@@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.

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.
@@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.
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.
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.
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
@@ardemus its a nice proof of concept.... But i think if the sections in the front can be joined to the back layer with each having a slanted roof to a blind end that issue can be solved and will remain easily printable
idk I alway see this guy and he's so sure about what he is talking about like its rocket science, meanwhile there are better 14 yr olds at 3d print design on printables or thingverse
the way boats do it is that they have the air intake, then a collector box underneath it to catch the heavier water, then an intake for air at the rear top of the box to suck up the useful air
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,
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?
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.
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.
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...
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.
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.
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.
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.
Make use of positive pressure and a blower fan. With the output of the blower fan sealed to your guard cover and blowing outward, you'll have significant resistance to anything getting in. A moisture meter could be in the outlet of the blower fan to indicate when an issue exists.
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.
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!
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.
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.
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.
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.
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.
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
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 😅
Designed something sort of similar about 30 years ago to keep the machine operators from hosing down some quarter million dollar pieces of equipment and then complain it wasn't working properly. They wasted up the manufacturing equipment with fire hoses. Had a local metal fab shop build they. They were expensive.
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.

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 .
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.
Hello My name is Ahmed Hassan Al Mahdi. I really like all your videos I want to ask you about something When making molds from silicone rubber for some plastic products What are the best materials that can be used to make products
Buuuut, when you introduce a forced induction (fan), gravity might no longer be enough of a force to make the water drop down, and with suction could also create new avenues and routes for water to be sucked in before it is drained out.
lol, i literally inventing this thing right now! i have zero resistance filter on my bike, which is getting wet during rain, but now we have -1C degrees outside, and water it frozen inside carburetor, the needle is stuck 😑
calling this water-resistant is straight up clickbait. any exposed electronics would short out, especially if you have a fan there splattering the water all over the place
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?
The only provlem is planned obsolescence of said components is produced since you can't fixed something 3d printed. You will need knowledge on how to recycle of said component, or we will have an excess amount of broken components in landfill.
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?
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.
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.
your remark about reducing the distance / thickness of the slat does not work as capillary forces will take the fluid over to the next level, helped by the air flow. btw. thanks for your excellent videos on 3d printing!
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)
this is a solution to a problem that doesnt exist. Metal vents with the slots looking down might not stop rain coming from the bottom, but just put to vents and it will, and it will still be cheaper and more reliable than this. Unless you inject these for the "fancy" factor, then these are useless
Please please do something about the spit bubbles... they distract me (maybe others) from your subject. Swallow before recording? It's in so many of your vids and it's distracting AF.
This should be called an air filter. A vent only needs louvers to prevent rain water from entering the pipe. A vent is 50% decoration. A hole cover. :^)
@@tazanteflight8670 But it is not an air filter, that’s definitely the wrong word because the term “air filter” already exists and has an established meaning (a thing that filters out solid particles from air).
@@tookitogo Actually...... the definition is "a device for removing particles". A better definition would be it removes contamination. A vent is a hole.
@ If you understand that, then why would you make the original comment saying “this should be called an air filter” since it most definitely is not one _by your own definition?_
@@tookitogo Water can be a "minute portion of matter" aka particle. Water can also be called a 'contaminate'. What is your point? A vent doesnt change the medium. A filter changes the medium.
Why would you 3D print this when you could spot-weld some stamped sheet metal together? these kinds of vents aren't hard to assemble, and stamped sheet metal is one of the cheapest manufacturing methods in existence for high-volume parts.
Industrial solutions it's just a heat exchanger. Completely airtight/watertight. And has internal fans for circulation for the inside half of the exchanger. CNC machines in fab shops will be the most crusty disgusting thing you've ever seen. But the inside of their electrical cabinet is spotless because they have been using heat exchangers since the 60's on equipment.
@sha_hito under "normal" circumstances like room temperature it doesn't really matter which definition of air you use (oxygen or atmosphere) it's a gas
Definition from Wikipedia: In physics, a fluid is a liquid, gas, or other material that may continuously move and deform (flow) under an applied shear stress, or external force.

Just do gyroid infill with zero top and bottom layers
asymmetrical; so it can only be installed right side up
and light cant get in ...usefull for some things aswell
Would have been nice for a dark room
Also avoid insects, that's why it need closed
Why not just print a solid vent cover to place over the hole? 30 degree slope or whatever. There is water in the box 😅
"air is a liquid"
science has gone too far
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)
Now put a fan in there and suck everything through...
Wouldn't this still cost something like $20 per each to print? Doesn't seem to be cost effective
Unfortunately this method makes natural ventilation real hard, needs forced ventilation.
Or just stamp them and glue em/ screw them.
this is a solution to a problem that doesnt exist. Metal vents with the slots looking down might not stop rain coming from the bottom, but just put to vents and it will, and it will still be cheaper and more reliable than this. Unless you inject these for the "fancy" factor, then these are useless
Please please do something about the spit bubbles... they distract me (maybe others) from your subject. Swallow before recording? It's in so many of your vids and it's distracting AF.
The dude probably has a cleft palate? Don't be a dik
I just noticed this too. I can't stop staring at it
Just handle it u wimps XD
This should be called an air filter. A vent only needs louvers to prevent rain water from entering the pipe. A vent is 50% decoration. A hole cover. :^)
@@tazanteflight8670 But it is not an air filter, that’s definitely the wrong word because the term “air filter” already exists and has an established meaning (a thing that filters out solid particles from air).
@@tookitogo Actually...... the definition is "a device for removing particles". A better definition would be it removes contamination. A vent is a hole.
@ If you understand that, then why would you make the original comment saying “this should be called an air filter” since it most definitely is not one _by your own definition?_
@@tookitogo Water can be a "minute portion of matter" aka particle. Water can also be called a 'contaminate'. What is your point? A vent doesnt change the medium. A filter changes the medium.
That is a very poor quality vent
Why would you 3D print this when you could spot-weld some stamped sheet metal together? these kinds of vents aren't hard to assemble, and stamped sheet metal is one of the cheapest manufacturing methods in existence for high-volume parts.
Industrial solutions it's just a heat exchanger. Completely airtight/watertight. And has internal fans for circulation for the inside half of the exchanger. CNC machines in fab shops will be the most crusty disgusting thing you've ever seen. But the inside of their electrical cabinet is spotless because they have been using heat exchangers since the 60's on equipment.
0:27 water and air are both fluids? Oo
@@ized88 yes, they are
@sha_hito under "normal" circumstances like room temperature it doesn't really matter which definition of air you use (oxygen or atmosphere) it's a gas
@@ized88 a substance that has no fixed shape and yields easily to external pressure; a gas or (especially) a liquid.
Have a nice day 👍🏻

@@placek7125 just was looking for this comment
@@placek7125 they are.
He means fluid in an engineering standpoint. The air birds swim thru and the water fish fly in can both be represented as fluids in their equations.
Definition from Wikipedia: In physics, a fluid is a liquid, gas, or other material that may continuously move and deform (flow) under an applied shear stress, or external force.
@@team6612 thanks. Didn't know bro. Thou technically I understood what he meant.
Baffling.

Why us it that everytime we see your pfintfarm its all not working but when we see prusa print farm they are always working.....is it because you dont have any client's for working
It is because we take client privacy very seriously. Would you like use to film your proprietary products so all of your competitors can see them?
@@slant3d honestly a very sad excuse when you can just film while a row of printers has just started the bottom layers...
nothing to reveal in a single layer worth of plastic on a bed.
@@TheScarvig Is is really such a big deal? That's not what the core purpose of the video is. It's about the part in question.
@@jamiemacdonald436 a video can have many comment threads and this one happens to be a bit off topic....
i did not start it and i simply interacted with it because slant felt the need to defend himself with a shallow excuse
@@TheScarvig It’s a perfectly reasonable explanation, not a “shallow excuse”.
"Water and air are both fluids" ... ... ...
Yes, gas is a fluid. So what's your issue.
