The Creality CFS Upgrade Kit for K1 Series 3D Printers unlocks full multicolor 3D printing capability for your Creality K1-series machine. Designed for K1, K1 SE, K1C, and K1 Max, this upgrade integrates seamlessly with the Creality Filament System (CFS), enabling smooth filament switching, RFID-based filament recognition, and enhanced multi-material performance. Ideal for professional creators, engineers, and hobbyists in Bangladesh aiming to print complex, vivid, multicolor models with precision.

Features:

• Dedicated New Extruder Assembly:

  • Built-in filament cutter for clean transitions.

  • Integrated filament run-out sensor for reliable operation.

  • Ensures precise switching between multiple filaments during multicolor printing.

• Quick Connection to CFS:

  • Compatible with Creality’s RFID filament system for automatic filament detection.

  • Supports smooth, automated filament relaying during multi-material printing.

  • Provides a stable and efficient connection between printer and CFS system.

• Supports Multicolor 3D Printing:

  • Up to 16 color/material combinations when paired with CFS.

  • Enables complex gradients, multi-tone models, and advanced creative designs.

  • Improves color accuracy and material transitions for professional-quality prints.

• Designed for K1 Series:

  • Compatible with K1, K1C, K1 SE, K1 Max.

  • Requires the Creality Unicorn Nozzle for full compatibility.

  • Older K1/K1 Max units may require a hotend upgrade before installation.

• Important Reminder:

  • The CFS unit is NOT included in this kit and must be purchased separately.

Included in the CFS Upgrade Kit:

• New extruder assembly with cutter

• Filament run-out detection system

• CFS quick-connect components

• PTFE feeding accessories

• USB drive for firmware update

• Installation accessories

Specifications:

• Compatibility: Creality K1, K1 SE, K1C, K1 Max

• Required Nozzle Type: Creality Unicorn Nozzle (mandatory for full CFS compatibility)

• Multicolor Capability: Up to 16 colors/materials with CFS

• Firmware Requirement: Update Creality OS via included USB

• Adjusted Print Size When Using CFS:

  • K1 / K1C / K1 SE: 220 × 215 × 250 mm

  • K1 Max: 300 × 295 × 300 mm

• Print Size Without CFS: Unchanged (using stock spool holder)

• PTFE Tube Orientation: Must be inserted vertically; top lid cannot fully close

• Recommended User Level: Intermediate to advanced DIY users

How to Use:

• Ensure your printer has the Creality Unicorn Nozzle installed.

• Update firmware using the included USB drive before operating the upgrade.

• Install the new extruder assembly following the step-by-step guide/video.

• Connect the PTFE tube vertically and align it properly to prevent feeding friction.

• Connect CFS via its quick-link interface for RFID filament recognition.

• Begin printing via Creality OS with multicolor mode activated.

• Regularly check the PTFE path to avoid tension or blockage.

• Maintain proper moisture control for filaments when using the CFS.

• Use OTA updates for future firmware upgrades.

Ideal Applications:

• Multicolor models, decorative prints, gradient artworks

• Character models, toys, complex graphic designs

• Multi-material engineering models using compatible rigid filaments

• Long-duration projects requiring automated filament transitions
