High Flow Hotend with hardened steel nozzle - 0.4 mm for H2D

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.

High-Speed Precision: Sharp Details Every Time

Say goodbye to under-extrusion, rough surfaces, and loss of detail. Unlike standard high-flow nozzles, Bambu's high yet consistent extrusion ensures crisp edges, flawless texturing, and ultra-smooth surfaces—every single time.

Upgrade now and print faster without compromise!

Filament Compatibility

[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.
