Official Creality CFS Multicolor 3D Printer Filament System, Anti-Moisture Filament Storage, Supports 16 Color Printing for K1 MAX/K1 SE/K1C/K1/K2 Plus/K2 Series/K1 Series CFS Kit

So far has worked great overall. A couple of hiccups at first (growing pains), but once the set up is in place and trouble shooting completed, it runs seamlessly. I use a Creality K1, cannot speak to how it works with non-creality printers. It looks nice next to my Creality K1. It has been a blast printing in multi-color for my kids. I use creality and other branded filaments, and they all seem to work fine with this unit. This unit is a bit pricey, but worth it in my opinion if you print daily like I do.

I am using it in K2 plus and the printer detects it as expected. Print speed is awesome. And the print quality is very nice. Will buy again.

Jammed because of user error, it works great when I'm not an idiot that day, I even did the heater mod where you 3d print the heater kit to take the guts out of the dual dryer/heater & jam it in the this CFS works pretty good

So far no complaints. The installation was easier and smoother than I expected. I can recommend it. Everything works well! I have an older K1C from 2024 when it first came out and I am glad I researched a bit and got this CFS instead of the newer version CFS-C. I can understand why some may want the newer version but I think this one is the better option. Only thing I still have to fix is the camera. The firmware upgrade I think made the camera lose its connection so I will have to see about correcting that. Otherwise, all is well!

I have been running the CFS-C on a K1C for over a month now and while I have had a few issues, for the most part it just works. The filament does occasionally fail to retract but a retry usually resolves it. I am printing 3 color pieces at the moment that take over 20 hours. It's probably almost 1000 changes per print. The default settings ensure no color bleed, but I've reduced that by a margin and have been fairly pleased with the results. If your printer is stock you'll have the best experience. I recommend having the shortest straightest filament path, I actually had these filament wear a hole in the ptfe once. The other thing is I don't think the firmware installed properly or during a print I removed the thumb drive and that corrupted the firmware some how. It now drops 50mm after finishing a print which can cause the bed to bottom out and get stuck on taller prints. I'm still working with support to resolve this issue. The K1C install was nice as there were only minimal modifications mostly to accommodate the new filament path over the riser that you print after installation. I will probably buy a second one for my other K1C later this year.

Why did you pick this product vs others?: easy to install. Good quality, more issues than without but worth it! Clogging: More issues with clogging than without and a bit more difficult to clear out

This first CFS from Creality doesn’t work all that well. I’ve done hundreds of prints without it and really haven’t got my money worth with the CFS. I feel ripped off for the price. It has made printing easier and different layers of color easier but only when it works. The bags to keep humidity down isn’t that good (humidity still over 30 in a dry room/environment). They really need a heater in the CFS to bring down the humidity. I’ve owned this CFS for two months now and it prints air between 1/8 to 7/8’s of prints and it can’t finish most if not all slots (a gamble) when I print with Hyper or Rapid filaments. When it does multi color it always misses the first several inches of color in-between color changes so you start seeing missing layers of printing in different sections (prints look goofy with multi color when stacked and looks stringy at transitions). That’s where I feel really ripped off without a solution. It doesn’t live up to its advertising yet. The transition clearly has the color change in the discard but misses the mark when starting the layer. It struggles with its own branded hyper pla/petg spinning also (use plastic spools unfortunately). I even printed supportive covers over spool but CFS can’t handle with or without. Really poorly designed CFS. I bypass the CFS so I could get more reliable fast prints without it. The stock filament sensor is too tight to allow filament through (had to remove the sensor part but kept the pfte tube connector). The stock sensor doesn’t allow filament through without a 45 degree cut and lots of pressure by a human (another reason the CFS fails). I’ll may seek a refund or replacement. If I ever will get a replacement or way recommended how to fix I’ll update my review. Back to old school reliable method of printing without CFS when needed.

Prints well, color is very close to what is pictured. No issues with adhesion as long as proper settings are used. Filament used on Creality K2Plus, did not need to dry, used in CFS with desiccant tray mod printed and full.
