Creality K2 Pro Combo 3D printer with CFS 600mm/s 300x300x300mm

Creality K2 Pro Combo combines an enclosed CoreXY 3D printer with one four-slot CFS filament system. Its 300x300x300mm build volume provides room for larger prototypes, enclosures and models, or a batch of smaller parts.

Four colours in one print
The included CFS automatically changes filament, enabling prints with up to four colours without manually swapping spools. The printer supports a total of four CFS units for up to 16 colours; additional CFS units are sold separately. Creality RFID filament is recognised automatically, while other compatible filaments require their details to be entered manually.

Speed and a heated chamber
Print speeds reach up to 600mm/s, with a typical speed of 300mm/s stated by the manufacturer. The appropriate speed depends on the model, material and print profile. An actively heated chamber reaching 60°C helps reduce corner warping with higher-shrinkage materials such as ABS and ASA. The nozzle reaches 300°C and the heated bed reaches 110°C.

Setup and monitoring
Automatic bed levelling and nozzle-camera flow calibration help prepare the printer for use. A separate chamber camera supports print monitoring, time-lapse recording and detection of certain print failures. Transfer files over Wi-Fi or Ethernet, or use a USB flash drive. The printer has a 4-inch touchscreen and a flexible PEI-coated build plate.

Check CFS compatibility when choosing filament
The printer and CFS do not support the same range of materials. The materials listed by the manufacturer for CFS are PLA, PETG, ABS, ASA, PET and PLA-CF; flexible TPU is not compatible with CFS. CFS controls moisture using desiccant, not a heated drying system. Damp filament needs appropriate drying before printing. The K2 Pro manual permits TPU95 or harder TPU from an external spool holder, with the top cover removed and filament fed directly into the extruder.
