Product Description: CFS Upgrade Kit for Creality K1 Series 3D Printers
The K1 CFS Upgrade Kit is an innovative solution that adds automatic multicolor printing to Creality K1 series 3D printers — the K1 , K1 Max , K1C , and K1 SE . Thanks to a new extruder with a built-in cutter and filament end sensor, the system enables precise material management. The kit is designed for quick and intuitive connection to the CFS unit , offering automatic filament recognition (RFID), smooth color switching, and convenient software updates.
CFS Upgrade Kit for Creality K1 Series 3D Printers.
The expansion includes the ability to connect RFID-enabled CFS units, which allows for automatic filament type recognition.
Main features of the set
- K1 Series Compatibility : Supports K1, K1 Max, K1C and K1 SE models with Unicorn hotend
- Multi-color printing : automatic switching of up to 16 filaments (with multiple CFS units)
- Precise filament management : built-in cutter and filament end sensor
- RFID support : automatic material recognition
- Simple CFS integration : quick connection and seamless interoperability with CFS units
- System updates : via USB or OTA
- Changed workspace : After installation, the printers workspace changes
How to check hotend compatibility with CFS kit?
To use the CFS upgrade kit for K1 printers , the device must be equipped with an integrated Unicorn hotend. Printers manufactured after 2024 are factory-installed, while older models require both the hotend and heatsink to be updated. The production date can be determined by reading the serial number located on the device's casing. Detailed verification information can be found in the documentation available on the Creality Wiki.
Practical applications
This kit allows you to create models with complex colors without manually switching filaments . It's perfect for creative, decorative, and functional projects. Its advantages will be appreciated by both hobbyists and professionals involved in prototyping, education, and applied design.
Thanks to a dedicated extruder with a built-in cutter and filament end sensor, the system automatically manages the material change process.
