Creality CFS-C Filament System
More Colors. More Possibilities. Smarter Filament Management.
The Creality CFS-C (Creality Filament System) brings multicolor printing and intelligent filament management to compatible Creality K1-series 3D printers.
With support for up to 4 filament spools, built-in filament monitoring, automatic Creality RFID filament recognition, and automatic filament relay, the CFS-C provides a more convenient and organized multicolor printing experience.
Compatibility
Compatible with:
- K1 Max 2025
- K1C 2025
- K1 Max
- K1C
- K1
- K1 SE
CFS-C compatibility may require a firmware update and the required upgrade components depending on the printer model.
Easy Multicolor Upgrade
The CFS-C uses an external filament cutter and buffer system, allowing compatible earlier-generation printers to be upgraded for multicolor printing without major modifications to the toolhead.
The external design makes installation and maintenance simpler while providing a practical multicolor printing solution.
External Waste Collection
Filament waste generated during filament changes is routed externally, helping keep debris away from the inside of the printer and making waste collection easier and cleaner.
Built-In Smart Sensors
Filament Run-Out, Breakage & Tangle Detection
The CFS-C continuously monitors the status of each filament spool.
If filament runs out, breaks, or becomes tangled, the system can pause the print and alert the user so appropriate action can be taken.
Cutter Wear Monitoring
The CFS-C monitors cutter usage and provides an alert when the preset replacement threshold is reached.
Automatic Filament Identification
When using Creality RFID-enabled filament, the CFS-C can automatically recognize filament information and compatible printing presets, reducing the need for manual configuration.
Automatic Filament Relay
The CFS-C supports Auto Filament Relay.
If one spool runs out, printing can continue using another compatible spool of the same material type and color, or a different color can be used depending on the selected printing configuration.
Four Filament Slots
The CFS-C provides 4 filament slots, allowing multiple spools to be managed from a single system for convenient multicolor printing and filament handling.
Note: Connecting multiple CFS-C units together is currently not supported.

Minimal Waste. Neat State.
External Waste Collection
Filament waste is collected through an external route — super easy to tidy up filament swaps.
CFS-C
Others
No Filament Purges
No purging needed. No filament debris inside the printer — keeping your 3D printer neat and tidy.
Smart Sensors Built-in
Filament Run-out/Tangle Detection
The status of each spool of filament is closely monitored with sensors.
When a filament runs out, breaks, or gets tangled, it will pause printing
and notify you to take action.
Cutter Wear Monitoring
CFS-C tracks cutter wear in real time and alerts you once it reachesthe preset threshold for replacement.
Smart Filament Management
Auto Filament Identification
When using Creality RFID filaments, CFS-C will automatically read
the filament info and printing presets — no manual editing needed.
Auto Color Mapping
For multicolor printing, if a spool runs out, CFS-C willautomatically
relay printing with another filament of the same material type and color,
or you can opt to complete with a different color.
