The CFS automatically detects RFID-marked filaments and transfers type, colour etc. directly to your 3D printer. For standard filaments, you can also adjust the data manually. For multi-colour prints, the CFS changes filaments with precision and replaces empty coils with similar filaments – quickly and without waste. Not compatible with flexible TPU, wet BVOH/PVA or corrugated cardboard filaments. Removable support activated The CFS gives you get detachable or water-soluble supports that show your 3D model perfectly and without leaving traces. Note: The buffer of the CFS is hidden in a small recess. Please look closely at the packaging material! For your K1C 2025 model: Please note that you need the CFS-C.
