Kingroon PETG 3D Printer Filament, 10 Rolls, Dimensional Accuracy +/- 0.03 mm, 10kg Spool(22lbs), 1.75 mm, Black

I was looking for some cheap prototyping filament to reduce costs during print testing and refining issues related to form and fitment of 3D designs inherent in the CAD designing process, and wasn't concerned about color, or type for that matter, and at about $10 USD/ Kg I went for this stuff, as the PLA I was using ranged anywhere from $15 to $30 /Kg, but man did I get more than a bargained for! When it arrived, I dried a roll, did my standard calibration like I do on any filament and set up a filament profile for it, from the first calibration print even with the generic PETG profile I already noticed it started out better than most, but after dialing in the settings, this stuff prints absolutely amazing! I have used about four rolls so far, and the consistency between rolls is top-notch, and so far I have zero stringing or clogging (in fact the only print failures I have had have been traced to the files on a few I have rushed through the design process and missed a couple of gaps in the geometry causing a bad mesh, I have had zero filament related failures). And as a surprising result from PETG this stuff sticks to the bed, and remains in place the entire print, but releases cleanly and easily upon completion, all with no glue or other adhesion modifiers to worry about, which combats the main issues I have had with other brands of PETG (some brands would have poor adhesion and come loose from the bed mid print without glue, or others would tear up the bed or leave fragments almost embedded in the plate that were nearly impossible to remove if you didn't use glue), I had long sense accepted that this was just a caveat of using PETG, but so far this product seems to retain the strength and rigidity of PETG, while having the ease of use and versatility exceeding that of standard PLA at a lower price point. I just ordered more, and what I originally intended to be a cheap solution for prototyping or test prints, is quickly becoming my primary filament for quality finalized prints with little to no post-print processing.

these filaments print very nicely with no special settings. Layer adhesion is solid, and the layer lines are pretty much on par with any other good quality filament. The colors are bright and clean. I ran them through an Anycubic Kobra3 V2 and they all printed perfectly on the first run.

Prints fine, no issues.

I’m very impressed with this kingroon Petg. The first things I noticed upon opening the package were the nice plastic spool and the neat winding. Nice job kingroon! I usually preemptively dry all my Petg before even attempting to print with it because I live in a humid climate. I didn’t this time because I wanted to see how good this filament can be right out of the package. Well, it’s definitely good! The only problem I noticed was some oozing coming out of the nozzle when the print head sits idle and warmed up. This is to be expected with undried petg in my experience. Not taking any points off for this. The first thing I did was calibrate the pressure advance and flow rate. Then I sent a benchy over to the printer for a good test. It turned out really well! The overhangs are nearly perfect And there is almost no stringing at all. I would almost say it printed better than the other big name Petg filament makers I normally use. I’m probably going to be making a switch to kingroon for my Petg prints after this great first impression. The color of this red seems like a perfect fire engine red. It’s not a bright red but it’s not a dark dull red either. At this price point, if every spool of petg is this nice, you honestly can’t beat it. If you’re weary of the brand name kingroon because it’s not a big name like eSun or Polymaker and it’s cheaper than them, don’t fret! Buy a spool and try it out for yourself. 100% worth it.

Bought 10 rolls of this PETG. Some prints look fine, others come out like a stringy mess (see photo). Tried drying it—made it worse. Filament became brittle and started snapping. Unreturnable and no way to contact the company. Huge mistake buying in bulk. Avoid.

Arrived in excellent condition, The packaging is clean and very good. I bought it in condition of used-new.

Color not consistent across same product order, one order was a much different white. Be aware when using multiple rolls for "same" color.

I recently made the shift from a resin printer to the Bambu P1S, and after running out of the sample PLA, I grabbed this Kingroon PETG 10-roll bundle to experiment. I couldn't be happier with how it's performed. Prints have been flawless right out of the box all year, using just the default generic PETG profile. The only hiccup was user error was me letting the AMS humidity hit 30%, which caused stringing. I simply dried the filament and refreshed my desiccant, and it was back to flawless instantly. Price and performance are truly hard to beat for this bundle. Plus, customer service was responsive when I asked about food safety and got a reply in just a few hours. Now if only I could stop running out of filament so fast! Highly recommended for anyone wanting reliable, great-value PETG.

Good filament but PETG just isn’t a great material. Not buying that again. I don’t know why but it’s hard to print well

Absolutely zero complaints about this filament. I ordering often. Could use some more exotic colours

Awesome bright colors. No tangles. Great print quality. Great budget Petg

Nicely wound, and easy to print right out of the package. Only 1 of them required drying beforehand.

Prints well and arrived dry.
