"Best Priced PETG of All Time" For the price, this is most likely the best priced overall filament of all time. The quality is AMAZING, no bubbles, no nothing, the print is crazy great. The Adhesion is great, and the texture is also good. I have never had it clog on me because of how easy it is to use! This is the greatest PETG I have ever tried. Would 100% recommend as a first filament because of its strength and ease of printing! Super great

printed on a p1s: Most of my prints are with sunlu filament its the best value. I have the abs, pla, and petg its the best value in every type of filament it just works and works good. I really like this semi transparent bundle the color looks really neat it might be my new favorite petg it gives it a sorta crystalized look seems to be just as good as the regular petg. I print mostly functional parts and not so much figurines or props but I occasionally print high quality and sunlu still does it. The value cant be beat!

Prints great if not a little too glossy. Is kind of an oil black look. Printed a dementor statue from it and it gave the statue a misty look to it like it maybe wasn't quite solid. But the glossiness of it definitely makes it look like cheap plastic. Maybe some sort of clear matte finish would dull the gloss. This is not a dark black.

These come wet. I guess the only brand I checked in the past before drying was Elegoo, and putting it in my dry box after opening it it is around 11 or 12 percent, and I always want it below 10 percent when I use it but this in one of the same dry boxes is around 40 percent. Then one of the spools was broken, and one of the reason I got these was for the reusable spools so I can take filament off cardboard spools to put on my empty Bambu spools but now one is broken, and can't use it in my AMS since the side isn't round anymore. They do weigh 1kg though, almost perfect, I weight one of their empty spools with a empty cardboard center and a desiccant pack/plastic bag from one of these spool, tore the weight, then put a full spool on and it is 999 grams, so 1 gram off. The empty cardboard center I used as from Bambu so that might have thrown it off one gram. By the measuring tool on the side it looks like it should be 800 grams but that might be for PLA. A lot of the reviews say these aren't 1kg but I think they are saying that because it looks like it is only 800 grams by the measuring tool on the spool but that is wrong. I have not printed with them yet. I got these and some spool of another brand but these will be dried and used next. I actually need the yellow right away so that is going in my AMS to dry next. I'll update the review then.

This was my first purchase of filament. I bought a Bambu printer and it came with just a couple of small sample filaments. I wasn't sure if I should order PLA or PETG. I wanted to make durable prints because I mostly make parts or things requiring strength. I have used several different colors. I have them loaded in a multi material loader. None have failed to load or had issues printing. The bags came sealed. I have used some that I dried manually and some straight out of the packaging. There was no noticeable difference in print quality. I would recommend these over the Bambu filaments for the price.

I've gone through like 20kg of this stuff in my bambu a1 mini and have not had a problem. I dry each roll for 16 hours at 65c before using and keep it in a large custom made drybox which keeps it <20% RH. From there it just works, prints well, and I also use the end portions of the rolls in a 3d printing pen for fusing large parts. Couldn't recommend more. The stuff isn't magic but is extremely cost effective and prints well.

Bought this to use in a Bambu P1S and it worked perfectly. No special settings, just load it up and pick SUNLU PETG and print. Great quality, adhesion (without glue), and consistent color.
