Bambu Lab High Flow stútur með tungsten carbide
Háhraða stútur með tungsten
- Perfect for Abrasive Filament
- HRA 90 Tougher nozzle, lower maintenance
Important Notice
2. Compatible with both left and right hotends on H2D.
3. On H2C, this hotend is supported only on the Left (Lifting) Hotend.
HRA 90 Tougher nozzle, lower maintenance
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.

Quick Swap Nozzle Design
The special design of hotend heating assembly enables easy separation of the thermal and electronic components of the hotend. Simply unlock the latch for quick and easy hotend removal and installation.
*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.
0.6mm and 0.8mm Nozzle - Faster Print Speed
Larger diameter extrudes more filaments per second, resulting in faster print speed

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.
