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.

1. If you print only single-color filament, we recommend using the Fixed Hotend (Induction Hotend) for printing.
2. If you need multi-color printing with the AMS, connect the AMS to the right-side Fixed Hotend.
3. If you want to use the second hotend for support-material printing, we recommend using the Liftable Hotend.
4. TPU85A is only supported on the right-side Fixed Hotend. TPU95AHF/90A is expected to be supported on the left-side Liftable Hotend starting from firmware version U2.
5. PET-CF / PPA-CF / PPS-CF are supported only on the left-side Liftable Hotend.
6. CF/GF-reinforced filaments are not compatible with stainless steel nozzles.
