Since Sanjay and I met one another in 2011
we've been completely obsessed with HotEnds and 3D printers
and how to drive forwards the performance of both of them
So about ten years ago, Josh, Sanjay, and myself got together and we decided to redesign our all-metal HotEnd
In that time we've made an awful lot of components
and we have really been driving forwards the performance of 3D printers since then
(Josh) We've been focusing on very heavily on making the product easier to use and making it more accessible
while maintaining the same level of performance that E3D has always been known for
(Dave) So today I'm really pleased to be able to bring you the culmination of all of that
which is the RapidChange Revo™ ecosystem
(Josh) Revo™ is the first ecosystem in the RapidChange™ family
that we're bringing to market
and there's going to be lots of innovations coming
within the RapidChange ecosystem in the next couple of weeks and months
(Dave) We've made our new HotEnd far more affordable, far more accessible
for everybody in our community
from the way that you mount it
to the way that it connects to your 3D printer
this is now truly the one HotEnd that you would ever need
(Josh) and I'm really excited to share with you a whole bunch of the technical details
that's made RapidChange possible today
so I'd love to hand over to the team that have made it all possible
and whose heart and soul has gone into the production of this product
Come with us, and join the Revo-lution
(Laughs)
(Rory) To use Revo, once you have your heatsink and HeaterCore
fitted onto your printer you literally just unscrew the nozzle
and when you want to put a new one in
you screw it in, and off you go
straight back to printing
So what makes Revo Nozzles different from other nozzles
is the complete lack of requirement for tools
Unscrew a nozzle when it's cold
and then put the new one in
No tools, no hot tightening, none of that
At launch there's going to be a range of brass nozzles
0.25, 0.40, 0.60, and 0.80mm
In the future we're going to be working on abrasive nozzles
So the ObXidian nozzle, which is ultra wear-resistant
that's coming out shortly
Beta testing is really important at E3D
as it allows testers to give us feedback
and really optimise our designs
For Revo we had about a thousand beta testers
testing over the course of several months
which gives us tens of thousands of hours of useful beta testing
We're already working with lots of different printer manufacturers
to try and integrate Revo into their systems
Because of the low cooling requirements it's really easy to integrate it into whatever you need
(Travis) The Revo HeaterCore is the latest architecture
for what was the heater block in older extrusion systems such as V6
where they had a heater, a sensor, and a heaterblock
to hold the nozzle and heatbreak all together
The HeaterCore has all of that included
and it simply clips into your cold side
First you need to simply wire it up to your printer
with the heater and sensor cable here
Then using the spring you clip it into your cold side
And you can simply swap your nozzles in and out through the centre
What's inside is a ceramic heater
made from a ceramic screen printing process
And incorporated in there is the thermistor or temperature sensor
The design was actually revised quite a few times
Thanks to all the valuable feedback from our beta testers
What makes the HeaterCore safer is that it's designed with a PTC
or 'Positive Temperature Co-efficient'
which means as the heat increases
the power decreases
so that you never run into overheating problems
Compared to other heaters on the market
this is designed with a copper alloy
which has a much higher melting temperature
and a much higher working temperature
unlike the aluminium alloy heater blocks
(Rory) We use the term 'hot side' to refer to the bit that is heated
and the 'cold side' to refer to the bit that is attached to the printer
At launch we're going to introduce the Revo Six and Revo Hemera
As well as Revo Micro, which is a really small, optimised heatsink
Shortly after launch we also have a Voron and Creality version
(Josh) So, the Revo Hemera XS
is an improvement on our standard Hemera
so it's got a smaller motor on it
and the heatsink has been modified to take the little spring clip
which supports the Revo HeaterCore
Effectively it's an upgrade for your Hemera
The Revo Six is essentially a backwards compatible version of Revo
The heatsink is designed to be the same geometry as a standard V6
which means that it should fit in essentially printer that currently uses V6
and it's also got a slight modification in it to ensure that the overall height is the same as a standard V6
I particularly like this version as V6 was one of the first products that I designed at E3D
We're using groove mount in the Revo Six because V6 uses it
and I know that's a terrible reason because everyone hates groove mount
but it's a dying breed in the industry
but it's something we want to ensure we maintain for backwards compatibility
In fact, one of the terrible secrets that I have is that I broke groove mount
because when I was redesigning this heat sink
I measured – I think it was a J-head –
I measured it wrong
and so we changed groove mount by 100 microns
Yes, I'm sorry for everyone that was there back then
(Rory) Revo Nozzles are a three part assembly made out of drawn stainless steel tubing
which gives us titanium-like performance
Revo Micro uses the titanium-like performance of the Revo Nozzle to allow us to make a really small heat sink
which is around about 30g for the entire HotEnd
meaning you can move it around really quickly and achieve those really high print speeds
The Revo ecosystem is really easy to integrate into 3D printers
If you're a printer manufacturer and want to integrate Revo into your system
just get in touch with us and we'll be happy to
come up with custom mounting solutions to fit your needs
The best way to get in touch with us is directly through the website (https://e3d-online.com)
(Zaneta) Currently the Revo team consists of eight people
plus a team leader, but of course we have more people trained in the whole company
so if needed we can expand the Revo line
It was not an easy exercise because the whole Revo product is a very innovative product on the market
All of the processes, all of the machines and equipment is very new to the team, but with the whole company's support
and engineering effort, we did manage to set up the whole Revo line properly
within a few months, so it went very well at the end
and we've been able to train all of the operators properly
the HeaterCore process consists at the moment of several different stations
we are building everything in-house
we have control of every single process
we are checking if the product is built to specification and if it's working correctly
I can just add that it was quite a challenging time for all of the production team
and it was a great learning time for us
we know much more than we knew a few months ago, a few weeks ago
and we are improving every day
(Clare) We want to make sure that the ecosystem is as thorough as possible
to cater for all use cases
just as we have done for the last seven years with the V6 ecosystem
We've got a really big ecosystem to roll out over the next 12 - 18 months
Firstly we'll be doing ObXidian, the abrasive-resistant solution
and that's going to be quite closely followed by high temperature variants
and high flow
High flow is the one I'm most excited about myself
I can't wait to get that on the market and see what people do with it
One little announcement I can make today:
As well as the hot side ecosystem roll out
We've got the Creality upgrade kit which is next on the list of upgrades
for all users out there of Enders and CR-10s
We want to encourage open source as much as we can
that's how the community has driven the industry to grow as fast as it has over the last ten years
and we don't want to stifle that growth
equally we have had to change our IP policy to be able to protect ourselves
and our bottom line, but also to protect the wider industry
and the quality of 3D printing
One of the things that the industry has struggled with over the last seven years, eight years
since the launch of our V6 all-metal HotEnd
is cheap clones, cheap knock-offs
they might look like visually at a bit of a distance and a bit of a squint exactly the same product
but they're not, they don't produce the same reliability of extrusion
and the same user experience
and we want to make sure that that doesn't happen in the future to people
purchasing cheap knock-offs
Although we've patented Revo and there's a lot of IP protection around it
We are ensuring that the cold side is completely open source
So, the dimensions, the specifications of the cold side
