Good video! Your intuition about the vent holes is correct. The textbook term for it is Conservation of Mass. To maintain the same velocity on the way in, you want vent holes that equal the size of the exhaust. Smaller holes will result in higher velocity and vice versa.
I built an enclosure with similar materials but fir a 60w jpt mopa which means its a rectangle on its end rather than on its side. Where would I place the small holes on a box this shape? Wherever I put the holes, the fan will ventilation hole will be kn the opposite side? I tried researching conservation of mass on airflow but I couldn't find much on it
Hello, don't know if you see new comments on older videos but thought I would ask if you have the STL file found for the 4 inch duct flanges. I found some online but yours look like its very good and saves a lot of filament unlike others I've seen. great video.
Hello Mate, thank you very much for that great tutorial. However, i was wondering if there was any way to coat the interior with something fireproof as sometimes (rarely), lasers could start flames and a wooden enclosure would only make it worse.
You could line the inside with fire resistant plasterboard. To slow down the spread of fire. There are also fire extinguisher add-ons from Xtool that you can add to any enclosure which seems to be a great alternative
I was wondering if anyone can help. I want to build this but cant find the acrylic sheets anywhere the ones i purchased just came as a solid orange. Can you help
Considering a build like this myself. Got a small question though. Does all the smell get vented out well? Like if the laser hasn't run for a while, does the enclosure build up smell which then "blasts" you in the face if you open it up? I currently have a more expensive branded enclosure but not quite liking it as the smell is still bad. It vents out fine out of the window. But when not using my laser for two weeks and opening it up, a huge "cloud" of smell "punches" me in the base. It's like it still builds up inside the enclosure somehow.
The smell mostly builds up on the cutting bed below the material, that will stink from just 1 cutting project. It's a smelly process I don't think you can get around that to be honest. If I take out my cutting bed and just smell the enclosure itself it's not too smelly.
At 8:14 what is that fan thing you use? Did you buy it? Repurpose? I'm asking because I am currently useing an pre-owned kitchen fume hood extractor thing, and this looks a bit smaller
Hi Nik, im actually testing 2 fans at the moment for this enclosure, the one in the video is this - www.amazon.co.uk/dp/B01N3C7R4E just a cheap 4inch inline fan (approx 110CFM) and then I'm testing the AC Infinity T6 (6 inch, 400CFM). The 4inch does the job, and is very quiet, but this ac inifinty is much more powerful and I got it 2nd hand for not that much more than the 4inch so Ill probably keep the ac infinity
I like the simplicity of this enclosure. Looks great!
Excellent video ! Thank you for making and posting. Good luck with the cutter.
Great stuff. I got a hood thing but it still leaks a lot of smell even with air assist and a extraction fan. Need to build something like this
i came here for the enclosure, but was stoked to see the cameo by the digitakt in the background :)
Genius at work❤

Thanks for the info and clearing that up. Time to read up on conservation of mass 👍

Very useful, thank you ☺
You're welcome 😊
Hi
Where did you purchase the acrylic panel from?
Steve
How big is the amount of wood you got for this? I’m thinking of using project panels

Let me find them for you

Oh yeah very good idea ! Thank you
Do you know if there a smart way to stop the laser when we open the box? It's to avoid It would be to avoid blinding people in the event of a problem.
Yes you could install a cut off switch on the lid if needed
which fan did u used?
I was wondering if anyone can help. I want to build this but cant find the acrylic sheets anywhere the ones i purchased just came as a solid orange. Can you help
Do you have the plans for this. With the sizes
Hi, nice work. Where did you buy the orange acryl? Thank you.
From eBay, it's just standard acrylic\perspex

dude what arm are you using to hold your midi controller?
Humanscale M2
Nice! Where you did get the coloured acrylic sheet from ?
I just ordered perspex sheet from ebay. Its very easy to find.
I love it!!!
Where did you get the fan for the exhaust?
Acinfinity
If i didnt watch your video i was gonna make a huge mistake :D ty.

Hey bro I don't have a 3d printer any suggestion for printing exhaust pipes?
you could slice my design and try laser cutting 3-6mm plywood and stack them together to create the exhaust ports
Good video. Too bad the OD safety windows are so ridiculously expensive.
Yes, proper OD safety glass is hugely expensive, but worth the cost if it protects your eyesight, that's priceless
I think you wouldn't need those holes when you always use air-assist.
Do you have the plans available?
unfortunately not, its just a really simple basic box build
me want
Simple and cheap. Plus a couple of grand in tools tho. But shuuush
I think you wouldn't need those holes when you always use air-assist.

Yes you are probably right, its not air tight so you would get airflow through the enclosure even without the holes
