E3D High Flow Nozzle for Revo Hot Ends

Unlock blazing-fast print speeds without rewriting your entire printer configuration with the E3D Revo High Flow Nozzle. Specifically engineered for the RapidChange Revo ecosystem, this high-performance component drastically elevates your hotend's maximum volumetric flow rate. Now you can slash production times on large structural objects, take full advantage of high-speed motion systems, and maintain flawless extrusion consistency.

By maximizing internal thermal transfer within a completely standardized physical profile, the Revo High Flow gives you all the speed of a long-melt-zone system without any of the architectural headaches.

Optionally pair this with a 60w Revo HeaterCore

Drop-In High Flow Geometry (No Re-Mounting Required)

Traditional high-flow hardware alterations (like Volcano or SuperVolcano systems) force you to change your physical hotend length, requiring redesigned toolhead mounts, modified cooling fan shrouds, and a recalibrated Z-height. The Revo High Flow bypasses these issues entirely by packing advanced heat-splitting architecture directly into the standard Revo form factor.

• Identical Form Factor: Maintains the exact same outer dimensions as standard Revo nozzles, allowing you to swap it straight into your current toolhead setup with zero hardware modifications.
• Core-Splitting Heat Transfer: Utilizes a custom internal geometry that physically splits the incoming filament strand, maximizing the internal surface area contact to quickly melt plastic from the inside out.

Push Your Volumetric Limits

Whether you're sticking with standard components or building an absolute speed demon, Revo High Flow scales directly with your system's capabilities.

• HeaterCore Flexibility: While your standard 40W HeaterCore delivers fantastic flow gains for everyday plastics, pairing this nozzle with a high-power 60W Revo HeaterCore (24V) ensures stable thermal performance with demanding, high-temperature engineering filaments like Polycarbonate.
• Expanded Size Range: Take control of high-speed manufacturing with traditional 0.40mm, 0.60mm, and 0.80mm sizes, or unlock ultra-wide structural paths with 1.00mm, 1.20mm, and 1.40mm configurations.

Frequently Asked Questions

Do you need the new 60W Revo HeaterCore to use High Flow?
For the majority of use cases the standard 40W HeaterCore will suffice. However, if you want to maximize 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.

Why is the 60W core only available in 24V, and not 12V?
The universal standard 40W version is available in 12V and 24V to cater to 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), meaning 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.

Specifications & Quick Identification

• System Compatibility: Seamlessly integrates with all E3D Revo Hotends (Revo Six, Revo Micro, Revo Voron, Revo Hemera, and Revo Roto).
• Aperture Selection: Available from 0.40mm up to 1.40mm for industrial-scale manufacturing.
• Filament Diameter: Precision engineered exclusively for 1.75mm extrusion setups.
• Easy Tracking: Identify your high-flow variants at a glance by looking for the circle where the high-flow geometry is inserted on the bottom of the nozzle, or by checking the engraved size followed by "HF" on the nozzle body under the silicone sock.
