Is E3D Revo Finally Ready for High Speed 3D Printing? Revo HF Review

E3D Rapidchange Revo sees its first high speed nozzle today with Revo HF, a high flow variant that uses new performance increasing internal nozzle geometry to increase surface area but how much faster is it?

I've written a short article to answer some of the questions you might have after watching this video. I've written it on my website so I can support it with images etc. Hope it helps.

Can't remember the last time I was this excited to watch a video about a nozzle. 🤣

Great video!

[MandicReally]

Excellent video. Waiting on my kit to arrive (and a printer build being finished to run it on) but I'm excited. Also adore your "Results will vary" addendum. So tired of "But so-so got different results, yours must be wrong!" comments.

Got my Revo HF upgrade kit in two days surprisingly direct from E3D to California. So far it is definitely an upgrade. I easily printed a Benchy (decent quality) in 20 mins with 0.6mm HF nozzle with PLA with no tuning. I'm sure I would be able to get around 15 mins with PETG or ASA/ABS. I'm pretty happy with it so far but more testing is needed. I think for its size, it is really good from the looks of it

When modifying my profiles for CHT nozzles I noticed that they require a bit higher pressure advance than plain nozzles. And on small complicated prints that can actually result in slower printing if a large enough percentage of the time is spent decelerating into a corner or acceleratin from one. So now I keep my CHTs in my V-Core 3 500 and my V-Minion can actually print some small things faster using non-HF Revo hotend - higher accelerations and lower pressure advance each contribute to that. So I think for some printers and/or users the new HF Revo could be a total vaste of money because if you can rarelly reach the limit on flow-rate the extra money will not increase the performance at all.

Absolutely love your attention to detail and targets used for testing. Thank you for taking the time!

I have one of these in my first Voron (switchwire) and was waiting on something like this. After seeing the pricing I was a bit disappointed and admittedly even more so with the performances but that being said I need to temper my expectations and really consider that the technology is crammed into a small light package and like he said in the video, the size of the heartbreak isn't as long as something like a volcano. I'm still going to get the .6 if they don't sell out because that one looks to offer the best bang for buck.

When I got the email "REVO HIGH FLOW" my heart sunk. I just bought a revo voron single nozzle kit. I thought it would be a whole new hotend. No... it's just a nozzle. I love this! Sadly I've spent so much money upgrading my ratrig (dual filament, FFFM, wobbleX and just purchased lots more for AWD). So I don't want to spend another £30 on just 1 nozzle for my v0 which I'm currently building into a F-Zero.

Reasons for Normal Revo vs. HF: Usage with Prusa MMU. I need clean Tips, which I don't think are possible with the HF Variant or CHT. Also of course, printing with abrasive materials, as no ObXidian version seems to be available for HF.

[philspencelayh]

I was puzzled, to me Revo is a digital audio company and I was intrigued to see how that bit of metal was going to upgrade my audio. Small world.

[therunophil]

very interesting, I love my Revo for the convenience on my old Prusa but I would have hopped the HF version is a bit more competitive, Revo volcano using the same nozzles would be great. But seeing how long we had to wait for "coming soon" HF I guess we'll have to wait quite a bit, if that is even planned.

[BallisticTech]

Very cool video. I like your data driven approach and acknowledging that it's very difficult to perfectly match other flow rate calculations or findings.

I think while Revo + HF Nozzles isn't the best performing combo for Volumetric flow, the versatility the platform offers somewhat makes up for it.

I've seen these on tiny Prusa Mini's printing tiny Mini-figs with a .15mm nozzle. Seen them on MK3S's printing CF/Nylon and other abrassives with ObXidian. And seen them on Voron's pumping out parts and printing at 200-300mm/s (obviously layer height/width can make print speed look very high)

But any of those printers can one handed cold swap out that specific use case nozzle and put in another for whatever reason. That's pretty cool.

So maybe not a master of any specific use case, but a great Jack of all Trades? $80-$100 purpose designed HF Rapido? Or $80-100 Rapid Nozzle Change Revo that can now get better VFR.

i really loved the revo concept when it was announced. i've preordered the revo six full kit and the voron revo. But the lack of high flow and hardened nozzles led me to use a Trianglelabs 115W CHC Pro which is cheaper and much better at higher flows. why would i get my revos out again if the ObXidian Nozzles and the 60W Heaters aren't even in stock.

[TotallyGlitch]

I will take ease of use and compatibility any day. They are solid and consistently work with less fuss. So i will be sticking with my Revo.

[technicallyreal]

Some reviews have shown the CHT negatively affects retraction or messes up compatibility with TPU. Does Revo HF have these downsides as well?

[biozombieactive]

YES!! Highflow is here!! I need them!!

[TheZolon]

I was already on the fence on switching out the cht nozzles I currently run... now I am even more on the fence. :p .. I think I need to convert a printer to the revo system at least, so I can get some hands on experience with it. Thank you. :)

[calaphos]

I'm a bit hesitant spending 40Eur on a nozzle that is a wear part after all, on the other hand I've yet to replace a nozzle because it was worn out so that might not be a rational concern.

[MrHeHim]

Now, if that insert was made of tungsten 😍

Although it seems like getting the old filament out might be a pain and require more than normal purging

[colinfagan]

Would be interested in seeing if the 60w heater core gives a significant improvement.
