Kingroon High Speed PETG 3D Printer Filament 1.75mm, 3D Printer Rapid Filament for 300-350 mm/s Hyper Printing Filament, Dimensional Accuracy +/- 0.03 mm, 10 kg Plastic Spool (2.2lbs）（Mixed Colors）

I've noticed some of the brands are paying less attention to quality and there are inconstancies in width and bubbles in the filament and those cause failed prints halfway and I was going crazy trying to fix it at the printer and finally realized it's the filament causing sudden issues halfway through the print. Some also cause excess stringing and some actually stick together in the roll already and don't detach as printer pulls them. Funny thing is that these issues mostly didn't exist 2 years ago when I started but I see them more often now as everyone is trying to make their filaments cheaper.After many back to back prints I'm glad that this company is producing good quality filaments , actually better than last year, with none of those issues. The pink one I used created beautiful prints and actually I was able to print with no brims and it stuck to the best very easy and when finished it popped off with a tiny touch of the blade, even though the lizard had lots of small tiny pieces and fingers, it adhered well to the plate.Update: I just printed a new lizard and looks even better, no stringing issue.

Overall, I'm thoroughly impressed with the Kingroon High Speed PETG Filament and would highly recommend it to anyone looking for a reliable and high-performance 3D printing material. I've also noticed that this filament is less prone to warping and bed adhesion issues, making it a breeze to work with. The layer adhesion is excellent, and the print quality is smooth and detailed.

Product arrived pretty quick and the price was excellent. I've only run one test print so far (ohh there's plenty to come) at 300mm/s on an ender 5 pro with sonic pad. I needed a bed mount for the nebula camera so...1st print. Obviously I still need to play with settings to dial in the optimum settings, had some blobbing, stringing and such but that was more or less "out of the box" 300mm/s, 235°c hot end, 75°c bed (in the recommended range) 4mm retraction @45mm/ and some other basic "common" settings. I've still plenty of testing to do...one setting at a time. And once I dial it in I think it'll be golden. Fyi, the bed mount print is functionally perfect, just not super pretty.

I print this on my X1C and it does great. I am using the Bambu PETG HF profile and it has worked great so far. I am using this in the AMS as well. I have only printed a few big strong parts but they have worked very well. These are parts that set out in the sun and so far they have done fine. I will definitely be buying this product in the future.

I got the orange color and I'm printing Lego gears and these e dead up being super strong, cannot bend or break with your hand. I also like how they mesh so perfectly with my other original orange Lego pieces. No stringing at all and filament doesn't get stuck in the feeder nor it sticks together in the roll like some others do. I like this.
