that happy laughing at 2:40 xD
I laughed almost simultaneously...lol
@@tigre3droyce771 same thing xD
@@SergeiSugaroverdoseShuykov I am using the 4020 radial fan myself..they blow slighty weaker... so I thought I should get the 5015 to achieve the same wet mess Lol..
2:33 LOL bro at this point is not a cooling solution but air conditioning 🤣🤣
You should call this duct, "El Toro" (because it looks like bull horns)
I was think Maleficent, but then Disney would sue.
El Tornado ;)
It reminds me most of stag beetle horns.
To me, it looks slightly satanic... ;)
Just an idea you might consider to take this next-level: I've gotten excellent mileage out of running 19mm CPAP hoses to my effector to provide cooling air from larger compressors. They're very durable, and they free you to use any size/power fan you want. Remote fans also reduce effector weight into the bargain. Think of having a shopvac's output blowing through that nozzle, for instance 🙂
I have designed something already with 2x120mm blower. And it was blowing a lot of air.. but the big tubing was making me lose some Y space. But CPAP option .. i will definitely have a second look
I like the laughter. Noisch one!
Looking good mate! I've done a similar design where I've put the radial fan at the back too, but I've switched from printing the nozzles to just using copper or brass tubing instead... So now my printer head is slimmer in design from the back to the front. No more wide printer heads or the use of dual radial fans. Makes sense... ;)
These fans are no joke. I just flow tested against Winsinn 12v fans I also overclock at 17v. These do handle 24v very well! 5.0 CFM @12v and 7.7 CFM @24v. Still does 6.5 CFM @24v through a Hydra Narrow cooling duct (2.5mm x 9.7mm opening). Thanks for the good find!
This is the best fan duct style. I had similar one in one of my printers it’s really great.
Lol here I was about to turf my 5015s in favor of a berd air style set up and now I'm not sure...
Awesome content as always!
Love the design! Looks like devil horns.
Sounded like it was about to blast off into space!
Looking great, what a blower 👍😀
Holy crap that was awesome!
What about priinting a velocity stack for the case of the fan?
wow, that is powerful fan
Overvolting a fan is dangerous, but I can't argue with the results.
Might be a dumb question but what’s this boosted fan could you give more details ?
Looking at the world of very fast 3d printers I feel the urge to start tinkering with sub-ambient print cooling. Imagine high cooling potential with precise delivery and low enough airflow to not warp earlier layers. But first I need to build a goddamn fast printer :D
Have you weighed the entire tool head? Just curious looks like alot going on was wondering how heavy it is ?...
I like the velcro zipties also they are so handy
I have not since I've changed to Magnum+ .. im too affraid of the result now lol
Where we can get the 3d printed parts for the printhead ?
Nice, clean and functional.
I always wondered why people don't use external fans and some kind of hose/tube arrangement. I've seen compressed air setups but why don't just put the fan outside where air is colder?
Hose will probably introduce some vibrations that would be not very consistent and easy to tune out...
Nice subie
what hotend is that?
I feel like ive seen it before but i forget where.
Also i remember back like 6 years ago looking at building an OG Voron, ended up buying a maker select instead, kinda wish i had built a voron instead lol
Magnum+
Damn, where did you get your fan from
Awesome airflow! Quick question how do you get a 12V fan to run at 24v when I plug in my 12v fan to a wire at 24v it doesn't move at all. Am I doing something wrong?
Not all brand and type will allow over volting
İt would be good to know overvolting voltage and a product that you bought(link). İ mean was it cheap 5015 or included expensive bearings on fan ?
Very good questions. I added the info in the description. Thanks
Super cool to watch you innovate to print faster, especially since I'm doing the same thing. Except I'm using an ender 3 thats basically custom at this point with a bed that weighs near 15lbs.
15 lbs!!! How slow do you have to run it?
@@otroe i can do like 50mm/s on infill but even with my 20mm/s outer wall speeds at 100 accel I still get ringing. Hoping input shaper can solve that issue so I can print quickly again.
@@owowowdhxbxgakwlcybwxsimcwx I've tried 100, 500 and thats about it after I installed an ender extender kit with the silicone AC bed heater.
Ohhhhhh a ENDER extender if so I have one toooo
@@computertecky4744 yeah I bought the 400 kit and did the xl portion myself and saved about $30. Kinda crippled my machine for a little while in terms of speed but with klipper things have changed a little bit and I think it might be possible to push 150mm/s again.
damn that's a lot of air what kind of blower are you using. i can barely feel mine with my fingers lol... gotta fix taht but depression.
For visual testing of airflow it is good to use cheap "vape" devices (maybe a little modified).
Yes ill buy one
@@Vez3D I use a small $30 fog/smoke machine from Amazon and it works great for fan duct validation. Cheaper than most high flow vape pen options.
What voltage are you running for the fan? i use two 5015 and i dont think i have as much cooling as you from this single one :D
24v..and its a 12v
@@Vez3D 😳. 👍🏼👍🏼
On slice engineering's store page for the magnum+ it states not to use any plastic mounts for the dual cartridge setup, do you have any concerns going against their stated recommendation for mounting?
"Attachment by plastic structures is prohibited if dual 50W heaters are installed since plastic restricts the dissipation of heat, may soften and structurally fail, increasing the risk of injury, fire, and damage to the 3D printer."
Oh Hi Nero! An honor to see you here my friend :) im a fan of your channel. Honestly Im not sure why such a big warning about it. Its fine. I tested with 400c and the the max it got on the top mount was 38c... where it attaches with 2 m2.5 screws. I was only worried about my front carriage plate...but testing shown that it doesnt heat at all there with the cooling fan blowing. My laser thermometer gave me 42c at the most. And all parts are polycarbonate carbon except the front plate that holds the magnum heatsink. Its abs carbon. And the temp there doesnt go above 40c as well. The fan keeps it cool. So no.. i have no concern at all. I think they are being very careful and careful is always good. PLA would be bad of course.
@@Vez3D Cheers!
Im sure the warning is a big ol CYOA lawyer speak thing, happy to see you tested it though and really, there will only probably be an issue in the event of an uncontrolled runaway.
Personally i just find it kinda funny slice has this big wall of warnings you need to agree to before pre-purchasing one, and i've yet to see anyone who has a pre-release one for testing/content actually mount it using their own guidelines.
Keep up the videos, good stuff :)
perhaps try to make a de laval or aerospike nozzle for maximum pressure
You should call it the Moses duct! Because it parts water.
Can you release the files for this and your old fan duct because I’m planning on doing something similar
What operations did you use to create the duct? Always been curious how people pull that off. Also, nice 1.8 :)
@@Mekanikalistik yup loft! I didnt use rail in this one. And its a 1.5ishh ..custom a bit
What fan are you using for that effect?
5015
I’m building a vcore and I would like to have that whole extruder assembly
look up the EVA carriage platform.
His looks like a modified version
What stepper or servo drivers are you useing
For the extruder? 2209 at 24v. I also tried 5150 at 48v but it kinda overheated haha
For the motion system its ODrive bldc
@@Vez3D Awsome
where can i download the duct
How long did the 12v fan last at 24v's... I would imagine it burns up.
Going for months. And the one on the print head have been going for couple weeks. Only one brand is lasting that long. Link in description
Does this end up blowing the filament out of place?
So far so good
won't this cooling speed break the filament while bridging ?
You can tune cooling for bridge
I was like "wait this looks way worse compared to his normal prints" until I noticed you're printing on a different printer xD
That voron can print high quality too
@@Vez3D I know but yours is something else :p
5015 radial fan?
Cool fan duct. Also how did you overvolt the fan without exploding it
ball bearing fan. Its a HK fan. I have the same fan that has survived more than 3 months like that..and its still going on. Lets see how long this one will last :P
@@Vez3D Which model is that fan?
@@pikehh 5015
is that a Voron logo on a completely non-Voron printer?
thats a Voron logo on a Voron printer. Voron 1.5ish. Its a 1.5 modified a bit
@@Vez3D huh I thought you mentioned in one of your videos that it was a heavily modified Tronxy or something, must have mixed something up
this is a pic of it when I completed it couple years ago. It since has changed a bit... but not by much :)
photos.app.goo.gl/bLED78WGCrVLdCECA
@@nazariimoroz6216 my main printer (vzbot) is from a tronxy x5s...well..the frame only. That voron 1.5 has used an organ donor from a tronxy x3a
What brand is the 5015 fan?
Hk i think
How's the fan holding up now vez still going strong?
Yes after months beeing overvolted and shook at crazy accel/speed...it's still going on
Belle jub!!
QC?
Could you please share the stl file, for the fun duct. Don't have any soft to deal with the step files..
Sure. But it will only fit my setup. And it uses a EVA carriage
@@Vez3D That's perfect, I use tinkercad for adjusting the designs ...
@@Vez3D I have a mosquito liquid on a sender 5 plus enclosed and would love to try and modify for my machine. The two runners and the 5015 fan mounting I would keep. Thanks and we love your videos. Congrats on the 700mm/s prints… amazing.
@@soulvagabond i highly recommend you to learn fusion360 or onshape. You will never look back on tinkercad :)
DAMN!!!
Hi have you the Fanduct uploadet at thingiverse?
No..but it's on grabcad :)
@@Vez3D I found it thanks. Made a version for my HevORT with a Berdair connection. Now I wonder why you get so much more out with a 5015 fan (according to specification 9.8L / h) and so little with my Berdair (normal 15L / m)
@@svenbaum6227 He's running that poor little 5015 at 24 Volts, that's why xD
got a link to the blower?
www.amazon.ca/gp/product/B07PM1PF33/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
This looks like an EVA hotend mount
Because it is :) a bit modded though
yop, a perfect fan does not blow on the nozzle, but towards the plastic, too often we see fans blowing towards the nozzle, it is a big mistake.
is there no risk of fire overvolting i leave my printer on over night that's all
I did experiment on this a the way up to 36v and the wires are go very hot and start melting, and it just shorted themself but the mosfet got killed. I would say at 24v its still safe with that brand. Been running mine for a year and no issue.
Do you release these files?
It is released already. Just not with the magnum+ .. but i can provide it too. For the normal.v6 mount or nova mount.. check on yt page info. Link.is there. Or go to grabcad and look for vzbot
@@Vez3D cannot locate either. 🤨
5015 fan ?
I feel so g-thuggy when I hear the Vez intro
😄 some people might dislike that song. I like it :)
So much air that the filament's going to get blown off before it gets a chance to adhere?
Never enough cooling at high speed :p
Too bad theres not a simple way to try cold air. It might be more effective than just high volume, ambient air
There is a very simple way to try cold air. take a berd system. Run the hoses through a bowl/cooler of ice water.
I'm a big fan and caffeine works wonders for me, have you tried it ? XD!
haha
Dude. Put a towel under the glass. ;)
I don't understand why you don't use an air-pump ( berd-air for example ). Would be perfect for your speed-runs.
im also thinking about it. But this is way more simple. :P and it blows a lot of air at high velocity
@@Vez3D think about the weight you save ;)
@@Vez3D The problem is that the air that you are blowing is already warmed by the bed. Even multipling the flow by 100x will likelly not cool the print faster because in the plastic, its the temperature difference between core and surface that determines how fast the heat can come out. If you want to cool ABS (0.2 thick) from ~220°C to ~100°C using 80°C air, I estimate between 8 and 12 seconds ... assuming that the air flow is sufficient to keep the plastic temperature at the air temperature. Using an external air source allows you to control the air temperature. With ambiant air, the cooling time drops to about 3-6 seconds. Futhermore, if the initial pressure of the gas is high, its sudden expansion will cool down the gas even lower than ambiant. (PV=nRT ... if P drop for a fixed n then V increase and T drops) For example: assuming the gas starts at 27°C (80 F) and 6 bars gauge (~90 psi) it would cool down to -100°C (adiabatic assumption). Of course this jet of air mixes immediately with the local hot air, but some cooling effect can be expected. I really think that a compressor is the way to go ... you probably donc even need a tank ... just shove everything that comes in through a small nozzle ... of course a nozzle that is too small could cause over pressure issues so having a pressure switch to shut the pump and a relief valve would still be needed.
Air-pump: Less weight and no vibrations. And it can't suddenly fail on the printhead itself. Less/no tinkering on the printhead if the cooling fails. And no wearing down ball bearings of a fan that is being knocked around.
Cons: consumes way more power(?) and might be too loud....... expensive
I never tried boosting a 5015. I just came to the conclusion they couldn't keep up with 300+mm/s and moved up to a 5020, and not all of those are the same either. I'm rocking a ADDA AB05012UB200B00 now that produces similar results seen here without overvolting it.
attach air tube to fan from an air conditioner to blow cold air
in this application the volume of air is more important than the temperature of it.
Voron with Nova Pog
I think I am faster than your printer lol
haha indeed !!
Should have printed in ABS and smoothed the prints! for less drag.
Good idea!! Its ABs carbon. Not sure how smooth it can get

If only mosquito magnums weren’t so much $$$
