Water-Resistant Vents for Industrial Applications | Design for Mass Production 3D Printing

[@Segphalt]

Meanwhile the real solution that already exists in industry, slats with forward and reverse c shapes where the C's interleave. (Also doable in 3d printing) And much more reliable at keeping water from getting in. You could do it with v's as well for easier printing but air flows easier around curves.

[@slant3d]

Very true

[@Raymond-Wu]

The best benefit of posting content online! Do it wrong and someone will correct you. Imagine how many iterations this would have taken if someone didn't know of this solution already 😂

[@Segphalt]

@@Raymond-Wu It's an option. I know I have burned many hours in CAD or thinking of how to save a problem to only later find out someone already solved it. That's why it's become my step one when I ask a question is "go see if someone else has already solved this." Will save you a ton of time.

[@swdw973]

the c's were the first thought I had when seeing this

[@GeneralPurposeVehicl]

I was thinking stacked stamped plates, but that works too.

[@panzervpl9406]

meanwhile the simplest way of preventing rain from getting in is literally just putting the vent on the bottom with some skirts on the sides, let gravity do most of the work

[@Sky_lars]

@@panzervpl9406 You do end up with the components being hotter in that case unfortunately. The hot air will get trapped under the skirt and you'll end up recirculating the hot air. That's why having the intake and exhaust in different locations is so important.

[@karllautman]

Sure looks to me like water's getting into the box.

[@timderks5960]

Yeah there is... With these slats there's a 45 degree path downwards that's just open. You could hold the print at a certain angle and just look through it. That's never good for stopping water. I get that it's about the concept, but this isn't a great example.

[@shivaargula4735]

@@karllautman yeah, it doesn't really match how things are done industrially. Rather than a bunch of slats, these types of louvres usually have "S" shaped paths letting the air flow upwards into a room or chamber, but the water won't have enough momentum to do that. Couple this with slats which will stop any horizontal momentum from a jet of water, and you have an effective barrier.

[@kubenoz]

[@ardemus]

4:00 and 8:32 -> I love you guys, but--and correct me if I'm wrong--even though the water gun isn't delivering much pressure, a lot of water is getting inside during both of the water-resistant vent demos (particularly at 8:32). There is water *under* the container in both demos, but I swear that there are drops of water inside, up to and around the candle at 4:02, a stream of water running along the inside corner at 8:34, and a lot of water inside at 8:41. It's much better than a louvered vent, but that candle will only stay lit with luck and good drainage.

[@Pystro]

Yeah, only good for a candle that's elevated above the ground. I wouldn't want to put my tissues in there.

[@maxleung314]

At the 4:00 mark, you can see there is a gap between the model and the cardboard. Water probably go in there that way. Also notice that there is water outside that is under the enclosure, so it might look like there is more water inside than there really is. But I do see water droplets inside - probably because of that cardboard gap. The 8:32 one, I don't see any water droplets inside. Hard to tell.

[@dl5244]

there was also only the one port to the "box" (looks like a square glass vase on it's side). This means that the internal pressure alone will push against ingress. i suspect the water ingress would be much worse if there was a fan intake and/or a vent outlet

[@abdulrehmansiddiqui6666]

I really appreciate this video, I used the principles in it to design a air vent for my laser cutter. I wanted air to be able to be drawn into the enclosure without allowing UV to escape. The resulting vent is performing beautifully, with minimal impact to the airflow. Really couldn't come up with a better solution in my case. Thanks again

[@mcb187]

This is basically how light-tight vents work in darkrooms. There are similar designs for “daylight developing tanks” that allow water in, but keep light out,

[@wubbsy]

If you don’t need access to outside air just seal it and expose a heat sink through the case. This also prevents moisture getting in and makes it basically waterproof.

[@t3ddi]

After opening for maintenance the air inside contains moisture and can still condensate. So unless you purge the air with a gas or add a solid state dehumidifier, the initial problem isn't solved.

[@prophetzarquon]

Fill it with mineral oil

[@jsincoherency]

I don't know what I'm talking about, but your Tesla valve model looks wrong to me. It's meant to be basically a straight line in one direction, but lots of loops in the other direction, whereas yours looks symmetrical?

[@Max-bd9xg]

No, it doesn't have to be a straight line. It's just about the corridor that turns 180° and leads back.

[@t3ddi]

If you mean the teardrop shape vs the circle; The teardrop seems to be better optimised for creating the reverse flow with less turbulence, whereas the circle can be printed smoother. Due to the angling of thew channels, gravity will also help against the water entering.

[@swdw973]

BTW, because of youz guyz making me think more of commercial and industrial applications, I'm using my printers more for work than I would have thought. Which is giving me the experience I need with different materials, design, and prototyping before starting a 3D printing side business. Can't thank you enough for your channel.

[@Silverstar1995]

I was musing over how to remake the window mount for my portable AC's 200mm fittings, and trying to figure out a good way to keep the air flowing, without letting water in when we get high-wind rains. You literally just solved that problem for me here. Thanks, guys.

[@electricalychalanged4911]

Using TPU would eleminate the layer adhesion issue it might also provide a selfsealing contact point were your intersects with the box

[@Mama_esta_presa]

Neat design but woldn't you be able to produce this in layers if you had different spacings at the top and bottom? That way you could stamp 5 copies of the same part and just rotate them so the slits are covered each time.

[@smashedsaturn]

Yeah this is probably the worst application for printing. You could build this out of asymmetrical stamped slats and spacers for two part numbers and way faster and cheaper.

[@yearofthegarden]

This is a great design process. This design would work perfectly for a small solar panel box that gets left outside always. I got into 3d printing because I needed an endless supply of vent flanges which were $15 a pop for ABS injection mold versions. I grow mushrooms and hydroponic vegetables, and 3d printing everytrhing I need has changed my life and while it is very time intensive to learn 3d printing modeling and maintenance compared to buying all the parts, it really is enabling me to have more specific tools and solutions at my disposal

[@my3DPrintLab]

Just a thought, but if you made the front flat, you could put a logo on it. Then, with the drain at the bottom, put a larger interior hole for air flow. And a couple of vertical slats inside for support. Maybe? See! You got me thinking! Great video!

[@enjoying28]

close but lookup hurricane vents they have size rating for setting air flow rate and catch mist and rain

[@aprogress2374]

Water: yeah, you got me. i can't pass through, but he can! Humidity: hell yeah!

[@michaelmueller9635]

The question is, how much it does reduce or limit the airflow. I mean, designing for production is ok, but priority should be the requirements of the product and usecase.

[@inoid724]

Very nice, exactly what I need for the two class D amplifiers on my rickshaw - ventilated but splash-proof, brilliant.

[@darknessblades]

The best way to print these valves is not in the flat orientation, but at a slight angle. so the overhang it has is enough to support it. YES you will get more waste material, though it should resolve long overhang issues.

[@AerialWaviator]

If you look along the sides of a shipping container, near the top, you'll see a design similar to this to provide ventilation to the container without letting in rain. Very similar other than they tend to have vertical orientated slats. Think this might be to aid water to channel down a slat that has encountered a slat, vs. dripping from horizontal slats.

[@WoodmanFFM]

That was exactly my thought when I saw this design: Why not mount it with the slats vertically, this way the water would drain faster?

[@UNgineering]

so simple yet so effective

[@tasa4904]

This is something I've been trying to design for months now for a window fan. Couldn't come up with something that looked natural but still let air out and didn't let water in...

[@bellwetherhacienda-fs6yy]

cool discussion. I was interested in vents as I'm building a marijuana drying box and haven't yet put a vent on the fan. I was thinking something that opens and closes, but slats would probably do a good job of keeping humidity in.

[@lemon9.9]

It’s literally as simple as I thou it would be

[@R7000-w3x]

excellent work, great ideas!!!

[@Roobotics]

4:55 Nah, would be easy to scale with other methodologies. You make the parts in rows with an offset of 25% the pitch from one another's blade distances, then when you stack them rotated 180 every other tile, they will have a 50% overlap on each other, all the other spacing is kinda arbitrary fluff for your STL.

[@davydatwood3158]

I'm not the target audience, of course, but this does give me some ideas about how I might pretty-up my very jury-rigged ventilation fan in the window of the spare room my printer lives in.

[@agustinlopez4943]

Correct me if I'm wrong, but isn't the orientation on the XY of the hexagonal prototype irrelevant? I mean yes the first layer is going to be stronger, but the next one is going to have the opposite orientation neabubg shorter lines. What's the difference between a stronger 1 layer but a weaker 2 layer and the reverse?

[@rodrigolucena1698]

This is amazing! I wonder if it is possible to 3D print something sound proof like, where it blocks the sound and leaves the air pass?

[@homo192]

I did such a thing and it works great. Turned out quite bulky though, because I wanted the air to travel as unrestricted as possible. The inner areas of the device have been covered with felt to absorb all the noise.

[@SilverStarHeggisist]

Well there's companies making 3D printed suppressors for firearms.

[@LightOfReason7]

Extremely cool

[@ifell3]

Good stuff, you could also do something with light blocking vents. If for some reason you needed to vent something without all the light shining out. Not to sure what 😅

[@yeetsbeets9894]

One problem I could see with the design, is that if air was somehow flowing in while there was water or moisture in the vent, the airflow might carry water droplets with it and maybe cause problems.

[@reddevil00745able]

In summary: 3d printing good👍

[@Tony-pm5xo]

I made an improved splash proof vent after watching this. It's for electric housing for another project. One comment mentioned interlocking C so it's kinda like that. Tho I don't think my shape can be made without 3dprinting. It works great. Not quite waterproof, but prevents splash. Can't post link for some reason. Anyone interested, it's called "Splash proof/water-resistant vent" on printable

[@Jimmy___]

PLEASE can you do a video on vents that don't whistle in the wind? Waterproof or otherwise!

[@dougcox835]

I think that if the slats were angled they would direct the water away from the output side and have drains on the top or the bottom I haven't thought this through but it might be possible to make it such that water will drain to the outside whichever way you orient it. Maybe circular angled from the center so water will drip towards the outside edges everywhere. Water coming in the top half would go right through the slats but the second layer would catch that and just drip down. Another thing that comes to mind would be using centrifugal force to separate air and water. Basically some sort of internal fan. Not powered of course but rotated with the air flow and flings water out where it could drain away. This sort of think would only work in a setup with forced ventilation, not passive cooling unless it's very windy out.

[@spoon1272]

I think you should have rethought the example at 0:15. Come on... only a muppet would put that isolator anywhere near water and it doesn't need to be cleaned. As many others have pointed out, you can see water going into your example at 8:34.

[@swdw973]

Interesting, but I know an alternative to straight slats. And it looked like there was a filler in the black one too. Which, unfortunately can act as a water trap and turn it in to a humidifier if the fan is blowing into the enclosure. Thanks for the idea though. I have several sites I work at where I can take the idea I have , design it, print it and use it. Doesn't have to withstand washing though, just rain and snow.

[@SteveM45]

[@WillPower311]

[@mdandry]

You can just make the front slats with a drain at the bottom, followed by an angled wall with a opening at the top of the wall, then backside/interior slats... sort of like a transmission line speaker box. What I’m imagining should be completely water proof and a bit simplified. I can make it in fusion and send it to you if you’d like .

I'm so confused. Don't louvered vents do this? Alternatively, you can have an intake tube that points any way other than where the water is coming from (but preferably downward) to have air intake without taking in water. Is there some design constraint I'm missing? I love 3D printing, but isn't this an age-old problem with age-old solutions?

[@SilverStarHeggisist]

louvered vents are one way air flow. This might be for an application where you want the air to flow either direction. A possible example might be a enclosed computer control box that you want to have the inside air exchanging with the outside air.

Should not every chamber have drainage and not just the first one. Would it not fill up with water and dust with time otherwise. And even it he basic idea is just as I would do it on my firs attempt too. I do not think the vent is optimal for either stopping water or letting a lot of air pass through. Maybe it would be enuff to have all the ventilation from the bottom then having the ventilation canals go out in an angle from the bottom to the top. Then the canal would go in an angle down to the thing you want to cool down. So the ventilation canal should be in an angle like this: < < |(wall)
