Description

Creality CFS-C – Multicolor 3D Printing System for K1 Max, K1C and K1 SE

Key Benefits

• Four colors or materials in a single print. The system manages four filament spool slots.

• Printing without internal purging. Material waste generated during color changes is routed externally, preventing waste from accumulating inside the printer.

• Printing continues when a spool runs out. The system automatically switches to filament of the same material type and color.

• Automatic settings with Creality RFID filaments. The material type and printing parameters are detected without manual input.

• Print protection. Runout and tangle sensors pause printing when a problem occurs, while cutter wear is monitored and a warning is issued when necessary.

Innovations and Features

• External cutter and buffer. Multicolor printing is added without major hardware modifications, and installation is straightforward.

• No internal purging. Filament is not wasted on color changes inside the printer, and waste is collected in an accessible location.

• RFID recognition. With Creality RFID filaments, settings are loaded automatically, reducing the risk of using an incorrect profile.

• Automatic continuation when a spool runs out. During long prints, an empty spool does not interrupt the job if another spool containing the same material type and color is available.

• Cutter monitoring. The system issues a warning when the cutter reaches a specified wear threshold, allowing replacement to be planned in advance.

Model-Specific Descriptions

For Creality K1 Max

With a build volume of 300 × 300 × 300 mm, the K1 Max provides ample space for multicolor printing, and the CFS-C makes full use of this capability. Up to four spools can be loaded simultaneously, allowing larger parts to be printed in multiple colors. Large models can take a long time to print, so when a spool runs out, the system continues with filament of the same material type and color. Runout and tangle sensors pause printing if a problem occurs, helping prevent hours of work from being wasted. The external cutter and buffer eliminate internal purging, keeping the printer enclosure clean during color changes. Settings are loaded automatically when Creality RFID filaments are used. The cutter wear warning allows replacement to be scheduled in advance. The system supports four slots and one CFS-C unit per printer. Compatible spools weigh 1 kg and have a diameter of 197–202 mm.

For Creality K1C

The K1C is an enclosed CoreXY printer with speeds of up to 600 mm/s and a build volume of 220 × 220 × 250 mm. The CFS-C adds multicolor printing without requiring you to replace the entire printer. Its four slots are suitable for producing multicolor prototypes, lettering and parts with contrasting elements. The external cutter and buffer enable the upgrade without major hardware modifications, while eliminating internal purging. Automatic recognition works with Creality RFID filaments, saving you the effort of selecting a profile for each spool. If one spool runs out, printing continues with filament of the same material type and color. The LCD displays temperature and humidity, while the desiccant helps keep the filament compartment dry. Compatible materials include Hyper PLA, CR-PLA and CR-Silk, with additional materials available through firmware updates.

For Creality K1 SE

If you already own a K1 SE and want to add color to your prints, the CFS-C provides this capability without requiring you to replace your printer. The unit manages up to four spools, enabling multicolor parts to be produced in a single print job. Waste is routed externally rather than left inside the printing chamber, simplifying maintenance. Runout and tangle sensors pause printing if a fault occurs. Each of the four channels has a white or red indicator, making it easy to check the status of the slots. The system is designed for 1 kg spools with a diameter of 197–202 mm and a width of 42–68 mm, so check spool dimensions when ordering filament. The filament diameter must be 1.75 ± 0.05 mm. Daisy-chaining is not supported, making this a solution for printing with up to four colors per printer.

Who Is It For and What Are Its Limitations?

• Suitable for K1 Max, K1C and K1 SE users who want automated multicolor 3D printing.

• Supports four slots and only one CFS-C unit per printer.

• Requires 1 kg spools with a diameter of 197–202 mm and a width of 42–68 mm, as well as filament measuring 1.75 ± 0.05 mm in diameter.

• Automatic filament recognition and settings loading are available only with Creality RFID filaments.
