In this episode, we will be looking at fume evacuation from laser and 3D printers. As we will be unboxing the AC Infinity CLOUDLINE S4, Quiet 4” Inline Duct Fan with Speed Controller - Ventilation Exhaust Fan (see more here: amzn.to/2BTDZiV ) for use in our new shop. This is a super quite variable speed which moves 205 CFM (cubic feet per minute of air). This makes it worth while for use laser cutters and engravers, as well 3D printers especially SLA versions. Also at the end we will do a little PSA on the risks of Carbon Monoxide and ventilation so you will want to watch to end.

I sure am glad you talked about putting fresh air back into the room. I have read so many comments on other videos that this fan didn't work well or that fan didn't work well. The thing is, they were all trying to pull a vacuum on their house with it. The fans are not designed to do that. It's one thing if you have your laser in the garage and you open your garage door and turn on your extractor fan and you having your laser stuck in the spare bedroom and trying to exhaust the fumes. The latter isn't going to work because there is no air coming back into the house.

I'm over it. I built a metal laser box with a 6 inch duct on top with the Cloudline 400 CFM pulling it out a window. I tried adding a 4 inch fresh air fan (Cloudline) into the box. No, still a lot of smoke smell. Closed that off and I left about a third of the box open in the front with a fan gently blowing the smoke to the back of the box for extraction. That kind of worked, but still so much smell. Yes, I have a window cracked in the back of the shop for both tests. I have a large shed shop I build guitars in. I would NEVER have a laser in my house. I'm at my wits end and sending the laser back. I am now feeling sick with sore throat, headache, etc. Oh, I was also wearing a respirator mask with the two round filtration cartridges as well. These lasers are not safe for your health unless you have a really good system to extract/filter the smoke. The thing is, nothing is out there for these desktop lasers. Well, nothing good. Those crappy enclosures they sell couldn't extract any smoke with tiny computer fans. Funny how xTool markets these lasers showing no enclosures or dust extraction. Also, they don't show the smoke they make, especially when cutting wood. I wish I had known. Now fighting with them to get a full refund as they want to keep 500 bucks for returning it. Costly mistake. These desktop lasers are so dangerous not just for smoke, but for your eyes and fire danger. Be careful, people!

@faisalabdi6350 8 месяцев назад

I have a fiber laser coming and was interest in getting this extractor. Just to clarify, If I have the laser in a room right next to the window, I should be able to set this up using the extractor right? take fume from the laser and send it out the window through the other end of the tube to get rid of dust/smell.

@chrisc6333 4 года назад

The Cloudline fans are fantastic - I setup a 4" one in my home work area for my small laser cutter and for things like solder fumes etc two months ago. Much quieter than cheaper quality similar fans and their support was great when I had some questions about which size to get before I bought one. In addition to your warning about carbon monoxide it is important that people know these type of inline fans are likely not rated as spark proof so may not be the best choice if you are venting anything that may be flammable such as a paint spray booth - a small hobby booth for airbrushing should be ok but for anything larger a blower type fan is a better choice.

@DIY3DTECHcom 4 года назад

Ah! Very good point on the spark proof! As part of my plan was a smaller desktop spray booth with a prefilter...

Can you get good air pull if you need to have a duct that's 40 feet long and 2 bends in the line

@innapropiator8024 8 месяцев назад

I made a construction to vent my printers, but it didnt make a difference due to odor. Is there a way to correspond, so I cound provide a picture? Maybe you could see what I should change within my construction. Cheers

@darknessfierce4209 5 месяцев назад

How do you bring more air in is setting a fan sufficient or is it just a matter of testing it?

@blewprent 2 года назад

But how to you clean the air before its vented outside?? Is there a system that can connect to the Cloudine, filters the air and then vents to outside?

@craftsmadepersonal1096 Год назад

Hello, can this be connected to a fume extractor to help pull out the smell? I have an omtech fume extractor, but it's hardly extracting the smoke & fumes.

@jeckjeck6943 3 года назад

Hello and thank you for your good advices. Can we talk now of how to filter toxic fumes before they go outside and polute our air ? ( sorry for my bad english).

@dallinpoulson2176 3 года назад

Maybe add a carbon filter on the tubing

@michelleulrich8929 3 года назад

Is this enough ventilation for a 50w laser cutting machine?

One point is really crucial : the diameter of hoses used to suck air and exhaust it. I just got an AC infinity s4 (205cfm, 10cm diameter) and du to adapters reducing the diameter of exhaust hoses, I have a HUGE loss of pressure, and it eventually sucks almost no air from the laser… do you have any ideas, advice or successful set up about that ? (Kind of length oh used, incidence of any curves or even the inner material of hoses to allow smooth flow of exhausted air) THANKS !! 🙏🏻🙏🏾

@electronron1 4 года назад

What are your thoughts on placing the inline fan as close to where it exits the building vs close to the laser engraver? I have heard that its best to pull the fumes through the duct rather than push them through the duct.

@DIY3DTECHcom 4 года назад

If you jump to 3:04 in the video you can see a teaser insert of my setup where this is the case (fan near exit point). As the idea is to creat a negative pressure area so yes :-)

@petercohen8877 4 года назад

Nice video. So if I want to make an enclosure for a 3D printer to suck out the fume, I need to install two fans rather than one? Where would be the best locations to install the fans?

@DIY3DTECHcom 4 года назад

just one of these and its perfect as you can spin it down. Remember you not trying to create a vacuum, just negative pressure in the box.

@NeoDemocedes 2 года назад

The attic fan in my house will blow out the pilot light on my water heater if I open the door to the basement while it's running... even with all the windows in the house open.

@BrickBazooka 3 года назад

Is it enough to carbon filter the room air with a airfreshener instead of venting out the fumes?

@reverse_engineered 3 года назад

No. A carbon filter will only absorb some chemicals, but not others. CO and CO2 gases will not be absorbed by carbon filters and can built up quickly in a room. Many materials including ABS and acrylic will also produce extremely toxic gases like HCN which will not be absorbed by a carbon filter.

@laurasimone9362 3 года назад

So would you recommend getting a second inline fan and pulling air in at the same rate? is it ok to have the air ventilation and intake mounted in the same window? I have a 1000 sq ft basement studio with a few mediums that need ventilation and I haven't had a problem with carbon monoxide yet but your video got me thinking... I have a studio glass kiln with built in ventilation (inside the kiln) that is near my water heater. I'm setting up a 3D resin printer on the opposite end of the basement and was planning on building duct with an inline fan into the window, maybe hooking it up to a closed cabinet to run the resin printer in. Up till now I've just opened the basement door to the backyard and put a fan by it to bring air in but that won't work for overnight prints or colder months...

@reverse_engineered 3 года назад

The air intake and exhaust have to be several feet apart. You can see an example of this if you have a newer furnace or hot water heater with a forced air draft; there will be two pipes going outside, with one a few feet above the other. If you put them too close, the air intake will suck in much of the dirty air that was being exhausted. You don't necessarily need an intake fan too, though it can help. As long as you have a low resistance path for air to be pulled in, the negative pressure caused by the exhaust will draw air in through that intake. But if you don't provide some kind of intake, the air will be pulled from whatever path is available. That could mean pulling air in around door and window seals or through chimneys. Typically, you want to have a bit of positive pressure if anything so that any remaining pressure pushes air out instead of drawing dusty air in. If it's in a garage or other similar room, it's not a big deal, but as DIY3DTECH pointed out, if it's in a room with a chimney, it will draw air in through the chimney, which you definitely don't want, so then it would be a good idea to use a dedicated intake fan. For the colder months, if you really wanted to get fancy, you could consider installing a heat recovery ventilator (HRV). This box includes intake and exhaust fans and a heat exchanger so that the warm air exiting can warm the cold air that is entering without the two air streams ever mixing. However, HRVs aren't designed to exhaust smoke and fumes, just stale room air. It would be fine for pulling air out of your kitchen when cooking or a bathroom, and would probably be fine for exhausting lingering fumes from a 3D printer, but you wouldn't want to pipe a laser cutter exhaust directly in to it or it would quickly be damaged. If you first put it through some significant filtering (furnace filters, carbon filters) to remove most of the soot and heavy particles, then the remaining gases could probably be exhausted through the HRV without too much trouble, but you would likely be voiding your warranty anyway.

@Case909 2 года назад

I'm shopping for a resin printer. If I use a grow tent along with fume evacuation system and carbon filter, would that be a good solution and allow me to safely work in the same room while the 3D printer is printing?

@MoDub18 3 года назад

I just bought a Anycubic Photon S and I'm asking myself if there is any risks of fire or explosion with the formaldehyde concentration of the printer and wash and uv curing station if I use a fan with the engine in the air flow. I tought I could use a bathroom ceiling fan but the company does not recommend using it to evacuate toxic vapors. My other option is a Franklin Electric 1 / 30hp @ 1550 rpm squirrel cage type blower with the engine outside the air flow coming from an old air exchanger but the shaft from the motor connecting to the barrel fan inside the blower tend to get hot a bit and I ask if it is enough heat to cause a risk of fire or explosion. I intend to use this venting system on a old re-purpose television cabinet sealed and equip with a plexiglass door having about 0,174645 square meter volume (15" x 27" x 29"). I know that's a lot of question but I want to make my 3D printing experience as safe as possible. Thanks a lot for a quick reply if possible I would like to build this unit during Christmas holyday. Love your video and the security concern you have about SLA printer. Sorry if my english is a bit bad I usualy speak french.

@DIY3DTECHcom 3 года назад

No worries with the English, with one printer I would not overly worry about explosion however you want negative ventilation and that will be be based on your room and/or enclosure. I would also recommend something purpose built such as the unit in the video rather then hacking something for safety reasons...

@ShyneflowLC 2 года назад

You got me nervous now. The room my laser will be in, is next to the room my water heater and furnace are in... Very close proximity to this small room. How much CFM is too much and becomes worrisome about drawing in the C02?

@shembree89 Год назад

He did the PSA right after talking about creating negative pressure so I would assume if you have the same flow in as out youre good. I'm not sure if just having an open window or similar would suffice though so I've been considering just getting two of these and having one for bringing air in??

@rayturp6742 Год назад

I use a 4” Inline Ventilation Fan with Speed Controller, and 4” Black Carbon Filter not venting outside. What do you all think?

@jonfitz3931 3 года назад

After making my own enclosure this is overkill. Make sure you get an air intake to make your fan work to its potential while protecting from laser light.

@martinmeechan1888 4 года назад

Have you seen the video titled “recycling cardboard into anything with 3D printing” you should watch it and try and recreate it

@DIY3DTECHcom 4 года назад

Are you speaking of the one where the kid puts cardboard in a blender and uses 3d printed molds? If that is the one yes, however seen it and it is pretty cool yet very time consuming. However I also came with my own hopefully easier version which if it works I will share soon.
