[Note]
- Filaments with carbon fiber, glass fiber, metal, or other inorganic particles are prone to clog a 0.2 mm nozzle.
- For filaments containing carbon fiber or glass fiber, it is highly recommended to use a hardened steel 0.6 mm nozzle to minimize the risk of clogging and abrasion.
- Bambu PLA-CF and Bambu PETG-CF have been extensively tested and proven to have a low risk of clogging when printed with a hardened steel 0.4 mm nozzle, while also achieving higher print quality.
Quick Swap Nozzle Design
*Please ensure that the hotend has cooled down before swapping, and avoid touching the heat block (lower section of the hotend) to prevent any risk of burns.
