FAQs about E3D Revo™ updated 12 May 2023

What is Revo™ High Flow nozzle?

It is a brass nozzle with revised internal geometry to allow printing at high flow rates. Based on E3D's testing methodology, the following are their test results when printing PLA at 220˚C.

0.40 mm nozzles see a 38% increase in the volumetric flow rate (18mm³/s) 

0.60 mm nozzles see a 57% increase in volumetric flow rate (22mm³/s) 

0.80 mm nozzles see a 64% increase in volumetric flow rate (28mm³/s)

1.00 mm nozzles have a volumetric flow rate of 35mm³/s 

1.20 mm nozzles have a volumetric flow rate of 37mm³/s 

1.40 mm nozzles have a volumetric flow rate of 37mm³/s 

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.

Do I need to use a Revo™ 60W HeaterCore in conjunction with High Flow nozzles?

The 60W core adds extra power for printing high flow at higher temperatures for example with materials such as Polycarbonate. For those users printing with PLA and PETG the 40W HeaterCore will be more than sufficient, but if you’re seeking the maximum flow performance then we recommend pairing your nozzles with a 60W HeaterCore. 

What does the Revo™ High Flow Single Nozzle Kit ship with?

The Revo™ High Flow Single Nozzle Kit ships with a single 0.6mm Revo™ High Flow brass nozzle. Revo™ High Flow is only available in 24V.

Reports of clogs using E3D Revo™

The short answer is that the nozzle temperature needs to be increased by at least 5% from what you’re used to, so clogs are probably due to the the nozzle temperature being set too low. So if you were printing PLA at 180°C, try increasing it to 210°C or more when on Revo™.

Stefan from CNC Kitchen made a very thorough review of the Revo™ land explains the temperature gradient perfectly, with cutaway diagrams of Revo™ compared to V6.

What is the flow rate of the Revo™?

The flow rate is dependent on many factors such as nozzle size, nozzle temperature, nozzle type, extruder force, filament type, filament width, filament quality, extrusion type etc. E3D lists Revo™’s volumetric flow rate at 10.5mm³/sec using their testing methodology. In plain English that means they think you should limit your printing speed to about 130mm/sec when using the standard 0.4mm nozzle with a 0.45mm extrusion width at 0.2mm layer height when printing PLA at typical temperatures.

Check the math here.

Our own simplified testing which everyone uses (extruding into free air until the extruder skips), with an E3D Titan extruding PLA at 200°C with a 0.4mm Revo nozzle was able to push about 15mm³/sec without issues, with 18mm³/sec possibly the absolute limit for this specific configuration. Note that this simplified testing result is hypothetical since it ignores many real-world conditions, but we included it because it’s just a simple data point that everyone can understand.

What’s the difference between the various Revo™ models?

Revo™ Six has the same form factor as the V6, while Revo™ Micro is slightly shorter in Z height. Revo™ CR is meant for Creality printers and Revo™ Voron for Voron printers. Revo™ Prusa Mini and Mk3 Edition are meant for the respective Prusa printers. They are otherwise functionally equivalent, including the nozzles.

I’m getting MINTEMP or MAXTEMP errors

First, always check the wiring and connectors. Many times, a loose connector or wire is the source of the problem. If you are very sure that it is a hardware issue, please get in touch with us via chat or email and we will be able to assist you further.
