Real High Flow: Save Up to 30% of Your Time
The Bambu High Flow Nozzle's optimized melt zone enables significantly increased volumetric speed, achieving up to 62.5%1 higher max volumetric speed and reducing print time by up to 30%2 with ease. The larger your model, the more time you save—especially for prints with extensive infills.
1. Tested with ABS, Ø240mm single-wall cylinder, 0.2mm layer height, 1.0mm outer wall, 280℃ nozzle temperature, spiral vase mode on.
2. Tested with PLA Basic, 15% infill, 300x300x300mm cube.

[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.
