CFS compatible filament spool size range: diameter 197-202mm, thickness 42-68mm.
Applicable filament types: CFS is compatible with most materials of medium hardness, such as PLA, PETG, ABS, PLA-CF, PET, ASA, HIPS, dried PVA, BVOH, etc.
In the CFS filament box, avoid using spools that are too wide or too small in diameter, irregular or not smooth (such as with burrs or damage).
It is recommended to use the official Creality Hyper plastic spool series filaments, which we have extensively tested.
All TPU materials and other elastic materials, PVA and BVOH materials that have become soft due to moisture absorption.
Due to different material properties, softer filaments (e.g., TPU) tend to accumulate inside the CFS filament box during printing, while harder filaments (e.g., PPA-CF, PPS-CF, etc.) are prone to breaking inside the tube when printing through the CFS filament box. Therefore, some filaments cannot be printed through the CFS filament box. You also can download the file directly:Filament_Type_Compatibility_with_CFS_Box.rar
The compatibility results of different filaments with the CFS filament box are as follows:
