seated on a Bambu master spool, the winding is reliable enough to handle the A1 mini’s rapid retractions without tangling. I also used these using the AMS system for Bambu and they all worked perfectly fine. I upped the plate temperature slightly for better adhesion.

This PETG filament works exactly as advertised and fits perfectly on a Bambu spool. No issues at all loading it—just like using a regular Bambu refill. I added it as a custom filament in Bambu Studio, followed the recommended settings, and had zero printing problems. The prints come out clean with a nice shiny finish. It’s also much cheaper than buying directly from Bambu, which makes it an excellent value. I always dry my filament, and if I start to notice any stringing, I just pop it in the dryer at 60°C for 2 hours and it’s good as new. Pros: • Fits Bambu spool perfectly, no issues loading • Prints clean with a shiny finish • Much cheaper than Bambu-branded filament • Easy to set up as a custom filament in Bambu Studio • Responds well to drying when needed Cons: • None so far Definitely my go-to PETG from now on. Thanks, Creality!

The CREALITY 250g PETG Filament Bundle has been a great way to test multiple colors without committing to full spools. The quality is surprisingly good; filament diameter is consistent, and it extrudes evenly with no clogs or bubbles. It’s very easy to use, even for PETG. I didn’t need extreme temperature tuning to get clean layers, and the bed adhesion is excellent; parts stick firmly during printing but release easily once cooled. There’s no brittleness to speak of; the strands bend slightly before breaking, which makes it much easier to load and handle than some off-brand PETG I’ve tried. The fit and flexibility of printed parts are both impressive; tight tolerances hold true, and the final prints feel durable with just enough give. Overall, it’s a high-quality, beginner-friendly bundle that delivers reliable prints and great value for experimenting with PETG colors. I’ll definitely order it again.

If you’ve ever wrestled with stubborn PETG that strings like crazy or clogs like it’s auditioning to be a plumber, this is the filament you’ve been waiting for. Creality’s PETG in blue is a game changer. First off, the spool is neatly wound, which seems like a small thing until you’ve spent 20 minutes untangling a bird’s nest of filament at 2 a.m. (Don’t ask how I know.) It’s a joy to work with right out of the box, and the dimensional accuracy is on point at ±0.03mm. That’s not marketing fluff—it’s actually consistent. This filament plays nice with printers like my Ender 3 Pro and ELEGOO Neptune, sticking perfectly to the bed without needing to drown it in adhesive sprays. I printed a phone holder and a mini-diorama, and the layer adhesion is chef’s kiss. Plus, PETG’s trademark toughness shines here. These prints aren’t just pretty; they’re sturdy enough to survive my 6-year-old’s “stress tests” (a.k.a. unprovoked attacks). The blue color is vibrant but not obnoxiously so—it has a sleek, professional vibe, like it knows it’s better than the competition but doesn’t need to rub it in your face. Cons? Honestly, I’ve got none, except now I feel bad for all the other PETG sitting in my filament stash. Guess I’ll be “accidentally” printing blue everything for a while. Final Verdict: If you’re new to PETG or tired of mediocre brands, grab this spool. It’s the filament equivalent of that reliable friend who never flakes and always brings snacks.

When it prints it prints well. Used the mid point of the temperature settings on label and worked well. Prints came out very beautiful and strong as well. However I did some 6 hour prints over night and in the morning print "completed" without filament so that only a certain height was printed. Investigated and found the filament goes into the hot end but didnt extrude. When I retract i notice the diameter is larger. One would assume the hot end may have caused the filament to expand but I had similar experience on first prints ie nothing printed as yet and also in color switching so that other filament is further down the hot end and this filament sits on top with a slight gap; and even once it pushed through without going through the hot end (because of diameter) but pushed outwards causing hot end to shift a bit for the filament to otherwise exit. Luckily caught it when it did that to correct. So in about a third of the roll it had these issues maybe 3 or 4 times and when I caught it I would try to fix it but sometimes for the overnight prints I couldn't fix it and i therefore had wastage of filament for the part that printed. The inconsistency is for a short length but I cut about 2 to 3 feet and then try again. I have used on flashforge ad5x (mostly one color but sometimes multi color) and anycubic kobra s3 (single color only no ace box) I like the final look and quality but the caveat is whether or not the print will be successful due to the filament diameter I mentioned. Maybe I got a bad batch I dont know.

Once you dial in the PETG settings Creality has been near flawless with .6mm nozzle. I've through 4 spools, and have another 9 ready to go.

I’ve had an awesome experience with Creality’s PETG filament. Prints come out clean with strong layer adhesion and a smooth finish — perfect for functional parts. It feeds consistently with no clogging or stringing issues once dialed in. Color is vibrant and the spool is wound neatly, which definitely helps prevent tangles. I also appreciate that it’s less brittle than some PETG brands I’ve tried. It sticks well to the bed (I use 70–80°C on the build plate) and has very minimal warping. Overall, great value for the quality — it’s become one of my go-to filaments for durable prints!

Prints flawlessly. I've used egloo for years. I think I'm going to switch.

No sigas las recomendaciones que viene en el paquete, yo recomiendo usar la cama a 60 grados y la temperatura del extrusor en 215 a 220grados, si le pones a 70grados la mesa y a 230 a 260 como indican las instrucciones se van a quemar tus piezas (esto aplica para mi Ender 3 v2). Es un excelente material para trabajar y muy resistente, además siento que no se consume tanto como los demás. Para mi excelente producto.

Creality PETG is my default choice, as I run a small print farm, and it produces very consistent results across several printers, at 245°C. It’s worth the money. For the lack of hassle. It’s bright red, as opposed to some washed out salmon coloured ones I’ve regrettably purchased.

Worked as expected!

Very good filament. Definitely recommend. Didn’t even have to dry this

Not very good. Maybe with a bunch of testing i might find a way to get this working but even with lots of drying it shrinks / deforms badly off the bed and prints fail. I use a lot of petg with my printer and it’s usually very good, but this filament is difficult. ..I’ll probably figure it out but it’s pain.
