    5.0 out of 5 stars Great color and print quality
    Reviewed in the United States on January 10, 2025
    So far my use of this filament has been limited to a relatively small portion of a multicolor print, but it performed flawlessly and was the perfect color. One minor complaint would be that the spool didn't seem to live up to the claimed temperature rating and actually warped in my dryer.

    At first, it was very stringy, but after drying overnight it prints flawlessly on my X1c using the Bambu PETG Transparent preset. Great stuff and good value!

    i just got into 3D printing a few months ago. i bought the factory filaments not knowing this manufacture made great products. on a suggestion from a friend i bought a roll of the PETG gray, after verifing it was dry, came out of the bag @ 20%RH. which is in the suggested range. i started printing some storage boxes. the filament was wound perfectly w/o any crossings or snags. it printed flawless with default printer settings. i have since ordered every color in the PETG line. the rolls come as 2 disconnecting twistloc and the company has verified they are going to release refill filament so to generate less waste of old rolls.. yeay..

    4.0 out of 5 stars Not good for Bambu Lab's AMS and AMS Lite
    Reviewed in the United States on March 28, 2024
    I've been through about 400 rolls of PETG so far. Here are the good, the bad, and the worst from my experience. Worst is for Bambu Lab AMS and AMS Lite system. So read on.
    I have a small print farm with 7 printers currently. 2x Bambu Lab P1S with AMS, one X1C with AMS, 4x Bambu Lab A1 Combo with AMS Lite. AMS is a must have item for me. It saves so much time and hassle.

    The good:
    -Price is very good especially when you find it on sale.
    -Prints pretty well. I like the sheen too. I print with 0.6mm nozzle at 245C. Only had some batches with layer adhesion issue when I tried to print 20 of the same model at once. Maybe just a little too much time in between layers.
    -It's in stock most of the time. Of course when I find it in stock, here or their website, I buy 200 rolls at once.

    The bad:
    -Many of the last 190 rolls I ordered seem to be dirtier than the first 200 rolls. You can visiblely see the dust/debris on the roll right after opening the vacuum sealed bag. It gunk up the extruder gear and falls on the print plate and inside the AMS enclosure for the extruder gear. It's really hard to clean it off. Compressed air doesn't really get all the gunk and just blows around inside the extruder gear enclosure for the AMS and AMS Lite.
    -It's spooled tightly just like Sunlu claims. The bad part is that it messes with the AMS. The printer would throw an error message and stops the print. If I just hit retry, it will just continue to work without me even touching anything else. I finally found a solution on Bambu Lab A1 AMS Lite, turning off the "Filament tangle detect" under Print Options. (Hope this helps someone with similar issues) Unfortunately I haven't found a solution for my 2 P1S combo and X1C yet. Some of you may say it's the printer, not the filament. I didn't have any issue with eSun or Inland filament.

    The worst:
    -This is the one thing I hate the most and there's absolutely no solution unless Sunlu changes their filament reel hub style and how they start to spool the filament. The center of the spool is smooth with a little hole where the filament starts on the spool. To get it "hooked" on the spool, Sunlu "bends" the tip of the filament to get it to stay. This little bit of a bend is causing it to jam inside the extruder gear in the AMS. So many times I had to disconnect the PTFE tube to clear it out. It's a big pain in you know where for the P1S and X1C AMS system. It's really hard to pull it out too even after disconnecting the PTFE tube from the back. See attached picture for the "bend/kink" at the end of the spool. This defeats the whole purpose of having the AMS to automatically switch to the next roll. This might be the one and only factor that will drive me to a different brand all together. Inland doesn't have this issue. Its spool hub has hollow areas where the start of the filament is simply through a hole, without a "hook". When it gets to the end of the roll, it just pulls right out without any issue. I wish Sunlu would consider improving how they start the spool so there's no bend/kink.

    Prints well, and good layer adhesion.
    My only concern is the continued availability of specific colors. Many of the colors listed aren't shown anywhere on sunlu's website, so not sure if these are discontinued backstock or what. Heck, not even sure this seller is official sunlu.

    1.0 out of 5 stars Tested multiple rolls - Very likely NOT PETG as advertised
    Reviewed in the United States on April 30, 2022
    Tl;dr: This stuff is junk and borders on fraud. I print exclusively in PETG for my shop and am confident this material isn't what SUNLU claims. Failed my heat at 150F (65C) warping under its own weight, prints like crap and is extremely brittle, and is the only spool I've had fuse together in a filament dehydrator at 65C. Probably not just a bad batch either based on experience a separate order. DO NOT buy this material.

    In addition to this one spool I purchased off of Amazon, I recently ordered 10 rolls of PETG directly from the manufacturer under their sub-brand, JAYO, and I can confidently say this stuff is either 1) NOT PETG as the claim and actually PLA or 2) PETG that has been mixed with poor additives which have compromised its material properties. The only reason I made this separate purchase was to confirm my findings from the bulk order, and despite having different brand names the spools and labels are completely identical. No doubt they come from the same manufacturer.

    Context: I print items for my shop that I need to be reliably heat-safe since they are often used to support computer hardware in warm environments. Normal PETG offers the perfect balance of heat resistance, consistent print quality, and minimal fuss. This SUNLU material (I won't even call it PETG) offers NONE of that.

    Printing at 230C on a reliable Prusa MK3S, this stuff is ridiculously stringy. It’s almost like if you tried to print PLA with the nozzle temp way too high (hmmm…. Interesting). My first thought was the spool had just been packaged in a humid warehouse and needed to be dehydrated (and cynical me assumed this was intentional to help sell their filament dehydrators). No problem, I’ll just put it in my usual PETG dehydrators for 8 hours at 150F (65C), and- oh… the spool has almost completely fused together!! To be clear, I use my dehydrator on dozens of PETG spools each month, sometimes up to 24 hours, and I’ve never had a PETG spool do this. The filaments began making a peeling sound as it’s unwound from the spool and broke 3 times trying to print with it.

    I then took the one successful, albeit extremely stringy/globby, print (from before dehydrating the spool) and tested it to another made with the same gcode using my usual PETG supply. After 20 minutes of hanging from the shelf of my dehydrator oven at 150F (65C), the SUNLU bracket completely warped under its own weight. I am so glad I checked because this could have caused a serious hardware failure for one of my customers had I just cleaned up the stinging and sold it as-is. After the print cooled I then removed it and just tried to break it in my hands and the piece snapped violently, through small plastic shrapnel in all directions. Normally, most PETG prints fail in a more “flexible” way- stretching and lightening in color under stress rather than shattering… like PLA.

    Finally, SULU’s documentation for their PETG is kinda all over the place. From the paper inserts with each spool to what’s printed on the box to the documentation on their website, you’ll find conflicting guidance. They acknowledge that it should be heat-resistant up to 180F (~80C) but also recommend printing it as low as 200C – the same as PLA… For reference, I normally print PETG at 240C with a 90C bed on my MK3S with fantastic results.

    I really wanted to give SUNLU the benefit of the doubt that I had just received a few bad spools in bulk, but after testing this spool from Amazon from a completely different manufacturing date I see that they are just selling extremely poor-quality material. To their credit, after much (frustrating) back and forth with their customer service team, I received a refund for the bulk order, and I will be returning this spool to Amazon ASAP as the material clearly isn’t what it’s advertised to be. Were I a novice printer and this were my first experience with PETG I’d be completely turned off by it.

    If anyone at SUNLU happens to see this: please do better. Y’all are too big in this space to be so careless.

    Prints come out great after dialing in the settings on a Bambu P1S, no stringing. Print temperature used was 225C, bed temp of 70C. Retraction speed bumped up to 40mm/s. Printing almost all features so slowly at 100mm/s. Volumetric speed set to 9mm^3/s. Dried for 10 hours before printing
