Creality Official 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 PETG filament has been a solid and dependable choice for my 3D printing projects. The dimensional consistency seems excellent, and it feeds smoothly through my printer without jams. The vacuum-sealed packaging kept the filament dry and ready to use, which helped avoid bubbles and clogging during prints. I appreciate the balance of strength and flexibility, making it suitable for functional parts that need durability. Layer adhesion is strong, resulting in sturdy prints with a clean finish. The Rating of the review is 5, as it has delivered reliable performance across multiple prints. I did notice a bit of stringing on more complex models when print settings were pushed too fast, but dialing in normal PETG temperatures resolved most issues. It also appears a little sensitive to higher heat, so staying within recommended ranges gives the best results. Based on my experience and feedback echoed by other users, the filament performs consistently well on most 1.75mm FDM printers and is easy to work with once tuned properly. It offers dependable results for both hobby projects and functional prints. I would confidently recommend it to anyone looking for a reliable PETG option for everyday 3D printing needs.

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.

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!

This stuff prints very clean, and makes strong parts as long as you don't run high temperatures. Used some settings (260 C) that ran great with other PETG, but with this it printed horribly and the parts were very brittle. Keeping it 240 or lower works great.

The 4 pack is convenient, inexpensive quality PETG. I keep going through this because it works well on my printers.

I have ordered quite a bit of filament through Amazon and this has been consistent with what I have come to expect from decent quality PETG. No clogs, no snapping mid print, and it feeds reliably through the whole spool. Dimensional consistency has been solid which matters more than people realize when you are printing functional parts that need to fit together. Good value for the quantity and I would order again without hesitation.

I honestly hesitated purchasing Creality's CFS, because there were a fair amount of complaints about certain aspects of the machine. I'm disabled and have challenges with mobility and dexterity. I love my 3D printer and use it very frequently for all sorts of really great projects, and the 3D printer provides significant quality of life I could not find elsewhere. The CFS system I've recently purchased and installed has doubled the ease of use and joy of using the 3D printer I own. I'm honestly a little speechless. You just put a spool in the slot and feed the filament into the receptacle, and that's it. No more manual removal or spool nonsense. It's all accessible and visible, and provides accurate relative humidity and temperature readings within the chamber. I'm really really pleased with my purchase and honestly immediately decided to add more once I am able to! If you have been hesitant about the multicolor systems, just make the jump! I regret not getting into it along time ago!

(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.

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).

Had good luck with a white spool of the same brand, but the black filament I just received is no good. Poor bed adhesion, stringy, and overall poor quality results with printing. Update: Vendor reached out to me regarding my experience and offered to replace or refund. This positive customer service experience was a pleasant surprise and I must commend them on their efforts to resolve the issue.

purchased three reams of filament in 2020 from esun . i wasn't having any success , prints were blotchy and just plain ugly. initially i thought it was something i had done. tried many things to improve my prints from rep[lacing parts to drying . with only marginal results. I lost interest. this week i thought i would give it i another go. I even purchased another cheap used printer. same results. Finally decided to get this filament . as a last ditch attempt. it worked perfectly. results were clean with minimal effort. So yeah . this stuff is great. it worked. certainly recommend it.

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