High Flow:

There's no denying that Bambu Lab's X1 and P1 series printers are built for speed. However, the motion system, as remarkable as it is, has headroom to be even better. That's where E3D High Flow technology comes in. Using our patent pending internal nozzle geometry first developed for Revo High Flow, we've managed to increase the volumetric flow rate of the hotend by 60%! That means you can expect more reliable and consistent extrusion at the same speeds or bump up the volumetric flow rate limit in the slicer to utilize the motion systems' capabilities fully.

Smooth and Hard:

We've applied our E3DLC™ coating to the nozzle and heater block, adding even more abrasive resistance for all your fiber-filled fun and a non-stick protective layer to prevent plastic build-up on the Nozzle. 

No compromise:

All these new additions come in the same form factor as your stock Bambu; simply reuse your temperature sensor and heater pads, and it drops in place with no adjustment to the mount or part cooling required. You can follow Bambu’s easy hot end replacement guide here.


The E3D High Flow Hot End is compatible with the X1, X1 Carbon, X1E, P1S, and P1P
