I have had SO MANY PROBLEMS with leaks from the nozzle or heat break not being properly seated on my Micro Swiss direct drive setup. My printer's been down for two weeks because I basically wrecked a heatsink and was too broke to afford a new one. The thing that really, really excites me about this (and the Prusa XL) is the way it eliminates so many of those connexions. I don't care about the quick-swap, though that's very cool. I'm just happy to see it reduce a point of failure. Since the XL has the same feature that I care about, I'm feeling confident that either E3D is willing to license this at reasonable rates, or else that the "single piece nozzle and heat break" isn't part of the patent. Either way, I'm very happy to see this innovation come along and I'm sure that in the near-ish future we'll see plenty of options. Now I have to go do some research and figure out how I'd mount one of these on an Ender 5 with direct drive...
@@hazonku I fitted a Titan Aero to my Anet A6 3 years ago and it greatly improved the quality (as well as upgrading the electronics and drivers), the Hemera should be even better and easier to mount.
9:00 actually, the heated bed on the E3D toolchanger I use at work reaches 80°C faster than the 40 or 50 W hotend reaches 270 °C. And for toolchanging, faster heating times is a very welcome improvement.
Adoption is always the biggest issue with any new system. Given E3D's track record, I think it will only be a matter of time before everything is sorted out and we get 3rd party components.
It looks like they did open up part of it for 3rd party use. They patented half the assembly, allowing 3rd party nozzles to use their attachment. The only part they cant use from the sounds of it is anything below the thread. Joel over at 3dprintingnerd posted an interview with e3d and they briefly covered it.
Dynamic temperature changing would be great for supports. PETG in particular has crap adhesion if it's printed cold, so it would be ideal for zero-gap supports using a single nozzle.
Thanks for the video. I switched from .4 to .6 mm nozzle a year ago, and I have never looked back. I mostly print functional parts, and so far a .6 nozzle serves me well. It's not that much rougher than a .4 mm, and I find the print settings to be more important.
Of the 4 times I've ever attempted to swap nozzles on my v6, I ended up bending my heatbreak twice, got the nozzle permanently stuck inside my T wrench once, broke my thermistor wires once, and burned myself just about every single time. If this nozzle is even SLIGHTLY better, while still being the same form factor, I'd fork down $200 for it right now.
Unless this had significantly improved performance over my V6, I don't see a reason to to upgrade. Honestly never had an issue swapping out my nozzles, and the broad compatibility of 3rd party nozzles has been a huge benefit to me. I'd like to see you throw this on your Voron and see if the quick-change functionality has improvements to your general workflow.

I've had to deal with two leaks in the past year, and they have put me off changing nozzles as frequently as I'd like. That quick change system is the biggest plus to me. But I'm also interested in seeing the throughput of the Micro can keep up in faster prints, now that you'd have decreased mass up top. Same with the Hemera, seeing as I'd be between one of those two.
It just makes swapping nozzles so much easier and quicker, though. To the point where I can pretty much decide on a per-print basis whether I need the fancy 0.25mm nozzle for a detailed print, or a 0.8mm nozzle for a quick and dirty functional print. Unscrew one, shove the other one in, done. I don't have trouble swapping nozzles either, but it's still a 10-15 minute job between finding nozzles/wrench and switching them out and hot-tightening and re-zeroing the Z axis on the printer and all that. About the only disadvantage is price, but I'm sure the Aliexpress clone machine is working overtime copying this system right now if you're cheap.

@@AndrewAHayes I find the price quite affordable save the nozzles. But I'm not getting it day-one. I'm going to wait for a Nozzle X or similar first. I haven't had to replace mine in over a year, so it's a one and done for me.
Honestly, nozzle-swapping was one of the appeals to Mosquito for me; having multiple V6-styles (all original, saying style because some is hemera/other sinks like prusa), the block rotating along right as you can't find a vice or so is a nightmare. The whole concept of the circular "pcb-style like our beds" heater is also interesting, it might lead to some very interesting nozzle/hotend designs especially in high flow/multi-colour/mixing stuff (imagine 3 extruders, 1 nozzle/heater, and mixing filament like you'd mix ink on an inktjet, using the whole adaptive pressure stuff we got to make some cool stuff)... Also, this nice way of swapping might make multi-extrusion width in one print without toolchanging MUCH easier. 0.4 for detail, and then 0.8 or larger for the big stuff layers (some of my models defo could use that)
So a nozzle changer for your tool changer, that would be interesting. Perhaps as one colour hotend is cooling down for a nozzle change, it could print other colours in the meantime or whatever.
I'm curious how and if this will succeed, especially in terms of the patents and how E3D will be dealing with 3rd party manufacturers willing to make Revo nozzles.
Looking at the pattents i believe they are more on the core heater technology. I also imagine them them willing to liscense their tech at a reasonable rate considering their past behavior with other organizations they have partnered with in the past.
The approach I'd recommend is for E3D to assign their Revo patents to a suitable open patent alliance AFTER their next generation system has been in the market for a while. E3D has proven their support and approval of clones and to improve low-end printers, but there is no need for them to cannibalize their own business to do so. A delay of one generation should strike a good balance.
I believe the 'Nozzle-break' with a heatbreak integrated into the nozzle was already patented and then the patent was abandoned, I don't know the exact patent number it was I looked at. So I think E3D couldn't patent the nozzlebreak even if they tried.
I pre-ordered the micro. Will put in my coming Stealthburner upgrade on the Voron 2.4. I was always too lazy to swap nozzles on my printers, but with this system I see myself switching from 0.4 to 0.8 pretty often. I hope they bring the nozzle-X in the future, that's their current king for the V6, so maybe the same thing for the Revo. Likewise, I really don't mind them wanting to earn money on this product, they gave so much already in giving out the V6 design for everyone. Hopefully they will license some things out to other manufacturers, so we get more choices. Don't be like Slice engineering, cause F them.
I just put mine on an Ender 6. It is the best upgrade I have ever done. It bolts right on and works. Changing the nozzle is fantastic. Go from draft to quality print in under a minute. I can print fast with better quality. I wish I did it soon, great job guys.
What I'd like to see is an adapter nozzle for the quick swap system, which let's you install a standard nozzle onto a quick swap part. The heat transfer wouldn't be as perfect, but the ability to not only take advantage of the hand-tightening quick swap ability, as well as being able to retain use of your specialty nozzles, such as the CHT, would make it worth the downsides.
Heater block are round; Pie are square. Jokes, aside... Good news, no more breaks in the assembly (nozzle, meltzone, heatbreak, PTFE shaft) where a lot filament jams. Bad news: Nozzle wears out, you have to replace the whole filament assembly (more cost)
You perfectly summed up what is holding me back from getting Revo now. High temps and harder than brass nozzles are a must. Thanks for the look through!
I’m excited for this system! I maybe have a need to print in a larger nozzle size once in a blue moon - but I always put it off because I really dislike the process of a current nozzle swap. I’m sure I’ll print more aggressively in different nozzle sizes after this. It’s also a big win in terms of accessibility - yet to see how it has handles, but I can imagine this will only make swapping nozzles easier for people with limited mobility.
@Thomas: if you haven't already, would love to see how you get on upgrading the Mk3(whatever revision) to support the Revo Six - I envision connector "additions" on the hot-end/extruder cabling, and maybe some "light fighting" to get the Noctua fan working, but otherwise it then becomes plug 'n' play...
Great review, as ever Thomas, thanks! Been looking forward to these coming to market since I first had a look and feel at TCT Oct 2021. The ease of nozzle swap is such a nice feature even/especially if only used occasionally - it works every bit as easy you show and totally removes the faff involved with height offset recalibration vs a threaded nozzle; great to see E3D continue to set the pace in evolving extruders - they really are beautifully engineered products.
I am one of the Beta testers for this hotend system. Before this, I bought 5x copies of the v6 hotends just to avoid doing nozzle changes (I do not like the risks of burning my self, damaging the nozzles, not getting it tight enough etc) when I want to either use a smaller or larger nozzle (in 1.75 filament I had 0.2, 0.4 and 0.8mm nozzles, and for 3mm filament I had 0.4 and 0.6mm - I made a quick swap system to swap between 1.75mm and 3mm filament - though it requires a printer restart). For this, having the Revo quick swap nozzles are great (no need to restart printer, just cool it down, swap and heat it up). That said, this system is not for everyone: rewiring of printers that does not have the right connectors; high temp printing or printing with abrasive filaments. If you also need high flow rates, this will struggle (simple physics on how fast the heat can be transferred to the filament). However for users that want a simple way to change nozzles, this is a great system (note that a couple of companies are working on different ways to solve this, so go check them out also). No special tools, no extra procedures (like hot tightening) etc. just simply unscrew it by hand, and screw the new one in by hand. Also the heatup times are fantastic. I typically print on diluted wood glue (spread over glass), which means that I preheat the bed for quite a while (to dry the wood glue), while still slicing and figuring out all the print settings. As soon as I am ready, I heat the nozzle and is printing within a minute. Also the small size of the heater means it cools very quickly (once power is removed). An extra note, the Revo Micro uses a 5v fan on its heatsink - this makes it a bit harder to install on some printers. While it comes with a step down converter, it have to be installed correctly. The fan is also a 25mm one (replacements are hard to find). For cooling fan shrouds, adjustments may be required coming from the v6.
LOVE the new REVO ecosystem. This is what 3d printing really needs! This makes one of the most frustrating parts of maintenance significantly easier. The PTC aspect of this heater is one of the most interesting to me! It will make the systems MUCH more stable. I figure we may have a specific high temp REVO like you said. I will be curious to see what that top end temp looks like!
I would like to say Thank you to E3D for sending this to you , also thank you for the look ahead on this increadable product . I am really looking forward to being able to buy the full package when it becomes available . If this works as it looks like it will it will solve alot of problems before they happen .
The fact I don't have to fenangle my way around a 280 degree lump of metal to change a nozzle is worth the price. I love using different nozzles on my MK3 but the leak chance always puts me off. I hope they release a hardened revo nozzle. or a Nozzle X
my biggest headache with my MK3s was incorrectly changing out my V6 nozzle. didn't get it tight and had leaks which lead to a whole bunch of other issues - including thermal melting of the extruder parts and complete rebuild. Short response - Revo appears to be a simpler system so that I could change nozzles reliably - or maybe I should just gain more experience changing my V6 nozzles!

Hear, hear. I loathe having to risk working on a "hot" hotend. And I've had to deal with two leaks so far, it's not a fun time.
This. As someone who relies on my printers for my income, the Hemera is awesome, but can be prone to leaks between the nozzle and heatbreak which is a constant worry when printing 24 hours a day, 7 days a week. Super excited for the Revo.
How would the "fenangle around a 280 degree lump of metal" change? It's ceramic now, granted, but that nozzle is still jammed right up against the heater block, and the OD of the "ring" of the nozzle is smaller than that of the heater. Meaning it's pretty much impossible to grab and turn that nozzle without touching the heater or its sock. Edit: Typo

@@pr0xZen You don't have to do it hot anymore. You can do it cold, at room temperature. The heat break and the nozzle are a single assembly, unlike the V6.
I am a bit cricitcal regarding the PID tuning. Why should the PID parameters stay the same? It has a way different thermal mass, even though the thermistor is the same
a conservatively tuned pid loop should work reasonably across quite a range of heaters, so it is likely that the new hotend will work with no tuning... but yes, i'd recommend tuning it anyway.
You really want to make a Pid tune. If you don’t, you won’t get the full potential of the heating element.. or it will unnecessarily over and undershoot.
You think that's bad? The heater block is supposed to be self regulating. Have fun tuning that PID, where the reaction of the heatblock is totally non-linear to the power applied.
@@randomname3894 Not approaching the max temp, where the cartridge starts to "self regulate" by increasing it's resistance. And as I'm pretty sure was covered in the video, using the same PIDs is probably "good enough." So yeah, I guess magic.
Im excited for this and not even because of the rapid nozzle change, because it eliminates torquing nozzles and leaking plastic between nozzles and heatbreaks.
I ordered mine earlier today before this video came out mainly because it makes it much easier to change nozzles hopefully without blockages. I have not experimented with various nozzles size just because of the issues I had with blockages.
for mating, they heat up the brass most likely so it expands just enough for the steel core to slide in, and when it shrinks it forms a very strong interference fit with it most likely
I hope there's going to be a hf version soon. Flow wise, the revo really just can't compete with hotends like the dragon and rapido for the same or lower price.
Agree 100% with your comments Tom. I think it could possibly be a nice upgrade from a V6 if you're starting a new printer build but for me it's not worth upgrading my perfectly reliable current setup with tons of options from various manufactures.
Interesting, I was going to upgrade to a Hemera with: a titanium heatbreak, plated copper heater block, 40W high precision heater cartridge, PT1000 Temp sensor and a Nozzle X nozzle. But you're right Tom, I don't really *NEED* all that, a Revo Hemera will probably be more than capable for my use case, but they (Revo Hemera vs Fully Upgraded Hemera) cost basically the same
Ultimaker swappable cores are £100. (S5 anyway). The Uktimaker is amazing because it can easily print any material (bar peek etc) but at a cost and you can’t even swap nozzles - u need to replace the whole print core every time. This really enables home printers to experiment cost effectively with all kinds of materials and nozzle sizes. Hobbyists should love this as they can learn much more about printing, and much more about materials and their applications
Hi Thomas. E3D says it is a drop in replacement for V6 assembly but what about the PTFE tube there is on Prusa extruders ? Doesn't the length of the Revo nozzle alter the length of the ptfe tubbing ?
Tom: The Revo heater is rated at 40W. The V6 was only 30W. The new heater also wraps around (what is now) a very small heater block. I've ordered a Hemera with a full set of nozzles. I can't wait to try it with some of the larger sizes on my Prusa Mk3s.
@@Kalvinjj Yeah, for some reason Prusa decided to run all the cables in the hot end all the way back to the electronics box. As a result, the shorter connectorized cables won't fit on a Prusa i3 printer. Though, instead of a separate SKU of the whole assembly with longer cables, I think a cable extension accessory would be a better product.
@@Sembazuru Eh that's kinda annoying then... I agree about a cable with connectors at the end (for everything: heater, thermistor, fans and probe) being a nice idea. Given that I have the crimping tools my bet if I was in that situation would be to cut the cables and add the connectors, but I understand that not everyone has the tool and a bunch of connectors waiting for use (heck I might not have the perfect one either...).
Just as a note with Hemera, The new nozzles might fit in the original Hemera but you actually need a new Revo specific heatsink for it to work correctly.
So negative from my side of view: First, you can not use 3rd party nozzles anymore, only original. Since you can get nozzles dirt cheap, this is one thing that will increase the printing price. Second, integrating everything like with the combined nozzle means a) you need specific, most likely patended replacement parts, and b) you throw away parts that still work.
@@sterkriger2572yeah I figured there would be.. honestly maybe rather than lamenting the use of normal nozzles more people should adapt. The thing is... I couldn't see many people actually using it.
that whole single part for the nozzle, and having a single tube that the filament sees is perfect, because in my experience the most common cause of the v6 failing was when the nozzle and the heat break weren't mated properly and plastic could slip out which caused a lot of jams and lost filament, which affected print quality severely. I most definitely will be buying one of these. Not to mention how many times the wires fell of the heater cartridge or thermistor because of the lack of strain relief, e3d really outdid themselves on this one
Very interesting stuff. After fiddling about with an Anet A8 for years I'm finally getting to the point where I want to just build a new printer & this ecosystem looks like a great option.
I've been using the Wham Bam Mutant toolchanger for about 4 months, this is an nice alternative to tool changers while maintaining direct drive extruder, perhaps this is the system I need!
One issue with abrasive filaments is that they also wear out heat-breaks eventually. When abrasion resistant Revo nozzles are available, they can include abrasion resistant heat-breaks that get swapped at the same time. I anticipate ObXidian nozzlebreaks will be following before too long. Having recently destroyed a hotend with a nozzle change recently, I can't wait to have one of these in my hands. It's a straight-up upgrade in so many respects (over a V6, or any other V6-ecosystem hotend). The previews from people who've had their hands on pre-production versions sound pretty amazing. They've been very engaged with the community (e.g. Voron devs have had their hands on these for a while), so everyone will be able to hit the ground running once they drop. It's so heartbreaking to see a Revo video that isn't accompanied by an interview with Sanjay.
Revo-Six: How do I connect the 2 cables from the Heatercore to my Prusa MK3S+ Einsyboard? The cables look very short, and the connectors are different too.
The fast heating would be beneficial for multiple extruders and standby temperature, if you switch nozzles the new one would heat up faster, thus reducing wait and total print time
Looks like a tool-less version of the mechanism already used by the Phaetus Dragonfly HIC HF (and significantly more expensive per nozzle-break). To that end they best be careful what they attempt to patent, as I'm pretty sure Phaetus won't sit idle after Slice went after the Dragon.
I swap nozzle sizes a lot - but on a TAZ that is the whole extruder and it is expensive!!! (and I have to cut the filament to do it etc ) - this would definitely be the way to go.
I will switch to this system once they offer a Nozzle-X equivalent. I HATE switching nozzles as I have to support the heater block with plyers. The plyers grip the same spot where the wires for the heater and the thermistors do their 90 degree bend. It also isn't so good for my thermal insulation. So glad there is a solution now. Looking forward to your review.
It would be interesting to see a h Nozzle/heartbreak that uses a standard (v6?) nozzle. So you could still quick change type or size of nozzles but when the nozzle wears out you just replace the nozzle instead of the whole heatbreak section. That way you could not only have swappable nozzle size, but type as well
Quick swap plus _finally_ an end to random leaks has me sold. I've lost too many days to de-gooping printers after the heatbreak backed out a little during a swap. But.. third-party offerings will be the key to success.
With the new heatcore have easy connectors for heater and thermistor and you can get the classic V6 heater and thermistor with the same connectors, it should be no problem to not only change the Revo nozzle quickly but also swap the heatcore to a V6 Heatblock with an hemera heatbreak. So with normal filament you can use the Revo nozzles and heatcore - and If you want to print abrasive filament, just unscrew the Revo nozzle, unplug the heatercore and screw in a V6 heatblock with a hemera heatbreak (or Clone...) and a NozzleX. I just installed a trianglelab V6-style coldend with hemera style heatbreak (trianglelab has this combination for quite some time now) just a month ago. This is quite interesting, as you get a good cloned heatblock, heater, thermistor and cloned hemera style heatbreak for about 20€. So I now only change a nozzle in case of a defect - normaly I only install a nozzle once and hottighten it - but have multiple hotend parts that I can simple unplug and unscrew in cold state. I mostly use one with CHT (for non-abrasive) and one with NozzleX. A bit less comfortable than the Revo system. But of course you can do this in combination with the Revo system. If you install the Revo and want to print abrasive, just remove the Revo nozzle and the core heater - and screw in a hemera heatbreak/Classic heatblock/NozzleX combination. At least for the time until e3d releases a Obidian-Revo nozzle... Trianglelab even has a ring-heater to screw in a heatbreak and a nozzle in the classic way... So changing to Revo do not affect flexibility. You still can use other nozzles quite easy - just buy extra hemera heatbreaks and use your existing V6 heatblock, heater and thermistor. For PID-tuning: even a silicon sock changes PID. Of course a different heater has a big impact in PID. But you can put correct parameters into gcode files and "print" them after changing the setup.
@@SwervingLemon 0.4 0.5 0.6 works all fine for me. but i often need a hardend nozzle. When this is aviable - its a nobrainer for me to upgrade my mk3s - eventually to hermea or microRevo
This is the first actually good, usable, user friendly and thought through nozzle solution I've ever seen. Sure, you can swap nozzles on, say, a Prusa but it's a pain in the butt. Gotta heat it, need wrenches, need pliers / a spanner to hold the heat block, there's always a risk of just snapping cables or leaving a gap and having plastic oozing etc... the old V6 is pretty primitive. This? This is straight up impressive and so much nicer to deal with. I have a 0.25 Nozzle X, but just having to go through the change work is discouraging me from swapping it in very often. Bravo, E3D, on making something actually user friendly and practical. Honestly, I have no problem paying £19 for these. However, ObXidian versions of these were mentioned in a video at some point, and those should be basically indestructible, so once I can get a full set of those, I'll be set. I also assume prices for this stuff comes down over time. This is just their initial release, E3D will absolutely also have nozzles in hardened steel, Nozzle X, ObXidian, you name it, but they gotta start somewhere.
The only thing I'm really not the biggest fan of is having the nozzle and heatbreak be completely inseparable, so if you get a jam in either one it is a total and complete pain to clean out. I've only had it happen one time in my beta unit, but it was a total pain to clear out.
I hope Revo also sees the system to be more of an improvement with 3rd party nozzles being a thing. Initially, they have to get their RnD costs back of course, but after that, I do hope they make the nozzles at the least open for 3rd parties.
Actually the Cetus nozzle has this concept with the nozzle and the heatbreak being one piece. Although it has other problems this eliminated several points of failure. Funny part: I now swap the Cetus extruder for a Hemera with V6 system :) Not for the hotend but for the filament mechanics obviously.
A rapid-change title with three different edits in the first half hour, sometimes I wonder if that's for SEO purposes or if that's just a case of inspiration striking :)
One thing which would have made the new system perfect is a separate heatbreak which standard V6 nozzles could screw into, with appropriate flats for hot tightening. Then E3D would only need to make one heatbreak instead of all the different nozzle breaks, and you could set them up with exact nozzles you want to swap out. It would lower cost through the transition to the new system and give more choice of nozzles. I wonder if the lower section of the nozzle break is large enough to cut a V6 thread into, that would make it pretty easy. If not then you would just need essentially an extended heatblock on the bottom of the heatbreak. It would have the drawbacks of higher mass and probably lower performance and reduce the Z build height (also requiring a nozzle recalibration, possibly even moving the Z limit switch) but I think it would essentially be like a V6 in performance with swappable nozzles and quick change, acting as a transition to the newer ecosystem. Either E3D or a 3rd party should look into this I think. Also, I was lucky enough to get an E3D golden ticket earlier this year so I will be getting my hands on a revo early. I had the choice between the Revo Six, Revo Hemera and Revo Micro and I went for Micro even though the Hemera comes with a whole extruder. I will be incorporating the micro into my AM and material science masters project and need something very lightweight.
You can actually tweak the expansion coefficient of a ceramic with specific ceramic mixes there is even ceramics that contract with temperature increase due phase transition. So it is just trial and error and some books are all you need to develop a ceramic that has the same expansion coefficient as copper
the Mosquito isn't the only hotend that allows for wrenchless nozzle changes, I got mine (Tr*angleLabs Dr*gon) for about $100 with thermistor and heater cartridge.
This reminds me a lot of the OmniaDrop with the circular heater. I have been a big fan of the Nozzle X and am surprised they didn't include a better nozzle at this price. Will be interesting to see how this works out
Gute Besserung! Ineresting idea to put heater and sensor closer together. When the sensor gets its data more acurate and faster, it's possible to keep the heatblock smaller. That might be positive on lower printhead weight. The con might be you need more ampere to heat the thing up fast. The second con: You are bound to a manufacturer. (manufacturer lockin) Another problem is that hemera is allready a new system and people payed a lot of money for it just to see that BTTR released a "better" system a few weeks later (BIQU?). For me it's a reason to wait. I think there will be no real inovations from E3D anymore.
The Dragon also can be torqued down, I'd realy love to see groove mount die in anycase (or rather be optional vs screw mount). Looking forward to your full review, really curious about temperature acuracy since the thermistor comes before the nozzle
If they can mass produce these to lower the cost I would happily order some. Until then, I can change a nozzle in a couple minutes with some pliers and that is fine. The features are certainly worthy as a v6 successor
Cool video. Definitely want to see how easy it will be to put the new E3D REVO on the PRUSA mk3s. I have always wanted to try other nozzle sizes but after breaking my heat bread once I didn't want to try again. If you can really just replace the nozzle every print without tools I know I will go and upgrade.
Really looking forward to reviews, for me the big thing is the quick change, having only a single printer and doing very different types of project, being able to change nozzle makes a huuuge difference and worth the price. Though, really hope they come out with a nozzle X / obsidian version soon.
Brilliant design. I think it quite possible my Ender 5 Pro will have to have the Revo Hemera at some point in the new year. As always thanks for the great review, Tom. Prosit Neujahr
I'm not entirely sure how you're going to 'quick swap' your nozzle if you've left the filament in from the previous print. Yeah you could heat it up to remove the filament, and then burn your fingers while quickswapping...
I'd love to hear where you think the Rapido falls on the hotend spectrum. I just got one and I'm so far impressed. Currently designing a Prusa+orbiter mount for it.
Once they have the hardened (diamond-like coating) nozzles they have said will be coming, the nozzle-break price becomes less of an issue, as nozzles will cease being consumables for most people. For me, I'd pay quite a lot for the easy nozzle change. I learned my lesson recently where I was having print quality issues and was trying to do everything I could to avoid doing a nozzle swap. Eventually, when I did do a swap (and saw how both my nozzles were about 2mm shorter than when new) the improvement in print quality was near miraculous. However, in the process, I damaged a thermistor and had to buy and wait for a new one. Again, emphasizing the value of the Revo. I do find it a little strange how people expect nozzles to cost a few dollars, while spending hundreds on filament. Even at the current Revo nozzle-break cost, once divided by the number of spools run through each nozzle (assuming it's just printing normal PLA) the nozzle cost will be tiny compared to the filament.
is the hemera revo heatsink different to the origional hemera heatsink other than the bit htat the spring sits against? it doesnt seem like it, why would i spend 50 pounds on a new heatsink that is virtually identical?
this would be fantastic if you switch between 3.0mm and 1.75mm filament often. On my printer now, I need to swap out 2 extruder gears, the throat, the nozzle, the ptfe between them and the extruder, etc. If the top bit is thic enough you could just have a different nozzle / throat assembly you swap and you're good (I mean apart from extruder)
It seems to me like 3mm is dead 😞 as somebody who's stuck with a 7+ year old i3 I find it increasingly hard to find 3mm filament in stock, and 3mm hotend/extruder options are also very limited.
I have had SO MANY PROBLEMS with leaks from the nozzle or heat break not being properly seated on my Micro Swiss direct drive setup. My printer's been down for two weeks because I basically wrecked a heatsink and was too broke to afford a new one. The thing that really, really excites me about this (and the Prusa XL) is the way it eliminates so many of those connexions. I don't care about the quick-swap, though that's very cool. I'm just happy to see it reduce a point of failure.
Since the XL has the same feature that I care about, I'm feeling confident that either E3D is willing to license this at reasonable rates, or else that the "single piece nozzle and heat break" isn't part of the patent. Either way, I'm very happy to see this innovation come along and I'm sure that in the near-ish future we'll see plenty of options.
Now I have to go do some research and figure out how I'd mount one of these on an Ender 5 with direct drive...
I'm thinking about getting the Hemera for my crappy Anet A8. All it takes is a new printed mounting plate, some wire work, and a firmware update.
@@hazonku I fitted a Titan Aero to my Anet A6 3 years ago and it greatly improved the quality (as well as upgrading the electronics and drivers), the Hemera should be even better and easier to mount.
9:00 actually, the heated bed on the E3D toolchanger I use at work reaches 80°C faster than the 40 or 50 W hotend reaches 270 °C. And for toolchanging, faster heating times is a very welcome improvement.
Also with the XL on the way I bet we see more segmented beds on the market and those will heat up faster
Seems risky to heat up a bed that rapidly. Over time it is much more likely to permanently warp the bed.
@@jvandervyver bed warping seems to be an issue of a bed that is not allowed to expand when heated. In my setup, warping is no problem.
Adoption is always the biggest issue with any new system. Given E3D's track record, I think it will only be a matter of time before everything is sorted out and we get 3rd party components.
Sanjay would pat you on the back and say thank you for buying the clone.
It looks like they did open up part of it for 3rd party use. They patented half the assembly, allowing 3rd party nozzles to use their attachment. The only part they cant use from the sounds of it is anything below the thread. Joel over at 3dprintingnerd posted an interview with e3d and they briefly covered it.
Are there 3rd party ones yet?
Dynamic temperature changing would be great for supports. PETG in particular has crap adhesion if it's printed cold, so it would be ideal for zero-gap supports using a single nozzle.
Thanks for the video. I switched from .4 to .6 mm nozzle a year ago, and I have never looked back. I mostly print functional parts, and so far a .6 nozzle serves me well. It's not that much rougher than a .4 mm, and I find the print settings to be more important.
I'm in a similar boat as you. I found stronger parts, much quicker prints and the once you dial in your support settings, you are all set!
For me the almost absolute safety of the heater is one of the best innovations for 3D printing and it’s not talked about much.
Of the 4 times I've ever attempted to swap nozzles on my v6, I ended up bending my heatbreak twice, got the nozzle permanently stuck inside my T wrench once, broke my thermistor wires once, and burned myself just about every single time. If this nozzle is even SLIGHTLY better, while still being the same form factor, I'd fork down $200 for it right now.
Got my preorder.
It's amazingly simple to change the nozzle.
@@mykehdoom That's what I wanna hear!! I've got pre orders in for two of them, placed shortly after making that comment. Congrats!
Worth every penny. V6 the poo poo
Unless this had significantly improved performance over my V6, I don't see a reason to to upgrade. Honestly never had an issue swapping out my nozzles, and the broad compatibility of 3rd party nozzles has been a huge benefit to me. I'd like to see you throw this on your Voron and see if the quick-change functionality has improvements to your general workflow.
yea same here. Well ecept I kinda brutforce tightend my nozzle and riped out my threads. But that bs is totaly on me.
@@Jimmy90001 "I've never had an issue swapping out my nozzles. (Except of course the fact that I destroyed my heatblock swapping out my nozzle)"
I've had to deal with two leaks in the past year, and they have put me off changing nozzles as frequently as I'd like. That quick change system is the biggest plus to me.
But I'm also interested in seeing the throughput of the Micro can keep up in faster prints, now that you'd have decreased mass up top. Same with the Hemera, seeing as I'd be between one of those two.
It just makes swapping nozzles so much easier and quicker, though. To the point where I can pretty much decide on a per-print basis whether I need the fancy 0.25mm nozzle for a detailed print, or a 0.8mm nozzle for a quick and dirty functional print. Unscrew one, shove the other one in, done. I don't have trouble swapping nozzles either, but it's still a 10-15 minute job between finding nozzles/wrench and switching them out and hot-tightening and re-zeroing the Z axis on the printer and all that.
About the only disadvantage is price, but I'm sure the Aliexpress clone machine is working overtime copying this system right now if you're cheap.
@@AndrewAHayes I find the price quite affordable save the nozzles. But I'm not getting it day-one. I'm going to wait for a Nozzle X or similar first. I haven't had to replace mine in over a year, so it's a one and done for me.
Normally never pre-order things, but this was an exception. Planning on being done with my Voron 2.4 around March, so perfect timing for me.
(low risk) Physical things aren't really included with that sentiment. Video games on the other hand have pretty much infinite supply.
Got one for my voron 2.4 350mm as well. Going to partner it with the stealthburner
Honestly, nozzle-swapping was one of the appeals to Mosquito for me; having multiple V6-styles (all original, saying style because some is hemera/other sinks like prusa), the block rotating along right as you can't find a vice or so is a nightmare. The whole concept of the circular "pcb-style like our beds" heater is also interesting, it might lead to some very interesting nozzle/hotend designs especially in high flow/multi-colour/mixing stuff (imagine 3 extruders, 1 nozzle/heater, and mixing filament like you'd mix ink on an inktjet, using the whole adaptive pressure stuff we got to make some cool stuff)... Also, this nice way of swapping might make multi-extrusion width in one print without toolchanging MUCH easier. 0.4 for detail, and then 0.8 or larger for the big stuff layers (some of my models defo could use that)
So a nozzle changer for your tool changer, that would be interesting. Perhaps as one colour hotend is cooling down for a nozzle change, it could print other colours in the meantime or whatever.
I'm curious how and if this will succeed, especially in terms of the patents and how E3D will be dealing with 3rd party manufacturers willing to make Revo nozzles.
Looking at the pattents i believe they are more on the core heater technology. I also imagine them them willing to liscense their tech at a reasonable rate considering their past behavior with other organizations they have partnered with in the past.
The approach I'd recommend is for E3D to assign their Revo patents to a suitable open patent alliance AFTER their next generation system has been in the market for a while. E3D has proven their support and approval of clones and to improve low-end printers, but there is no need for them to cannibalize their own business to do so. A delay of one generation should strike a good balance.
Lol, patents.
I would think E3D doesn't want crappy clones, like what has happened with V6 and nozzles. Complexity of a nozzle block alone could limit some of that.
I believe the 'Nozzle-break' with a heatbreak integrated into the nozzle was already patented and then the patent was abandoned, I don't know the exact patent number it was I looked at. So I think E3D couldn't patent the nozzlebreak even if they tried.
I pre-ordered the micro. Will put in my coming Stealthburner upgrade on the Voron 2.4. I was always too lazy to swap nozzles on my printers, but with this system I see myself switching from 0.4 to 0.8 pretty often. I hope they bring the nozzle-X in the future, that's their current king for the V6, so maybe the same thing for the Revo.
Likewise, I really don't mind them wanting to earn money on this product, they gave so much already in giving out the V6 design for everyone. Hopefully they will license some things out to other manufacturers, so we get more choices. Don't be like Slice engineering, cause F them.
I just put mine on an Ender 6. It is the best upgrade I have ever done. It bolts right on and works. Changing the nozzle is fantastic. Go from draft to quality print in under a minute. I can print fast with better quality. I wish I did it soon, great job guys.
What I'd like to see is an adapter nozzle for the quick swap system, which let's you install a standard nozzle onto a quick swap part. The heat transfer wouldn't be as perfect, but the ability to not only take advantage of the hand-tightening quick swap ability, as well as being able to retain use of your specialty nozzles, such as the CHT, would make it worth the downsides.
I believe they have this now on the MK4. (If I've understood you correctly)
Heater block are round; Pie are square.
Jokes, aside... Good news, no more breaks in the assembly (nozzle, meltzone, heatbreak, PTFE shaft) where a lot filament jams. Bad news: Nozzle wears out, you have to replace the whole filament assembly (more cost)
You perfectly summed up what is holding me back from getting Revo now. High temps and harder than brass nozzles are a must. Thanks for the look through!
I’m excited for this system! I maybe have a need to print in a larger nozzle size once in a blue moon - but I always put it off because I really dislike the process of a current nozzle swap. I’m sure I’ll print more aggressively in different nozzle sizes after this.
It’s also a big win in terms of accessibility - yet to see how it has handles, but I can imagine this will only make swapping nozzles easier for people with limited mobility.
If I were teaching my nieces to do a nozzle swap, this product would be a great place to start. Thanks for the video!
@Thomas: if you haven't already, would love to see how you get on upgrading the Mk3(whatever revision) to support the Revo Six - I envision connector "additions" on the hot-end/extruder cabling, and maybe some "light fighting" to get the Noctua fan working, but otherwise it then becomes plug 'n' play...
Great review, as ever Thomas, thanks! Been looking forward to these coming to market since I first had a look and feel at TCT Oct 2021. The ease of nozzle swap is such a nice feature even/especially if only used occasionally - it works every bit as easy you show and totally removes the faff involved with height offset recalibration vs a threaded nozzle; great to see E3D continue to set the pace in evolving extruders - they really are beautifully engineered products.
That heater core is pure genius!
I am one of the Beta testers for this hotend system. Before this, I bought 5x copies of the v6 hotends just to avoid doing nozzle changes (I do not like the risks of burning my self, damaging the nozzles, not getting it tight enough etc) when I want to either use a smaller or larger nozzle (in 1.75 filament I had 0.2, 0.4 and 0.8mm nozzles, and for 3mm filament I had 0.4 and 0.6mm - I made a quick swap system to swap between 1.75mm and 3mm filament - though it requires a printer restart). For this, having the Revo quick swap nozzles are great (no need to restart printer, just cool it down, swap and heat it up).
That said, this system is not for everyone: rewiring of printers that does not have the right connectors; high temp printing or printing with abrasive filaments. If you also need high flow rates, this will struggle (simple physics on how fast the heat can be transferred to the filament).
However for users that want a simple way to change nozzles, this is a great system (note that a couple of companies are working on different ways to solve this, so go check them out also). No special tools, no extra procedures (like hot tightening) etc. just simply unscrew it by hand, and screw the new one in by hand. Also the heatup times are fantastic. I typically print on diluted wood glue (spread over glass), which means that I preheat the bed for quite a while (to dry the wood glue), while still slicing and figuring out all the print settings. As soon as I am ready, I heat the nozzle and is printing within a minute. Also the small size of the heater means it cools very quickly (once power is removed).
An extra note, the Revo Micro uses a 5v fan on its heatsink - this makes it a bit harder to install on some printers. While it comes with a step down converter, it have to be installed correctly. The fan is also a 25mm one (replacements are hard to find).
For cooling fan shrouds, adjustments may be required coming from the v6.
According to the E3D website, they will start shipping in March 2022. Holy moly that's nuts.
LOVE my Revo!!! Changing nozzles ALL the time and its effortless. Never a chance of leaks woot
LOVE the new REVO ecosystem. This is what 3d printing really needs! This makes one of the most frustrating parts of maintenance significantly easier. The PTC aspect of this heater is one of the most interesting to me! It will make the systems MUCH more stable. I figure we may have a specific high temp REVO like you said. I will be curious to see what that top end temp looks like!
Nice but I will wait for the hardened nozzle version
I would like to say Thank you to E3D for sending this to you , also thank you for the look ahead on this increadable product . I am really looking forward to being able to buy the full package when it becomes available . If this works as it looks like it will it will solve alot of problems before they happen .
The fact I don't have to fenangle my way around a 280 degree lump of metal to change a nozzle is worth the price. I love using different nozzles on my MK3 but the leak chance always puts me off. I hope they release a hardened revo nozzle. or a Nozzle X
my biggest headache with my MK3s was incorrectly changing out my V6 nozzle. didn't get it tight and had leaks which lead to a whole bunch of other issues - including thermal melting of the extruder parts and complete rebuild. Short response - Revo appears to be a simpler system so that I could change nozzles reliably - or maybe I should just gain more experience changing my V6 nozzles!
Hear, hear. I loathe having to risk working on a "hot" hotend. And I've had to deal with two leaks so far, it's not a fun time.
This.
As someone who relies on my printers for my income, the Hemera is awesome, but can be prone to leaks between the nozzle and heatbreak which is a constant worry when printing 24 hours a day, 7 days a week. Super excited for the Revo.
How would the "fenangle around a 280 degree lump of metal" change? It's ceramic now, granted, but that nozzle is still jammed right up against the heater block, and the OD of the "ring" of the nozzle is smaller than that of the heater. Meaning it's pretty much impossible to grab and turn that nozzle without touching the heater or its sock.
Edit: Typo
@@pr0xZen You don't have to do it hot anymore. You can do it cold, at room temperature. The heat break and the nozzle are a single assembly, unlike the V6.
I am a bit cricitcal regarding the PID tuning. Why should the PID parameters stay the same? It has a way different thermal mass, even though the thermistor is the same
a conservatively tuned pid loop should work reasonably across quite a range of heaters, so it is likely that the new hotend will work with no tuning... but yes, i'd recommend tuning it anyway.
You really want to make a Pid tune. If you don’t, you won’t get the full potential of the heating element.. or it will unnecessarily over and undershoot.
You think that's bad?
The heater block is supposed to be self regulating. Have fun tuning that PID, where the reaction of the heatblock is totally non-linear to the power applied.
@@pontiacg445 If you´re right.. how should this heater work then with the non-changed PID from the previous heater? Magic?
@@randomname3894 Not approaching the max temp, where the cartridge starts to "self regulate" by increasing it's resistance.
And as I'm pretty sure was covered in the video, using the same PIDs is probably "good enough." So yeah, I guess magic.
Can't wait to see if someone creates an adapter for V6 nozzles to be used on the Revo
Nice overview! I agree on the 0.6 mm being the better option for most of my prints.
Im excited for this and not even because of the rapid nozzle change, because it eliminates torquing nozzles and leaking plastic between nozzles and heatbreaks.
I ordered mine earlier today before this video came out mainly because it makes it much easier to change nozzles hopefully without blockages. I have not experimented with various nozzles size just because of the issues I had with blockages.
for mating, they heat up the brass most likely so it expands just enough for the steel core to slide in, and when it shrinks it forms a very strong interference fit with it most likely
Having a hardened steel nozzle is going to be a must for CF and other specialty filaments.
For those nozzles you can do everything on a 2 axis lathe. Hex heads etc are no problem at all
I hope there's going to be a hf version soon. Flow wise, the revo really just can't compete with hotends like the dragon and rapido for the same or lower price.
A bondtech CHT version would also be good
Agree 100% with your comments Tom. I think it could possibly be a nice upgrade from a V6 if you're starting a new printer build but for me it's not worth upgrading my perfectly reliable current setup with tons of options from various manufactures.
Interesting, I was going to upgrade to a Hemera with: a titanium heatbreak, plated copper heater block, 40W high precision heater cartridge, PT1000 Temp sensor and a Nozzle X nozzle. But you're right Tom, I don't really *NEED* all that, a Revo Hemera will probably be more than capable for my use case, but they (Revo Hemera vs Fully Upgraded Hemera) cost basically the same
Ultimaker swappable cores are £100. (S5 anyway). The Uktimaker is amazing because it can easily print any material (bar peek etc) but at a cost and you can’t even swap nozzles - u need to replace the whole print core every time.
This really enables home printers to experiment cost effectively with all kinds of materials and nozzle sizes. Hobbyists should love this as they can learn much more about printing, and much more about materials and their applications
I like the look of that. I often Want to change the nozzle but don't because it's a pain.
Hi Thomas. E3D says it is a drop in replacement for V6 assembly but what about the PTFE tube there is on Prusa extruders ? Doesn't the length of the Revo nozzle alter the length of the ptfe tubbing ?
Tom: The Revo heater is rated at 40W. The V6 was only 30W. The new heater also wraps around (what is now) a very small heater block. I've ordered a Hemera with a full set of nozzles. I can't wait to try it with some of the larger sizes on my Prusa Mk3s.
Im really excited for the revo. I hope they release a direct upgrade kit for the Prusa i3 (with the correct calbes).
Ain't the Revo Six exactly that? Or does the i3 not have those connectors at the hotend?
@@Kalvinjj Yeah, for some reason Prusa decided to run all the cables in the hot end all the way back to the electronics box. As a result, the shorter connectorized cables won't fit on a Prusa i3 printer. Though, instead of a separate SKU of the whole assembly with longer cables, I think a cable extension accessory would be a better product.
@@Sembazuru Eh that's kinda annoying then... I agree about a cable with connectors at the end (for everything: heater, thermistor, fans and probe) being a nice idea.
Given that I have the crimping tools my bet if I was in that situation would be to cut the cables and add the connectors, but I understand that not everyone has the tool and a bunch of connectors waiting for use (heck I might not have the perfect one either...).
Just as a note with Hemera, The new nozzles might fit in the original Hemera but you actually need a new Revo specific heatsink for it to work correctly.
So negative from my side of view: First, you can not use 3rd party nozzles anymore, only original. Since you can get nozzles dirt cheap, this is one thing that will increase the printing price. Second, integrating everything like with the combined nozzle means a) you need specific, most likely patended replacement parts, and b) you throw away parts that still work.
And one year later there’s a plethora of Chinese clones of the revo nozzle (including a titanium one for use with abrasive materials)
@@sterkriger2572yeah I figured there would be.. honestly maybe rather than lamenting the use of normal nozzles more people should adapt. The thing is... I couldn't see many people actually using it.
that whole single part for the nozzle, and having a single tube that the filament sees is perfect, because in my experience the most common cause of the v6 failing was when the nozzle and the heat break weren't mated properly and plastic could slip out which caused a lot of jams and lost filament, which affected print quality severely. I most definitely will be buying one of these. Not to mention how many times the wires fell of the heater cartridge or thermistor because of the lack of strain relief, e3d really outdid themselves on this one
Very interesting stuff. After fiddling about with an Anet A8 for years I'm finally getting to the point where I want to just build a new printer & this ecosystem looks like a great option.
Great points about .6 nozzles! Agree 💯
I've been using the Wham Bam Mutant toolchanger for about 4 months, this is an nice alternative to tool changers while maintaining direct drive extruder, perhaps this is the system I need!
One issue with abrasive filaments is that they also wear out heat-breaks eventually. When abrasion resistant Revo nozzles are available, they can include abrasion resistant heat-breaks that get swapped at the same time. I anticipate ObXidian nozzlebreaks will be following before too long.
Having recently destroyed a hotend with a nozzle change recently, I can't wait to have one of these in my hands. It's a straight-up upgrade in so many respects (over a V6, or any other V6-ecosystem hotend). The previews from people who've had their hands on pre-production versions sound pretty amazing. They've been very engaged with the community (e.g. Voron devs have had their hands on these for a while), so everyone will be able to hit the ground running once they drop.
It's so heartbreaking to see a Revo video that isn't accompanied by an interview with Sanjay.
Revo-Six: How do I connect the 2 cables from the Heatercore to my Prusa MK3S+ Einsyboard?
The cables look very short, and the connectors are different too.
Just ordered mine, cant wait to get my hands on it
The fast heating would be beneficial for multiple extruders and standby temperature, if you switch nozzles the new one would heat up faster, thus reducing wait and total print time
I'm excited to see the variations that will come, hardend steel, copper, olsen ruby etc.
(Hopefully)
Looks like a tool-less version of the mechanism already used by the Phaetus Dragonfly HIC HF (and significantly more expensive per nozzle-break). To that end they best be careful what they attempt to patent, as I'm pretty sure Phaetus won't sit idle after Slice went after the Dragon.
I swap nozzle sizes a lot - but on a TAZ that is the whole extruder and it is expensive!!! (and I have to cut the filament to do it etc ) - this would definitely be the way to go.
I will switch to this system once they offer a Nozzle-X equivalent. I HATE switching nozzles as I have to support the heater block with plyers. The plyers grip the same spot where the wires for the heater and the thermistors do their 90 degree bend. It also isn't so good for my thermal insulation.
So glad there is a solution now. Looking forward to your review.
Excellent review! I look forward to when you try it out! Thanks, Tom!
It would be interesting to see a h
Nozzle/heartbreak that uses a standard (v6?) nozzle. So you could still quick change type or size of nozzles but when the nozzle wears out you just replace the nozzle instead of the whole heatbreak section. That way you could not only have swappable nozzle size, but type as well
Quick swap plus _finally_ an end to random leaks has me sold. I've lost too many days to de-gooping printers after the heatbreak backed out a little during a swap. But.. third-party offerings will be the key to success.
With the new heatcore have easy connectors for heater and thermistor and you can get the classic V6 heater and thermistor with the same connectors, it should be no problem to not only change the Revo nozzle quickly but also swap the heatcore to a V6 Heatblock with an hemera heatbreak.
So with normal filament you can use the Revo nozzles and heatcore - and If you want to print abrasive filament, just unscrew the Revo nozzle, unplug the heatercore and screw in a V6 heatblock with a hemera heatbreak (or Clone...) and a NozzleX.
I just installed a trianglelab V6-style coldend with hemera style heatbreak (trianglelab has this combination for quite some time now) just a month ago. This is quite interesting, as you get a good cloned heatblock, heater, thermistor and cloned hemera style heatbreak for about 20€. So I now only change a nozzle in case of a defect - normaly I only install a nozzle once and hottighten it - but have multiple hotend parts that I can simple unplug and unscrew in cold state. I mostly use one with CHT (for non-abrasive) and one with NozzleX. A bit less comfortable than the Revo system. But of course you can do this in combination with the Revo system. If you install the Revo and want to print abrasive, just remove the Revo nozzle and the core heater - and screw in a hemera heatbreak/Classic heatblock/NozzleX combination. At least for the time until e3d releases a Obidian-Revo nozzle...
Trianglelab even has a ring-heater to screw in a heatbreak and a nozzle in the classic way...
So changing to Revo do not affect flexibility. You still can use other nozzles quite easy - just buy extra hemera heatbreaks and use your existing V6 heatblock, heater and thermistor.
For PID-tuning: even a silicon sock changes PID. Of course a different heater has a big impact in PID. But you can put correct parameters into gcode files and "print" them after changing the setup.
I feel like Tom Hanks in Big. The part where he raises his hand, and says "I don't get it" over and over.
I was thinking about eraly acess preorder (had a mail today) but i will wait for a harder nozzle like the nozzle x.
That was my first thought. I'll buy that kit the moment they offer a .5 nozzle X for it.
@@SwervingLemon 0.4 0.5 0.6 works all fine for me. but i often need a hardend nozzle. When this is aviable - its a nobrainer for me to upgrade my mk3s - eventually to hermea or microRevo
This is the first actually good, usable, user friendly and thought through nozzle solution I've ever seen. Sure, you can swap nozzles on, say, a Prusa but it's a pain in the butt. Gotta heat it, need wrenches, need pliers / a spanner to hold the heat block, there's always a risk of just snapping cables or leaving a gap and having plastic oozing etc... the old V6 is pretty primitive. This? This is straight up impressive and so much nicer to deal with. I have a 0.25 Nozzle X, but just having to go through the change work is discouraging me from swapping it in very often. Bravo, E3D, on making something actually user friendly and practical. Honestly, I have no problem paying £19 for these. However, ObXidian versions of these were mentioned in a video at some point, and those should be basically indestructible, so once I can get a full set of those, I'll be set. I also assume prices for this stuff comes down over time. This is just their initial release, E3D will absolutely also have nozzles in hardened steel, Nozzle X, ObXidian, you name it, but they gotta start somewhere.
The only thing I'm really not the biggest fan of is having the nozzle and heatbreak be completely inseparable, so if you get a jam in either one it is a total and complete pain to clean out. I've only had it happen one time in my beta unit, but it was a total pain to clear out.
I hope Revo also sees the system to be more of an improvement with 3rd party nozzles being a thing.
Initially, they have to get their RnD costs back of course, but after that, I do hope they make the nozzles at the least open for 3rd parties.
I ordered the Revo Hemera yesterday. This should be fun
Actually the Cetus nozzle has this concept with the nozzle and the heatbreak being one piece. Although it has other problems this eliminated several points of failure. Funny part: I now swap the Cetus extruder for a Hemera with V6 system :) Not for the hotend but for the filament mechanics obviously.
A rapid-change title with three different edits in the first half hour, sometimes I wonder if that's for SEO purposes or if that's just a case of inspiration striking :)
One thing which would have made the new system perfect is a separate heatbreak which standard V6 nozzles could screw into, with appropriate flats for hot tightening. Then E3D would only need to make one heatbreak instead of all the different nozzle breaks, and you could set them up with exact nozzles you want to swap out. It would lower cost through the transition to the new system and give more choice of nozzles.
I wonder if the lower section of the nozzle break is large enough to cut a V6 thread into, that would make it pretty easy. If not then you would just need essentially an extended heatblock on the bottom of the heatbreak. It would have the drawbacks of higher mass and probably lower performance and reduce the Z build height (also requiring a nozzle recalibration, possibly even moving the Z limit switch) but I think it would essentially be like a V6 in performance with swappable nozzles and quick change, acting as a transition to the newer ecosystem. Either E3D or a 3rd party should look into this I think.
Also, I was lucky enough to get an E3D golden ticket earlier this year so I will be getting my hands on a revo early. I had the choice between the Revo Six, Revo Hemera and Revo Micro and I went for Micro even though the Hemera comes with a whole extruder. I will be incorporating the micro into my AM and material science masters project and need something very lightweight.
I don't think I will take the jump until a Nozzle X version for the Revo comes out.
You can actually tweak the expansion coefficient of a ceramic with specific ceramic mixes there is even ceramics that contract with temperature increase due phase transition. So it is just trial and error and some books are all you need to develop a ceramic that has the same expansion coefficient as copper
the Mosquito isn't the only hotend that allows for wrenchless nozzle changes, I got mine (Tr*angleLabs Dr*gon) for about $100 with thermistor and heater cartridge.
This reminds me a lot of the OmniaDrop with the circular heater. I have been a big fan of the Nozzle X and am surprised they didn't include a better nozzle at this price. Will be interesting to see how this works out
Smaller than a V6 is a big plus for me. I have mainly stayed with J-heads for the small size and weight.
I’d like to see that nozzle holder with a clip tight lid too stop dust and debris contamination.
Love your videos, thank you for all your knowledge and fairness when testing products
I will be upgrading to the Revo, just waiting on the Obxidian build :)
Gute Besserung!
Ineresting idea to put heater and sensor closer together. When the sensor gets its data more acurate and faster, it's possible to keep the heatblock smaller. That might be positive on lower printhead weight. The con might be you need more ampere to heat the thing up fast. The second con: You are bound to a manufacturer. (manufacturer lockin) Another problem is that hemera is allready a new system and people payed a lot of money for it just to see that BTTR released a "better" system a few weeks later (BIQU?). For me it's a reason to wait. I think there will be no real inovations from E3D anymore.
The Dragon also can be torqued down, I'd realy love to see groove mount die in anycase (or rather be optional vs screw mount). Looking forward to your full review, really curious about temperature acuracy since the thermistor comes before the nozzle
Very interesting. Hope to see your in depth review soon.
If they can mass produce these to lower the cost I would happily order some. Until then, I can change a nozzle in a couple minutes with some pliers and that is fine.
The features are certainly worthy as a v6 successor
Cool video. Definitely want to see how easy it will be to put the new E3D REVO on the PRUSA mk3s. I have always wanted to try other nozzle sizes but after breaking my heat bread once I didn't want to try again. If you can really just replace the nozzle every print without tools I know I will go and upgrade.
Really looking forward to reviews, for me the big thing is the quick change, having only a single printer and doing very different types of project, being able to change nozzle makes a huuuge difference and worth the price.
Though, really hope they come out with a nozzle X / obsidian version soon.
A CHT Revo would be the ultimate nozzle. I would have to build a Voron for it.
Brilliant design. I think it quite possible my Ender 5 Pro will have to have the Revo Hemera at some point in the new year. As always thanks for the great review, Tom. Prosit Neujahr
Really looking forward to seeing your flowrate and other stats testing!
Yeah, would be great if they sold the heater core with the nozzle in separate, because their hemera upgrade is a bit salty on the price
I'm not entirely sure how you're going to 'quick swap' your nozzle if you've left the filament in from the previous print.
Yeah you could heat it up to remove the filament, and then burn your fingers while quickswapping...
Lol underrated comment. Your absolutely right!
You can just snip the filament and the next time you're using that nozzle just pull it.
@@kickassnetwork just pull it out? Lol you have to heat the nozzle up to get it out.
@@HDCamcord yeah, thus I said the next time your using it. Since you'll have to heat it up anyway when you next use it.
I'd love to hear where you think the Rapido falls on the hotend spectrum. I just got one and I'm so far impressed. Currently designing a Prusa+orbiter mount for it.
Once they have the hardened (diamond-like coating) nozzles they have said will be coming, the nozzle-break price becomes less of an issue, as nozzles will cease being consumables for most people.
For me, I'd pay quite a lot for the easy nozzle change. I learned my lesson recently where I was having print quality issues and was trying to do everything I could to avoid doing a nozzle swap. Eventually, when I did do a swap (and saw how both my nozzles were about 2mm shorter than when new) the improvement in print quality was near miraculous. However, in the process, I damaged a thermistor and had to buy and wait for a new one. Again, emphasizing the value of the Revo.
I do find it a little strange how people expect nozzles to cost a few dollars, while spending hundreds on filament. Even at the current Revo nozzle-break cost, once divided by the number of spools run through each nozzle (assuming it's just printing normal PLA) the nozzle cost will be tiny compared to the filament.
There's a similar system already available from a company in the Czech Republic. I can't remember the company name though.
3:18 maybe for you but people using and reviewing in beta is really nice for development and finding any issues you didn't think of or catch.
is the hemera revo heatsink different to the origional hemera heatsink other than the bit htat the spring sits against? it doesnt seem like it, why would i spend 50 pounds on a new heatsink that is virtually identical?
I wish there were chapter markers so I can watch in segments and come back to it quickly.
thanks for the review, was really curious to learn more about these and am looking forward for the actual test! merry xmas!
They need to develop hardened steel nozzles for those that are printing with abrasive filaments.
That strain relief should have been standard in the 3DP community YEARS ago. Very nice content, Tom.
this would be fantastic if you switch between 3.0mm and 1.75mm filament often. On my printer now, I need to swap out 2 extruder gears, the throat, the nozzle, the ptfe between them and the extruder, etc. If the top bit is thic enough you could just have a different nozzle / throat assembly you swap and you're good (I mean apart from extruder)
It seems to me like 3mm is dead 😞
as somebody who's stuck with a 7+ year old i3 I find it increasingly hard to find 3mm filament in stock, and 3mm hotend/extruder options are also very limited.
