Released in May 2014, the E3D V6 has really become the gold standard premium 3D Printer hotend upgrade.

What’s in the box:

  • Metal parts (heatsink, heater block, heat break, 0.4mm nozzle)
  • Embedded bowden coupling and bowden clip (1.75mm universal and 3mm bowden versions only)
  • Polycarbonate fan shroud
  • Short length of 2mmID X 4mmOD PTFE tube (1.75mm universal only)
  • 12V 30W heater cartridge  (24V available on request)
  • 12V fan (24V available on request)
  • Semitec 100kohm thermistor, embedded in a metal cylinder for trouble free installation.
  • Assorted fasteners for mounting
  • 750mm bowden tubing and threaded bowden adapter (Bowden versions only)
  • A silicone sock to insulate the hot end and nozzle 

Considering this vs other hot ends?  Check out this extremely informative review and installation guide.  Also, check out this list of printer specific installation guides.

Information and description of some features directly from the E3D Blog:

Decreasing size

Our first mission was to decrease bulk – the heatsink and the fan comprise much of the size of the hotend, with bowden fittings in the relevant versions also adding a fair bit of size up top.

The first target for slashing size was the heatsink. We’ve moved to a smaller diameter heatsink that is also shorter in length. By switching to a very thin cutting tool we were able to get more fins in less space and so retain sufficient surface area on the heatsink to still get good cooling out of a smaller heat sink. It’s also 30% lighter than the previous heatsink.

A comparison between the v5 heatsink (top) and the v6 (bottom).

The next vector for reduction in size was the fan duct. After much agonising over the merits of printed parts and the cost of tooling up for injection moulding we went for an injection moulded part.

We’re really pleased with how these turned out!

The new ducts are a great deal thinner and less bulky in all directions than the previous printed versions. We had these done in polycarbonate resin too which makes them ultra tough and resistant to temperature.

The next area to address was the bowden couplers – we consulted with a specialist in tube coupling solutions and took inspiration from how similar things are achieved in the pneumatics industry. We managed to come across a solution so small that it would fit entirely inside of the hotend! The coupling system we’re using is exactly like the screw-in fittings we’re all used to where a collet holds the tube in place and the tubing can be released easily by simultaneously pushing in the collet and pulling out the tube, just a great deal smaller in size.

Can you see the bowden coupling on the v6 on the left? No? That’s because it is entirely contained inside the heatsink. The small black part is just the collet poking out the top because it’s in the “up” position.

For the 3mm versions the integrated couplers were a tiny bit bigger which meant that we had to deviate from our previous groovemount dimensions slightly, but because the previous coupler sat in that space anyway it shouldn’t make much difference in terms of mounting considerations.

Quite the difference!

A Convenient Side Effect

Because the new bowden coupling system sits entirely within the hotend this now means that there is no need for 2 separate 1.75mm products for Bowden users and Direct users. Instead we have a 1.75mm Universal product that has the internal couplers installed. Direct users just use a short length of tubing to line the filament down into the hotend, and bowden users can simply use a longer piece of tubing with a coupler to fix the other end to their extruder.

Making it Easier

Kapton is an amazing space age material that has paved the way for innovations in electronics, aerospace and many other areas in our modern lives. It’s also a total pain in the ass. When done well it works perfectly functionally, it’s just not as clean or easy a process as we would like.

As To deal with the inconvenience of having to remove the fan duct by sliding it either up or down off the heatsink we have designed the new injection moulded duct so that it simply clips into place over the heatsink from the side, with a satisfying snap as it does so.

Improving Performance for Flexible Filaments.

Flexible filaments are amazing and open up a huge range of possibilities for new practical applications in 3D printing, and they’re also just plain fun. However printing them can be really hard work, especially in 1.75mm where the lower diameter of the filament results in a filament that has mechanical properties similar to that of a wet noodle. To make matters worse many of these filaments also have a certain amount of surface tack, that rubber like grippyness – great for printing things like tyres and grips, terrible when you’re trying to make it slide down an extruder neatly.

To solve this issue we have added the (optional) ability to run PTFE tubing all the way from your hobbed bolt/drive gear to deep down into the hotend.


 The PTFE tubing can start right up at the drive system.


The PTFE tubing passes right down through the heatsink


Finally the tubing enters the the heatbreak locating itself in a counterbore at the top of the heatbreak.

Great product and super service

Ordered the hotend knowing it is be the standard of hotendsand it was in perfect shape. It was my first time ordering from printed solid and they are awesome. Was delivered in 3 days and shippings was cheap. Also was well packaged and enjoyed the sticker it came with.

E3D V6 Hot end

All parts were included, went together easily and works perfect. Fast shipping (showed up next day!) Looking forward to increasing number of Voron parts.

Best upgrade

When the kit came it came with everything I needed to get it on my printer. It is the best upgrade I have.

High Quality

I've used clones in the past that give decent quality but the tolerances of the real thing don't compare. The instructions provided by E3D make it simple to install and since my setup is designed for it, the swap took less than an hour. I've been able to hit 285 C and stay stable there, something my clone could barely do at 200 C. I also like the silicone cover for the block, hopefully it keeps globs of filament off of it.

Bad Heater Cartridge. Great Customer Service

After installing the kit on my BIQU SKR Mini E3 2.0 board, making the thermistor changes in Marlin, and heating the hotend, I noticed white smoke come out of the heater cartridge. I contacted E3D by email and was asked to provide a photo of a resistance reading from a multimeter. 19.9 Ohms was too high and a replacement was issued from Printed Solid. The V6 is a classic and has been improved since it's launch over 5 years ago. The online documentation is fragmented accross an old E3D wiki and their new dozuki site. Plus the recommended Tom Sanladerer V6 video is dated and doesn't include product revisions like a thermistor cartridge. Finding the newest instructions could be avoided with a printed instruction sheet provided with the kit. Plus, reading from paper is much easier when completing a technical project.
