Great to have

Honestly I have not used these yet. My speed appears to be limited with the regular hotend. I will be trying up the speed some more to get faster prints. Hope these can help with crossing over 200mm/sec and still be correct.

Dramatic improvement over stock

I purchased these the week they came out, they were a dramatic improvement over the standard nozzles.

That being said, the price difference between this and an Obxidian HF makes it a tough choice to go with a brass nozzle.


Great service and fast shipping.


Optionally pair this with a 60w Revo HeaterCore

From E3D:

Higher Flow

Revo High Flow increases your setup's volumetric flow rate, enabling you to print faster!

How does this work? Unlike our previous E3D High Flow Hotends (Volcano and SuperVolcano), Revo High Flow maintains the exact same form factor as standard Revo HotEnds; this means there is no need to adjust your pre-existing mount and fan duct setups! Revo High Flow uses a unique custom internal geometry to increase the surface area for improved thermal transfer to the filament. 

See how it works in our video! Or read a full deep drive on our blog.

More nozzle sizes

Revo High Flow unlocks higher flow for existing 0.4mm, 0.60mm, and 0.80mm nozzle sizes and adds 1.00mm, 1.20mm, and 1.40mm nozzle sizes to your arsenal.

Including the standard Revo nozzle range, which is interchangeable, this allows for a wide range of printing applications with 0.15mm nozzles all the way up to 1.40mm!

Lets talk numbers

Empirically providing useful volumetric flow rate figures is a challenging task. To make our figures as close to real use case as possible, we have stuck to a semi-standardised testing procedure. 

It is important to note that when we subject other high-flow hotends on the market to the same testing procedure, the maximum flow rate claims fall short when appropriate print temperature, track widths and layer heights are used.

Similarly, we have benchmarked standard filaments that are not necessarily designed to be used in high-flow situations. If you use HTPLA, PLA³ filament or other specifically high-flow designed materials, the maximum volumetric flow rate you can achieve with Revo High flow is awesome!



Do you need the new 60W Revo™ HeaterCore to use High Flow? 

For the majority of uses cases the standard 40W HeaterCore will suffice, however, if you want to maximise your performance with high temperature materials such as Polycarbonate we would recommend upgrading to the 60W core to reach the full potential of Revo™ High Flow. All ‘High Flow Hotside’ kits come with a 60W core, but individual or triple packs of high flow nozzles are also available to cater for those who don’t want to upgrade to 60W.

Why is 60W core only available in 24V, and not 12V?

The universal standard 40W version is available in 12V and 24V to cater for everybody. However a 12V-60W core results in a higher current than the rated current on a number of printer mainboards in use in the market. This doesn’t stop people with 12V systems using High Flow nozzles – they just won’t get the absolute peak flow performance in some niche printing cases.

Will my Z-offset change when I install a Revo High Flow nozzle? 

Revo Nozzles are all manufactured to the same length (within ±0.2mm) you will not need to reposition your Z-probe or re-level your bed. You may need to adjust your Z-offset to get a perfect first layer though. 

How do I tell the difference between a standard nozzle and a high-flow nozzle? 

A high-flow nozzle can be distinguished from a standard nozzle in two ways: 
- The circle where the high flow geometry in inserted, located on the bottom of the nozzle (only visible when clean). 
- When the sock is removed the nozzle diameter followed by ‘HF’ is engraved for easy identification.
