Overview
Bambu Lab High Flow Hotend with Tungsten Carbide Nozzle - 0.4 mm
(For H2D PRO)
HRA 90 Tougher nozzle, lower maintainance
With HRA 90 compared to hardened steel's 74, the Tungsten Carbide nozzle provides exceptional wear resistance. This results in a 50% increase in lifespan when printing abrasive, high-performance fiber-reinforced filaments.
Real High Flow: Save Up to 30% of Your Time
The Tungsten Carbide Super Durable 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 need multi-color printing with the AMS, connect the AMS to the right-side Fixed Hotend.
2. If you want to use the second hotend for support-material printing, we recommend using the Liftable Hotend.
3. 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.
4. PET-CF / PPA-CF / PPS-CF are supported only on the left-side Liftable Hotend.
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.
