Official Creality CFS Multicolor 3D Printing System - 16 Color Auto-Switch, Anti-Moisture Storage, Upgrade Kit for K1/K1 MAX/K1C/K2/K2 Plus 3D Printers

This offers a reliable and high-quality option for 3D printing enthusiasts. Known for its excellent strength, durability, and chemical resistance, PETG is ideal for both functional prototypes and hobby projects. The filament's consistent diameter ensures smooth extrusion and minimal printing issues, while its vibrant color options add a professional finish to prints.

The filament arrived with a very good vacuum seal and the desiccants were large. I had no issues with printing directly without putting it in a filament dryer first. I printed a map of the city that I live in (Honolulu). Kind of a waste to print using PETG since this is a simple PLA print but I wanted to send a photo of a print with my review. There's some stringing but that's because I got a little speed happy in the slicer settings. I expected it to b I have always had great luck with Comgrow, the few times I've bought their brand. I hope I didn't jinx myself by typing this haha. This is the first PETG spool I've ordered from this brand. No clogging issues, adhesion was perfect. I have a Bambu P1S with a textured plate and I increased the bed temp to 80c degrees to avoid adding a brim. It worked really well! The only thing that sucks is that like everything, this brand has increased its price dramatically. Could be tarrifs but I'm guessing. Not being political. I feel like things from China have increased prices so much and the prices that used to feel like a great deal, now just feel like normal US prices. Filament probably costs pennies on the dollar to produce in China. The one thing about Comgrow is that they seem to have flash sales (or whatever Amazon calls them), often so if you wait a day or two, you'll likely find a window of time with lower prices. It's good filament. Ok I'll shut up now.

As a hobbyist 3D printer enthusiast, I’ve tried various filaments, but Comgrow PETG stands out for its consistency and ease of use. The spool is well-wound with no tangles, and it prints beautifully at standard PETG temps—minimal stringing, excellent layer adhesion, and vibrant colors that pop. It’s moisture-resistant out of the box, reducing those pesky bubbles, and the strength of the finished parts is impressive for functional prints like enclosures or tools. Great value for the price, and it works flawlessly on my Ender 3. Five stars—Comgrow has earned a permanent spot in my filament arsenal!

I purchased 8 rolls of the Comgrow PETG and have gone through 6 of them now. I am working on a large model and I use the PETG for the model and also for the tree supports. The filament works great now that I have all the settings dialed in. At first I had the flow set at 0.8 because that's what the flow calibration test concluded it should be. But I was getting blobs, layer separation, stringing, and model failure. After second-guessing myself on everything from Temps to enclosure vs non-enclosure, cooling fans etc, I decided to reset the flow to 100%. Huge change, and now it prints great and leaves a nice smooth, shiny surface. I print this filament at 245C with a flow of 100% and a bed temp of 80C. Also, I am not having any issues with warping at all. First time ever for me with PETG. I've been 3D printing for over 4 yrs now and warping has always been a problem. Not with this stuff. Get all your Temps right and add plenty of support/brim. Am currently near the end of a 4 day print and all is good.

I got this filament for my Flashforge Adventurer 5M Pro. I use it for a variety of applications, including some load bearing models. I've been very surprised by how well it holds up! It even supports a fair bit of weight while facing the sun every day. My only gripe is that models initially required some tuning for this filament.

Color was true to picture, minimal stringing and printed great. Adhesion was not an issue in my applications.

This is honestly one of my favorite filements. Has the heat settings on the side, works with the AMS Lite with the A1. Holds up well!

Literally filed for a return after three weeks. Ran great. Then out of nowhere started throwing effort codes for "sensor abnormality" over and over. Disassembled the entire unit, cleaned and greased everything back. Changed filaments amd brands of filament. Even reset the software with the newest update available. Everytime, same issue. Creality has zero support for you to resolve the issue yourself. The company is out of China and slow to respond and weak with any response that is given. Ive been so let down with this product and the manufacturer. Sad story.

Great quality and great finish. High quality with no bubbles and consistent thickness across the whole roll

EDIT: I'm updating this review as I've contacted the seller and received a replacement filament from them. The replacement filament so far has none of the issues the previous filament had (no air pockets and much more consistent diameter). I believe I can recommend this now without issues. If you get a bad roll simply contact the seller as they're really trying to be helpful. Also note: photos are from my previous (negative) review, leaving them here for reference on what to look out for Decent price for a product like this, well-packed (vacuum seal, however didn't last long, just a couple of weeks before air got into the bag - not a big deal I guess). No issues with extruder gripping the filament, no "dusting" of filament, no issues with filament breaking, inter-layer adhesion, snapping or anything like that. It hates 180 degrees but is happy with just about everything between 185 and 220 - I settled at 195. Sticks well to the bed (the photo is from before bed calibration, please don't judge me).

(complete n00b to 3d printing) - using a Prusa Mk3s & only Prusa PLA. It was initially tricky to get calibrated & took a few goes to get the first layer calibrated. Printed almost a spool & all was OK - then started to get some lifting. Tried this & i'm not going back to Prusa PLA, its 1/2 the price and STICKS like no tomorrow on the first layer. Feels a little less flexible than prusa but overall i'm super happy with it.

This filament was wrapped well, very well - it's application on the spool made filament management a non-issue. The filament itself bonds well between layers and the finish is nice. I;ll be re-ordering this product!

It's PLA; nothing special but prints well and does what you would expect from the material. I didn't experience any issues with moisture and the fillament is wound very well compared to spools I have received from other brands. Cardboard spool is a bonus.
