SUNLU PETG Filament 1.75mm,2kg,Black+White

This was the first spool I bought for my ender 5 pro, never 3D printed before. Had all kinds of issues until I dried the spool on the bed at 60 deg C for 12 hrs, and had a dehumidifier in the basement (ambient humidity was 60+ until I did that). Down to 40ish % humidity in the room now. After those changes, ran a temp tower, ended up at 235 for print, 245 for first layer, checked my retraction using two parallel towers, ended up at 5mm retraction, might go a little lower. Got rid of all my stringing. Drying the filament and managing humidity, and lowering nozzle temps to 235 got rid of my goops on my walls. Also, drying the filament made most of the temp tower actually look pretty decent, so it's more forgiving if you have dry filament! Overall, this is a reasonable product, it does run hotter than other PetG, I understand. Final settings: first layer: bed at 90, nozzle at 245. After that: bed at 85, nozzle at 235. Cooling off for first layer. Using a magnetic pei bed. Clean with isopropyl alcohol before running. Sticks great at those temps. Will buy again, especially with the discount when you buy multiple spools. Five stars, unless I learn something new after doing more complicated prints.

I’ve had an excellent experience with SUNLU filament. It prints with a smooth, clean finish and delivers consistently reliable results from start to finish. The filament feeds evenly, layers bond well, and I’ve had minimal issues with stringing or clogs. Whether I’m printing detailed parts or functional pieces, the quality stays uniform throughout the spool. Great value for the price—definitely a filament I’ll continue to use and recommend.

Great value and Great print quality. This PETG filament is a game changer when it comes to printing functional parts. While it can sometimes have issues printing fine details, it excels at making parts that are more durable than PLA. I printed out a small, thick hook and lifted a 30 lb dumbbell with it. The value in this bundle is also amazing and cheaper per spool than a lot of the PLA on here.

I have bought several rolls of this filament it works good.

Sunlu is doing great work. Their new spools work great on my AMS lite with no adapter, and the AMS2. Newer spools also are arriving surprisingly dry. Ive tested several out of the package and it printed great. (Yea I know. I still dry before use.... but if you don't have a dryer. This will probably be fine as is.) Its also very neatly wrapped on the spool.

This is my first experience with PETG and took some trial and error. If you try to print without drying you will get oozing out of the nozzle which can cause it to stick and clump. After drying it on a dehydrator for 6 hours (3 hours on one side, flip over for another 3) the oozing vanished and no more sticking to the nozzle. Also helped quite a bit with stringing. Night and day difference. A lot of people say you have to print at a high temperature, but I found that anything above 255 causes some stringing, although not as bad as it was before drying. Overhang performance also suffers above 255. However, this is with Bambu's Generic PETG profile. I tried OurAngryBadger's profile for Sunlu PETG and it made the stringing far worse, but improved bridging. The sweet spot, at least for white, seems to be 240-245 with 250 being acceptable with slightly worse bridging. It kind of makes sene though because Sunlu lists the range to be 223-260 between low speed and high speed, making 240-245 right in the middle. I'm using a Cosori food dehydrator and some printed extension walls. If you don't have dry PETG, I highly recommend using a 5 gallon bucket or print the extension walls 1 at a time to minimize stinging so you can later use the walls for drying.

I have used a literal ton of Sunlu filament. I have rarely had any issues with it. It just works and prints great.

Sunlu has recently become my goto for filament, the quality is great, the packaging is great, and I especially like their new spool design. All at a great price for PETG with the rolls going on sale often or outright being cheaper to buy in bulk

El producto es de buena calidad solo, que el paquete de dos rollos de filamento PETG blanco y negro, llegó con un rollo de PLA blanco y un rollo de PETG Negro. El resto de los detalles de empaque llegó correctamente

El producto llegó mixto, PETG en negro y PLA en blanco cuando debió ser PETG LOS 2

No va ni la mitad del rollo y ya han aparecido 2 enredos, lo cual hace que se desperdicie filamento, se arruina la figura y se pierde tiempo. Decepción de producto
