BTW, add a simple filter before your exhaust fan or the resins from cutting/engraving timber will stick to the fan blades and send them out of balance. You can make an easy filter with a few layers of garden fleece in a box - make sure you have access to replace or wash the fleece 😂
Don't have a laser. Yet. We are thinking of getting one and smoke is a worry. As going down the rabbit hole of research, I am now here. Thanks for the information and plans!
I used what was recommended to me by the plastics factory for this scenario. I am not 100% sure if it provides the same protection or not, but that's what they suggested. Might be worth doing your own research for some peace of mind 👍
Hi James, it's not based on a 720*720, but they could be easily modified to suit. We have had a subscriber make it to suit an 850*850 with no issues. Cheers!
Hi how are you!! I'm considering buying a diode laser cutting machine. However, I realized that caution is needed when dealing with MDF. Furthermore, I am wondering whether this precaution should be extended to other materials, especially since, regarding MDF, which is not widely discussed in Brazil, I had to seek information abroad. Although it is a topic that is rarely covered, I was concerned to discover that there is evidence that MDF may be linked to cancer, due to the gases that are produced during the laser cutting process. Unfortunately, I was unable to find information about the gases emitted when burning other materials, such as cardboard. Would you have any knowledge or information about this? Furthermore, I would like to know if there is some kind of exhaust cabin for this equipment, which is capable of filtering and cleaning these gases before they are released into the environment. Look at the answer I already had about this (if you're scared, just don't do it because everything in life causes some kind of harm to your health). Thank you in advance for your help and guidance. thanks ola tudo bem !!estou considerando comprar uma máquina de corte a laser de diodo.

My thoughts are that any fumes/sawdust is bad for you, so I use precautions regardless of the material, such as ventilation or a mask. I think it's important to mitigate the risk, no matter how small. We all want to be doing this for as long as we can!
Not a stupid question at all! The exhaust fan can on extract the same amount of air as it pulls in. If you have no air coming in, you have no air going out. Hope that helps!
Thanks for the great video! I'm curious: do you think a fan in place of the vent, to help draw air into the enclosure, would be a benefit to helping ensure no fumes sneak out?
I do not have a laser. But i am in the market for one. Annd as a maker the commercially available enclosures seem expencive for what they are. And i enjoy making things myself to fit my space
Thanks for the response! That’s awesome, and also a bit reassuring to hear. I received my laser two weeks ago and have been trying to get good ventilation since then. Purchased an enclosure from Amazon and a 4” inline fan but It still smells alot. But after seeing your design it’s clear that the one I got has a bunch of flaws!
OK good basic design except for one thing, you really want your extraction for the smoke and fumes at the bottom rather than the top, you are trying to suck the stuff away from the work and from the laser lens this is one reason why most laser beds such as honeycomb beds allow the fumes to be extracted from below .
BTW, add a simple filter before your exhaust fan or the resins from cutting/engraving timber will stick to the fan blades and send them out of balance. You can make an easy filter with a few layers of garden fleece in a box - make sure you have access to replace or wash the fleece 😂
Your very correct there. I have made that upgrade after a recommendation, we ended up using an aluminium fly screen mesh. Works week 👍
Great video. I have a CNC, don’t have a laser. Wanted to see how you built your enclosure and venting.
I am glad you liked the video! The enclosure construction and venting are very important for the health of your shop and yourself.
What is the name of red material used to block laser light
I am not 100% sure what it's called. I went to my local perspex company and asked for laser protection plastic.

They are a great addition to the workshop! Glad we could help! Thanks for watching!
How do you know what color plexiglass to get to,protect your eyes? I’ve seen green, red, orange…?
I used a speciality Laser Safety Window product from a local supplier. It is specially designed for the application.
@@kjh_woodworking Can you let us know what to get exactly. Everyone seems to kinda skip over this and it's probably the most important.
Why did you use perspexx and mot acrylic do they provide the same protection?
I used what was recommended to me by the plastics factory for this scenario. I am not 100% sure if it provides the same protection or not, but that's what they suggested. Might be worth doing your own research for some peace of mind 👍
Perspex is a brand name for acrylic. They are the same thing.
Question will these plans work on a 720x720m laser?
Hi James, it's not based on a 720*720, but they could be easily modified to suit. We have had a subscriber make it to suit an 850*850 with no issues. Cheers!
Whats the thickness of the material you used for the whole box? 1/2 inch?
I used 3/4, but that's only because it's what I had on hand. You could get away with 1/2.
@@kjh_woodworking Thank you sooooo much for your fast reply! :)
Not a problem at all! Glad I could help 👍

You said in the video you were going to put the plans in the description, I see nothing.
Sorry mate. Thanks for pointing that out. Check them out here - www.etsy.com/au/listing/1481825573/diy-laser-enclosure-build-plans
Nice video, where did you get the plexiglass for the laser? Thanks.
I purchased mine locally from a speciality supplier, but you can find them on Amazon also - amzn.to/3YTEUIe
May sound like a stupid question, but why does one need an input vent? won't that let smoke out once the fan is unplugged?
Not a stupid question at all! The exhaust fan can on extract the same amount of air as it pulls in. If you have no air coming in, you have no air going out. Hope that helps!
Thanks for the great video! I'm curious: do you think a fan in place of the vent, to help draw air into the enclosure, would be a benefit to helping ensure no fumes sneak out?
I haven't found much of an issue, but I also have quite a large fan being used. Possibly a good option if you were using a smaller fan.
@@kjh_woodworking Right on; thanks so much!
Looking to build an enclosure.
Awesome! Hope our video gave you some ideas 👍
Only problem with your enclosure is you cannot raise the laser when you want to use a rotary.
I hadn't even considered that. I'll keep that in mind for version 2!
Congratulations on the channel, very cool your videos success that like from mgf.
Cheers!

I couldn't agree more. If you build it yourself, you can make it exactly as you need it!
Thanks for watching mate!
Nice job!
Thanks!
Really nice build! 🙂
Can you still smell it or does it vent quick enough so that no fumes escape?
Thanks mate! Can't smell anything. The fan vents everything extremely well.
Thanks for the response!
That’s awesome, and also a bit reassuring to hear. I received my laser two weeks ago and have been trying to get good ventilation since then. Purchased an enclosure from Amazon and a 4” inline fan but It still smells alot. But after seeing your design it’s clear that the one I got has a bunch of flaws!
I think the key is cross ventilation. You need to make sure there is enough fresh air coming in as your extracting out. Hope that makes sense!
Nice job mate, looking forward to seeing more content 👍
Thanks mate!
I meant laser diode module for the engraver.
Love the design. Keep up the awesome content!
Thanks mate!
Great video thanks. BTW where did you get your laser shielding Perspex from?
Thanks mate! Fortunately, we were able to pick the shielding up locally!
I was looking for a diy Laser diode
That would be a cool project! Sorry, just an enclosure here 😊
Where can you find the eye protection sheet?
We were fortunate to be able to pick it up at a local Plastics supplier.
@@kjh_woodworking That's NO eye protection against a laser!
Nice, thank you ☺
No worries! Glad you liked it!
Mine will be here Friday
Nice! It's a great addition!

That's a fantastic point I never thought of. I'll keep that in mind for when I build version 2.0!
I’m watching because I want a laser and figured an enclosure would be good.
There a great addition to any shop! Thanks for watching!
Roundovers are for toilet seats only - chamfers every time 😂
Haha that's a hot topic in our workshop! I'm on the fence!
