I think is is much more fun to get it as a file and print at home. As I am now printing with 100% PET plastic from bottles and I am always looking for some cool stuff to print, as my filament comes for free from the recyclable bin of my building.
Yes for part 2. I think it would be better if you added 2 more pieces to close the loop. It looks like there is a lot of air that would follow the path of least resistance and rise upward instead being fully entrained.
@slant3d Also, it would be interesting to make a third version with taller, open vertical blades(with the same area as the closed version) and compare the three versions to see if there is indeed any difference in airflow. Great video.
Now this is a really cool one. Takes a product that was innovative but limited by its manufacturing process and breaks it down to something much more versatile, flexible, and more suited to mass production
Super cool and great hair for this one lol! Did you apply that sandblast texture in cad or after in the slicer? Fairly new to this channel so was also wondering if you did tutorials on aspects like that?
cool vid! to your point of making the air flow more efficient, you can use Fusion 360 Simulation to test your design iterations. Can't wait to see Part 2.
Can this design be suitably adapted for a gaming PC? Cooling and airflow are always concerns, and a ducted version for ATX sized systems would be killer...
How well does this kind of design scale? I wonder if you could use this kind of "bladeless" design in, for example, a part cooling fan on your 3d printer. Or maybe as an air intake in a pc case.
Time to make a giant dyson fan for my garage. I wonder how far you could push the proportions of this. Besides all of that, Would you possibly Be interested in a collaboration? I have a 3d printed arcade idea thats badass.
is it more efficient though? i cannot wrap my head around that making more obstructions for the airflow somehow would make it more efficient at blowing air. otherwise why wouldn't helicopters or aircraft employ this design..
Around 35 % less efficient than classic fans. On flying staff, like helicopters and/or aircraft, it would be much much less efficient, on top of all the difficulties of directing the air flow. To see a proof of the last it is enough to observe how this "bladeless" (with blades hidden in the base) fan would behave when some wind is present - be it perpendicular or be it frontal (against).
i see one disadvantage: 3d prints are rough and for most cases it's fine but not for aerodynamics. Efficiency of 3dprinted part is much lower than injection molded part. Of course without any post processing.
The layer lines are perfectly aligned so that they do not cause aerodynamic issues. And even if they did they could actually improve performance liek the dimples on the golf ball
@@slant3d nice hypothesis although drag is proportional to surface area, so all groves between layers increase it drastically. A lot of youtubers proved that printed wings acts worse without sanding or putty/epoxy. Also golf balls have dimples but have smooth surface finish. FDM ASA prints have 22,5 um surfase roughness (as printed), injection moulded around 0,5 um.
You have to design the airfoils so that the boundary layer does not seperate from "wing" and that boundary layer than entrains other air to flow through them. It is the only way to make this type of bladeless fan
@@slant3d Things google thinks I'm interested in... For the last couple of day's I had reposting over reposting from "ai" news bots. Generative stuff without much of human interaction fully automated and horrible to read. Dyson and $25 is enough for the bots to spin click bait out of it.
I want to also see how you'd improve it and make it reaaallly benefit from 3d printing. Could the air foil be made more like a 3d sphere instead? It looks like their design really benefits from extrusion or bending to create the air foil
@@slant3d Those pumps are hot garbage. Yes, they move a lot of air but are prone to overheating and feature probably the worst brushless motors cents can buy.
Yes, develop it, unless there's a patent: 1) make it a rabbit sculpture, or robot, or bug, or anything with antenna/ears that stick up... which are the vanes. Also, in any design, it would be better if the vanes didn't start going straight up right at the base but had some intermediary shape. Or, make it a city- scape that happens to have 2 vane-shaped towers. Lots of fun sculpting options that would entirely hide that it was a fan. 2) add LED lighting that shines through various parts. Make it a desk lamp/fan. Go really fancy and make it one of those back-light 3D printed pictures... can't remember the name. Let people upload the picture they want. Automate the production of *personalized* lamp/fans. 3) make it a solder station with fume extractor. Much wider table in front, much lower profile. 4) in general, a desktop/shelf model with a much, much thinner base would be good. 5) add a water mister for cooling. Tank on the top, gravity drip feed into the vanes. Yes, leverage all that 3D printing advantage for tiny channels that distribute the water inside the vanes. Maybe funnel any excess water out to the top of the base where it can pool and evaporate or get wiped off. *But, a question:* Does it need a high-velocity fan to work? Or, put the opposite way, can a PC case fan move enough air to do anything useful? Mostly, thinking about noise. And, that brings up another video topic for you. Can you add 3D printed internal structures that dampen noise? Like, rather than having to add foam or something for noise dampening, can you just print a structure that absorbs the sound energy?
@@slant3d Really, a personalized kid-finger-friendly desk lamp/fan/mister might sell well... for anyone that happened to have a big 3D print farm. Print in white and advertise it as something the kid can paint. Oh, and I bet with some experimenting it would be possible to have the right sized or shaped water channels that only flowed when the air was being forced by the nozzle. This actually sounds interesting... might try it myself.
. @4Fixerdave Low humidity areas like Arizona would probably really get a lot of benefit from the built-in mister. But other areas like the midwest states, not so much. Might be good to have a humidity sensor built in. But then you would need a microcontroller and etc., etc. But it's fun to think about all the possabilitys
That's really cool. I'm not skilled enough to try and make something like this myself right now, but I'm interested enough to write it down for when I do have the ability to make a prototype!
(like 9 or 10 months later) You guys seriously released a video without showing how well it did? Feels like baiting. Are you the master of baiting? Are you a - (brought to you by Mr. Sockie)
This is a great idea! It is also interesting to measure the volume of air that is pumped by this "dyson" fan with an anemometer and compare it with the volume of air that only one fan produces, without aerodynamic wings.
Dyson fans are less efficient than regular propeller fans which are the most efficient and the least loud. Turns out that restricting air flow that you generate with fans hurts efficiency.
I would pay money for STLs for this fan. And if Dyson finally notices and tries to harsh the buzz, the files can be tragically "leaked" by a "hacker" to torrent sites and etc
Brilliant product prototype and video. Definitely do a Part 2. I could see including a multicolor LED (or 2) on the base between the blade wings to add a custom ambiance. A piece of plexiglas, or a semi translucent topper over the wings would increase efficiency and help complete the looks of the design. This topper, could also be a customization feature. It doesn't have to be an arc, it could be a cylinder, a small display shelf, or with extensions, a lamp shade.
Would be great to build a small version of this with a Noctua fan in the base. I imagine that would need some holes for air intake and adjustments for the internal air channelling but could be a great use of some spare computer fans.
Yes. In a nutshell, the fan in the base has smaller blades that have to spin faster. However, if you went with a UFO design, then the story might change. You still need to deal with an enclosure that restricts airflow though.
1:40. yes. yes i DO have an old fan with metal blades from 1950, and its run almost 24/7 for the last three years after pulling it from the cupboard, after the dyson fan TRIED KILLING ME IN MY SLEEP! i woke to that acrid smell of burnt electronics and plastic... the heater had turned itself on full blast, and melted everything before blowing the breaker...
Do part 2, and invest in a 120V axial industrial fan rather than an air pump. You should get a much higher airflow using a 12 to 20 dollar fan which has the same size and shape as most computer fans (120mm) but with a thicker profile of 35mm to 50mm versus 15 to 20mm for the PC fan counterpart. Then, add a fuse/breaker and an off the shelf dimmer switch sold for lighting. This should give you speed control for cheap. For the hardware BOM, it should be in the $30 price (not including any bulk discounts or shipping in from over seas) range while providing much better flow than Dyson. To finish off the top, don't get too elaborate, but stick with a functional piece. Maybe it could be printed separate and snapped into place. I do may facets of R&D for a living, so let me know if you want help with the design. I can run a basic computational fluid dynamics simulation to help you get a more refined design in a very short time.
Just wondering ... Doesn't Dyson have any of this patented? That could be a serious hampering factor for mass production, unless you're in China of course ...
I actually printed about 400mm diameter cicle with Dyson's wing profile, it has 110mm inlet. But I wasnt able to find motor powerfull enough to produce high pressure airflow inside that ring so it was very low efficient. Tried examble large stove / hoova motor.
I think most epic thing in these dyson fans aint just that "venturi nozzle" style outlet.. but that extremely good power / noise -ratio motor which makes tiny turbine produce high flow with good pressure
