Are you not concerned that the Teflon tape insulated the CHT nozzle and prevented it from performing at its full potential?

[@sail4life]

Fess up, you know you want one...

[@jasperbarnett6819]

Yeah this continues to demonstrate why I have no plans to ever "upgrade" to Revo. I can get a hardened steel CHT nozzle today, and I still don't see the benefit of rapid nozzle changes as someone who is MAYBE using his printer 25% of the time, so just having a wear resistant 0.4mm nozzle is really all I need. Especially since so much of what I make is structural parts, where printing fast can be a really bad thing for part strength, I'll happily trade the 50% longer print times for just knowing that my printer will happily handle everything from PLA to carbon filled PC with zero issues...

[@ericlotze7724]

It would be nice in my opinion, but between the Closed Source Nature, and like you said how an abrasive resistant 0.4mm (or whatever your “standard nozzle size” is) nozzle will work 75% of the time, I don’t see much of a need there.

[@spindlywebs]

that's also what I'm interested in, though I've heard larger nozzles actually make stronger parts? like what if you printed 0.8 on PAHT-CF or GF-PC? that's what i want to know 😭

[@theglowcloud2215]

cool story

[@dn275]

I still don't understand the sales pitch for this system. Nozzle changes are already easy and quick. Nozzle choice is limiting. How often and for what reason is there to change nozzles often enough to warrant locking yourself into this ecosystem? I see it being aimed at people who are new to 3D printing and selling them on the simplicity. Even then, is unscrewing something and screwing something else in that high of a bar?

[@jasperbarnett6819]

@@dn275 I guess people have issues with stripping their heater blocks or bending the heat brake when hot tightening? But like, that can be much more easily solved by just using a copper block and adding a couple screws through the block and into the heatsink, Mosquito-style... Or just by not over-tightening the nozzle... There are even PRINTABLE TORQUE WRENCHES that folks have designed for exactly this purpose. I honestly don't understand the Revo hype when I could just get a Mosquito, with better performance, full compatibility with any of my old nozzles, a higher max temperature, and only VERY marginally more difficult nozzle swaps (oh no I'll need to get a socket wrench and be careful not to touch the hot bits). The retraction trick in the end gcode to make Revo fully cold-swappable is just as doable on a standard setup, and you only need the heater block to be hot when you're screwing the new nozzle in, so you can be unscrewing the old nozzle, putting it away, and getting out the new one while stuff heats up...

[@ErtsenPlayGames]

0:35 that intro music ..... i instantly think about noctua fan comparison xD

[@ProtonOne11]

I get that pressfitting that core in there makes sense to get the best thermal transfer and makes it completely tight and rock solid. And it's probably easier and cheaper to manufacture than a threaded version. If you could unscrew that center core piece however, it would make cleaning/repairing or even replacing a worn out nozzle tip so much easier and cheaper.

[@MisterkeTube]

I had the same thought: how the hell would you unclog that thing? You will not be able to push a needle through it, right? Also cold-pulling won't work, I guess ... So, how do you unclog this if some cooked plastic gets stuck in that bottom cavity? Lemme guess, you have to buy another one of those expensive nozzles?

[@TheWoeggil]

Lining up the holes would be a nightmare with threads.

[@023douwebakker]

​@@MisterkeTube Probaly burning it out by heating the nozzle with a torch

[@yschroder]

And you could just replace the threaded insert to change the diameter! Wait we just designed a V6 hotend... My point is: by making it a threaded insert you would invalidate the whole design...

[@corlissmedia2.0]

You can learn many things about a person by watching their eyes while they speak. For instance, if, as a person is speaking, they close their eyes, this can be interpreted to mean they are inventing what they are saying instead of reciting something they know for a fact. When a person closes their eyes AND looks away (sometimes this is called "falling asleep"), we can interpret that as meaning they are unhappy or even ashamed of themselves because they know that have misspoke (another word for this is lie). I'm writing this here because of something I saw in your pitch for Skill Share. I don't doubt for a moment that many of the people are sincere and very creative / experienced. But then there are the hucksters. Being able to recognize that our eyes reveal our truth, I'll call it, is very helpful when you're putting together a team. Now, back to watching this GREAT VIDEO!

[@MirageDU]

I like that they kept the formfactor for easy switching. But on the other hand I would have liked a UHF version with an extended meltzone. Maybe that will come next year.

[@frankearl9285]

I suspect so. This is a nice system they've come up with. It's more robust in several ways to stock on most printers- and it's easy to change nozzles out.

[@derbacksteinbacker4942]

This is all cool and impressive… for people who already have Revos. I personally run my Vorons up to 200-250mm/s and specifically tune my profiles to max out the hotend as best as I can. As someone who looks for performance it’s hard to imagine me ever getting a revo high flow, I think the convenience of changing a nozzle in probably 10 sek less just isn’t worth getting yourself into this ecosystem wich is limiting in many ways. I have to walk over into another room to change my printers nozzle anyways, I don’t care if I change it in 20 or 30 seconds and with the auto z calibration adjusting the z offset is also a non issue

[@Yanceyray]

Great video and appreciate your work. Please put it on consideration to test 0.6 nozzles with ABS to see what the flow rates are. The heater capacity analysis was also informative. Based on your findings I suspect a 60w is required for 0.6.

[@frankearl9285]

I'd say it depends on the material. You'll probably do okay with PLA/PETG/ABS/ASA. PC and Nylon will likely need the 60W to gain maximal advantages of the nozzle design.

[@dsp4392]

Fantastic analysis. I think the value proposition might make sense for some very niche applications. I personally never change nozzle sizes, and a cheap knock off Volcano hotend with a CHT nozzle will outperform the Revo HT. At the price they're going for, I'd rather just buy a separate printer if I ever needed to print with a larger nozzle size.

[@frankearl9285]

That requires space...and if you're modding for specific things, you'd need to replicate that over multiple printers. Like the others, you felt the need to comment. Thankfully, you're more reasonable than the more mouthy in this discussion thread set.

Looks neat. Only problem might be that they are harder to unclog when needed.

If the insert could be removed separately you could open it so clean it and you would actually be able to remove the just the nozzle tip wear surface 🤔 E3D has pretty good engineering and they seem close to a really competitive solution

[@Unscientifically]

yea, on my ratrig with a server fan and with 40w revo, I cannot print temps higher than 255C. Otherwise the hotend just cools down and cannot maintain temps.

[@Javierm0n0]

Even though i am a budget 3d printer enthusiast if i were to get a highflow nozzle i'd probably end up getting one nozzle per plastic type if i was switching filaments and printing at a high volume. Currently i just push some filament through and clear out a diff type that way. I do love these HF designs though.

[@evafpv]

Curious what issues you've heard of with printing TPU with a CHT. I'm a FPV pilot so almost all of my printing these days is TPU for drone parts like GoPro mounts and using a 0.5mm CHT nozzle has allowed me to push speeds up to 50mm/s for printing some parts on my Voron V0 with standard 95A TPU. Cosmetic quality isn't "perfect" at this speed, there's some very minor surface defects, but I'll trade that for being able to print parts in just over 1/3 of the time any day. Always impressed with your vids! The level of care you put into each one is inspiring. I've been trying to devise a guide to TPU printing since I've been less than satisfied with what's out there on the subject but it's daunting.

[@specialingu]

i think i had trouble with some tpe 83 shore and a cht or cht clone nozzle.... id get very very thin walls, and then it would stop. i switched to a larger normal nozzle, and it behaved much better. im guessing its because the center of the filament is running head first into a obstruction.

[@zarster]

Could you consider to sandpaper away enough material on the tip to change the sealing point on the adapter and test it again?

[@ErtsenPlayGames]

6:55 YES , IT AFFECT THE FLOW OF CHT !!!! try it with just sanding 1mm of the adapter so it will seal it or cut 1-2mm thick spacer from ptfe that you will insert inside to seal it (use filament as a guide before you screw the nozzle in so the spacer wont move around when you squeeze it should work great ...you can even use slice engineering Boron Nitride paste to get some extra few mm3s of flow :) or better ...go with bondtech vulcano and 1-2 m6 nuts (maybe out of copper or bronze .... im curiouse how it will work )

I've tried the CHT clone some time ago, but I had problem where dust from filament got stuck inside the nozzle and I was unable to clean it. 1 of the 3 channels is clogged. So you should always use filament sponge filter or smiliar when using these kinds of nozzles.

[@antoniocross5956]

can you maybe show how to install it on the prusa mini?

[@TheAtomicSoul]

Looking at the cutaway, the new nozzle seems to have a "flat area" before it enters the thin section to be extruded. (As opposed to it smoothly narrowing to a point.) This looks like an issue with how it's manufactured, but could that effect it's flow?

[@smokeysify]

I wonder if its more efficient than a sharp tip

[@OscarOliu]

Looking at the entire nozzle, it looks like it might be stepping down the size to smooth melt path, if I were to guess anwyway, I am no engineer lol

[@andreask87]

Yeah that could become an issue over time and especially with obxidian variant + filled filaments... When you just look at the insert part standing on the outflow tip (like in the picture on the right side @ 1:45), the 4 bores that converge to the center have flat areas between them and the bore-edges are sharp and not chamferd or rounded, like with bondtech CHT. Theoretically those areas could act like flow dead zones and over time build-up of burned filament and other debris might occur until a natural flow-curve builts itself out. However, i guess E3D tested those long enough that this is not an issue with normal Filaments. Those flat areas coupled with the comparatively big widening of the filament path around the dome is most likely also the reason why Stefan could perform a proper cold pull. The plastic just gets spread to wide in diameter so you can't pull it through the typicall 2mm heatbrake/PTFE tube in a non-molten state.

[@CNCKitchen]

It will definitely affect flow yet if you read the E3D blogpost you'll see that they played around with various different designs and deemed this to be the best.

[@TheAtomicSoul]

Wait, @CNCKitchen: If the four diverted tunnels are 1mm each, then the path goes from 1.75mm to 4mm, to nozzle diameter. This not only explains why cold pulling didn't work (4mm down to 1.75mm), but doesn't that effect the flow rate when it starts and stops? Would it work better if each section was closer to 0.43mm to keep the area the same size?

[@TheEngineerC]

Are the specific heats of all polymers around the same as pla?

Adam used different hotends which makes "nozzles" hard to compare. Yet his results go hand in hand with my conclusion. Revo HF is good for it's size but if you want max flow, get another hotend.

[@realgoose]

@@CNCKitchen thanks for clarifying. You were attempting to make an apples to apples comparison. So if someone took the Revo HF nozzle design and put it on a traditional V6 style hotend… It would beat the CHT head to head? So Revo’s shortcoming is the length of the heat zone/break?

[@DarrenGerbrandt]

I like my Revo and will be upgrading my Ender 3 Max but the socks on the nozzles suck, both of the socks on my 0.4 and 0.6 only lasted about 2 weeks each before breaking off when I went to switch nozzles.

I've been having trouble with PETG prints on my MK3S+ with revo. I found that cutting the overall printer speed to 70% makes a huge difference. Maybe that means I need more cooling rather than the stock profile? So this is interesting, but I rarely print over 100% speed anyway. I might get the hardened revo......but honestly since I have an mk4 kit ordered I'll probably get a hardened nozzle for that once they become available. I'm really hoping for diamond back, but anway.....

[@t_c5266]

Does the bondtech cht fit in a standard ender 3 pro?

[@QuinnMorley]

The limiting factor with the power isn't steady state, it's when suddenly you hit a fat bridge area, double the print speed, and max the fan out at the same time. It isn't that you don't have enough power for that situation, it's a question of whether your PID will sort it out before the thermal protection kills your print. This was with a brass volcano block that was just suuuper sensitive to cooling. Really a struggle to PID tune for high-flow and fan on/off, even with a sock, so it's good to have some margin on the power if you are going with high flow rates.

[@Hooahboard]

Can this parallel switch deal with regenerative breaking. I know there are many of these on the market but they all have the same thing in common, they are used with scooters and ebikes that have manual breaks, and they can't support regenerative setup. Please let me know and thank you for your help!

I have not. Gotta ask Mello3D to send one over.

[@thorgraum1462]

where do you get that adapter?

[@trkoo]

What about retention? Doesnt the Complex geometry make it harder to pull back? Resulting in stringing with flexible and pet materials?

[@CNCKitchen]

Haven't seen more stringing on it, so far.

[@DigitalArtisan77]

From the cross section it looks like they mill from nozzle end before freezeplugging or pressing a piece in then milling that part to finish.

do I need to get an E3D V6 Adaptor for Prusa MK4/XL to use these rev HF on a prusa mk4?

[@Made_by_Henne]

Kannst du mal testen wie groß der Effekt von High-Flow-Düsen auf die Bauteilstabilität bei verschiedenen Extrusionsraten ist?

[@DiThi]

For that price it's cheaper to just have multiple hotends to hot swap with the voron's afterburner (which I use on a prusa i3).

[@lam_xyz]

Have you done the same tests with the rapido hf or uhf? I‘m interested in the concrete results. Btw afaik „rapido“ is Spanish and has the accent (Betonung) on the first syllable.

[@Joyntie]

maybe this will work for me, for some reasone i never got the CHT to work, it always clocked up....

[@AMidgetWalrus]

I really hope we get a standard Obxidian CHT nozzle. I'd gladly drop $50-60 on one of those. Not too into Revo, the costs well outweigh the benefits IMO. Also I see this thing jamming like mad with any kind of filled filament, though it's brass so CF is likely off the table already.

[@gabriell4031]

Wouldn’t it be better for E3d to make a 60w slightly extended heater? How much more would it be to make the heater 2-3mm taller? What kind of effect would that have on cost vs flow?

[@crosswindjones]

That looks like a modified stealthburner front cover -at least. Would you be able to share that mod?

[@pahvalrehljkov]

how do they heat dome in middle? first outer part, then filament then dome gets heated. so it doesnt heat from inside until it receives enough heat from filament tube part.

[@vipervidsgamingplus5723]

That dome piece is connected physically to the nozzle at the very end of the extruder. So when it heats up, the whole thing heats up all at once.

[@jothain]

What good it's to split flow as it can't be heated from center anyway?

[@michaelgleason4791]

If I ever get around to spinning up my 3d printing business again, things like this are worth it. For a hobbyist that may print a couple smaller things per day, probably not

[@dsp4392]

I'm thinking the opposite. In a business setting you don't want to fiddle with your printers. If you need to print in multiple nozzle sizes, you just have one printer for each size. In my opinion the Revo is mostly useful for hobbyists with limited space, or who really don't want to own more than one printer.

[@shy-Denise]

I want this nozzle in my Bambu X1c 🙈

[@MrPeloseco]

I have not tried the revo HF yet, and I want to, for sure. I have standard 0.4, 0.6 and 0.8 nozzles. It is true, I never changed nozzles as often as I do now, but I'd say that at least 80% of my prints are done with the 0.6 nozzle and with the speeds of the voron 2.4 I am limited by that flow. I really want to try the new HF nozzles but the fact that it is $45 a piece plus another $45 for the heating element... It really feels like a rip off. It makes me want to change to a rapido HF right now and go back to my ratchet wrench to change nozzles.

[@CNCKitchen]

I wouldn't call it a rip-off because these things are expensive to manufacture. Yet the design is definitely not made for super cheap maufacturing. Bondtech did a great job in that regard honestly.

[@MrPeloseco]

@@CNCKitchen maybe not if it's your first e3d hotend, but if you already have an standard one, and now you have to buy a $45 nozzle and a $45 heat element, that's adding $90 to an existing hotend. What am I going to do with my old nozzles and hot end? buy another heat sink and install it on another machine? I understand that are not cheap to manufacture but it doesn't excuse the fact that you are paying $90 for a nozzle.

[@3D_Printing]

We need more than just a nozzle

[@bleach_drink_me]

At that price I will keep waiting on the revo. That adapter to use a normal nozzle on a revo would be welcomed.

I guess and hope but looking at E3Ds track record I wouldn't count on it getting released this year 😅

🤔 I wonder what that nozzle would do to Tri-colour filaments? I think it would mix it all into one colour. I'd love to see what it does do to speciality filaments like that.

[@kurtnelle]

@CNC Kitchen, is anyone out there preheating the filament before it goes through the nozzle? I can't find a single project that's doing that. Perhaps you know of one?

[@schm4704]

Ever since the major suckage with the non-standard nozzles of the CR-10 S Pro (M6 **fine** thread, argh!), a proprietary nozzle system is a no-go for me, not so much due to price (although 40-something bucks is pretty steep), but mainly due to availability of spares.
