90W Laser Cutter From Scratch | Smoke Eater

- All laser cutters must have adequate ventilation for the fumes and smoke that they will produce. CO2 laser cutters produce smoke and fumes that can be hazardous to breathe. And since this laser cutter is in my basement, I will need to be extra careful about adequate ventilation. For these reasons, I'm taking the extra step of adding an active carbon filtration system before venting the exhaust out of a basement window. The activated carbon filter should also help with the smell associated with cutting wood on the laser cutter.
As part of my laser cutter's cabinet design, I included a chamber that will house the filtering system. This chamber will contain an air filter for large particles and an active carbon filter for smoke filtration. Two fans will draw air through the top of the cabinet. It will then pass through the air filter into the chamber to pass through the carbon filter before leaving through the window.
I first made a template to mount two 3D printed brackets to hold the carbon filter. I drilled holes and added brass inserts into the cabinet before mounting the brackets.
Next, I taped up the gaps around the smoke eater chamber. I used black duct tape that I measured and cut to length. I considered using something like a silicone sealant instead but decided that tape would be adequate for this job.
I designed a top lid and base for the air filter in Fusion 360 before cutting these parts on the Shapeoko out of 3/4" MDF. I painted these parts to match the cabinet. I cut to length three 1/4-20 threaded rods that will secure the air filter in place once the base fastens to the cabinet. I mounted the air filter base to the cabinet with wood screws and then attached the top with 1/4-20 wing nuts. I added one half of a Dryer Dock to the top lid. To finish off the air filter install, I designed, and 3D printed a magnetic hose adapter. I attached the dryer hose and the second part of the Dryer Dock to this adapter and installed it in the cabinet.
Next, I moved on to the carbon filter. I designed and cut a plug out of 3/4" MDF to fit the carbon filter's opening. I drilled pilot holes and used wood screws to secure the fitting in place. I then used another Dryer Dock in the plug to make the carbon filter detachable.
The last step in the build was to create a window for the front opening. Again I used Fusion 360 to design the window and used the Shapeoko to cut the piece from a 4mm acrylic sheet. I used the 2020 T-Slot aluminum extrusion to build a frame for the window. To create an airtight seal for the chamber, I added foam tape around the edges and cut away the excess. I then installed the frame in the opening using 2020 corner brackets and wood screws. The final step was to add 3D printed handles to the acrylic window and install the window on the frame with M5 bolts.
I'm delighted with the way the smoke eater turned out! A quick test reassured me that there are good airflow and pressure through the system. I will have to wait until the laser's completion before giving it a real test, but mission accomplished for now!
IMPORTANT: I AM STILL VENTING THE SMOKE OUTSIDE!! DON'T ATTEMPT TO USE THIS WITHOUT VENTING THE SMOKE OUTSIDE! EXHAUST FROM LASER IS DANGEROUS AND MUST BE VENTED OUTSIDE FOR SAFETY!
👇🏻 I MADE A NEW VERSION OF THE SMOKE EATER!! 👇🏻

I’m happy this build worked! I wasn’t sure it would have enough air pressure until I put it all together. :) Thanks for watching! Don’t forget to subscribe!
Love the cat checking to see if the filter cabinet will make a good spot to curl up in
Mr. O leaves no spot unchecked :)
Hi. Can you please show the complete set up from the laser up to the air filter if you don't mind? Would like to do the same thing. Thank you.
There is a rectangular vent hole at the back of the cabinet to the rear of the bed. This vent hole draws smoke down into the smoke eater chamber which is below the laser cutter bed. The air flows through an air filter and then a carbon filter and then through the inline fan and out of the window. Check out Smoke Eater 2.0 for a better look at the set up!
The screws on those hose clamps have a hexagonal outside shape. ;)
Yeah yeah :)
@@acwrightdesign don't laugh, it took me a decade to notice and i'm never going back to a screwdriver on those!
if a person is just patient, and does one little step at a time, it's possible to build amazing things! It's why hardware stores are so great. So you suppose everyone measures things as carefully as you do? (I noticed the cats stayed away from the cutter!)Thanks for another video PEW PEW!
Thanks for the support Tina!
No demo of how this works? I understand the build, but it doesn’t seem efficient enough for a full on laser.
The honest answer is I don't know if it will work. It is simply something I built into the cabinet in hopes it will work and I'm gonna give it a try. I'm still waiting to finish the laser build and if it doesn't work I will go to plan B which would be venting the smoke directly outside from the back panel of the laser with no smoke eater. I will try to include a demo in the final build video or a future video!
Hey A.C., great video (both this one and v2) I had not considered the type of carbon filter you used in your build. I'm curious what your thoughts on lifespan of the filter carbon. How long have you been using it and what kind of duty cycle/material are you running through your laser? And a TOTALLY random question - is that a Hackintosh in the background around 3:30? I have always wanted to build one on bare metal, but never have. Thanks again for the great content!
Thanks! I have not had the carbon filter long enough to give a good estimate on how long it will last. I will try to give an update in a future video!
The computer in the background is my Mac Mini. However, I did start with a Hackintosh a few years back which led me to adopting all Macs in my house :)
Hello
Thanks for the video, it's very informative. What kind of filament did you use on your Prusa for the parts?
Also, did you finally manage to test it? Do the filters elliminate odor from cutting?
Thanks
I use PETG to print most parts for the machine. The filters do eliminate the odor which is what I built the smoke eater to do. I can't say for sure it is removing all chemicals from the air so I still vent the air outside for safety.
@@acwrightdesign thankls a lot for you concise answer!
Would this stop you from having to vent outside? I hate venting all my cool AC air outside in the south, lol
I have found I still need to vent outside.
@@acwrightdesign hmm, im going to have to see how glowforge did there's I guess. Your videos are awesome btw!
@@myk3l9675 Thanks!
This is a great idea, how long do you anticipate or have experience related to the life of the filters whilst using the laser cutter? 1 year? 6 months? Life before cleaning or replacement?
@@acwrightdesign great stuff...cant wait to hear. Really would like to build this! Great idea and very neat!
I'm not sure. I will try and keep track of how long the filters last and give an update in a future video!
Thanks!
Nothing scratch about it. By the time I would get all the tools and machines one can just buy a descent filter
Yeah I guess scratch + tools
