<p>My residential materials expert referred me to these links (<a href="http://www.bofaamericas.com/3D-printing-fume-extraction.asp" rel="noreferrer">3D Printing Fume Extraction Solutions</a>, and <a href="http://www.3dprintfilemarket.com/140629194058.html" rel="noreferrer">ABS 3d Printer Nanoparticle and Chemical Exhaust Air Filter</a>) and thinks that you're pretty much on track with the idea of using activated carbon.</p>

<p>We both primarily print with ABS with my Replicator Dual and what's worked enough for me (in the past 5 years) is to keep my printer next to a window or vent in my den at home. The window is obviously a good ventilation option, but the variability that it creates in the ambient temperature screwed with my prints. Later, I moved my machine into its own hutch, which, if it is an option, would greatly help the overall environment for both the machine and any stored filament.</p>

<p>We'll keep poking around, but hopefully that helps in the mean time.</p>

<p>It depends on how often you use your printer, meaning how many particles does your printer emit for time-unit. If you print nonstop with 5 printers then it's a different situation, opposite to one print per week.</p>
<p>Best material for passive filtering is carbon foam. It has the ability to capture chemical fumes. See this <a href="http://www.freedrinkingwater.com/general-health/air/diff-types-of-air-filters.php" rel="nofollow noreferrer">filter comparison</a>.
Having an enclosure with such a filter would be a good start.</p>

<p>I have to say that I don't know the particle size of 3d printing emission and how good the filtering ability of carbon foam is.</p>
<p>A step above is to bind such an enclosure bundled with an air purifier.</p>
<p>The best option would be laboratory equipment. But it is the most expensive one. It is designed to filter toxic vapours, fumes, gases and particles.</p>

<p>I have looked into this a lot. Especially when I had a phd chem engineer girlfriend who kept talking about how the fumes might give me cancer.. Frankly the system you need just costs too much. Lab equipment can run 20k easily. Not to mention the noise. What you really need is a backyard shed, but as one who lives where it snows I understand that is rarely a realistic option.</p>

<p>The Buzzbox looks cool and there are other brands. However their prices are usually as much as a flashforge, and usually cannot even hold a flashforge. 
More importantly there are parts where you can DIY your own. 
300 for a plexiglass case that can only hold a mini printer is not good enough by far.</p>

<p>Take a product <a href="http://www.3dprintclean.com/scrubber-filtration.htm" rel="noreferrer">like this air scrubber</a> Or build your own this like <a href="http://www.instructables.com/id/Build-a-laser-cutter-fume-extractor/" rel="noreferrer">this hard core one</a> designed for a laser cutter.</p>

<p>The local hackerspace should have a large laser cutter. Plastic should run 100 - 200 depending on how thick of a sheet you want. I personally buy scrap pieces. Designing a square box, adding hinges, then coating the edges with silicon sealant. Evacuate the chamber when done printing. Also should double as a heat chamber.. </p>

<p>For me, I can easily run 5 printers at a time. So I might take a metal Cabinet, seal it up. test it with a fog machine. Cut out a hole for the evacuation hose, and wire up camera. But I am far from having that much free time.</p>

<p>Also if I manage to make it air tight it should reduce fire hazard.</p>

<p>Taking that laser cutting fume extractor. There is nothing that will perform better than that. I hear you might get some smell, but that was in regards to laser cutters. </p>

<p>Rather than vent any air outside the printer enclosure, this will recirculate the air within, constantly running the air through the filter while at the same time conserving the heat needed for ABS prints. It's simple, and you can employ more than one of these or, using my design files, extend the size of the cabinet to stack more layers of carbon filtration material.

I built my own enclosure using plexiglass and some open-source mating pieces to assemble it, and sealed with clear tape.  So, any enclosure that would keep air from escaping should work.  As for recirculating the air and normalizing temps, I'm not sure that it makes that much difference.  The biggest thing was just having the enclosure to help with that.  Any air movement can cause cooling of the filament during a print, which can be desired or not desirable depending on the filament type and what you're printing.

I would try one of those cylindrical carbon filters that growers use, these are not that expensive so probably worth a try. Have been using those for apartment ventilation for some time now and they appear to be pretty good at removing smells.

Apologies!  I'll edit my question right now.  The question revolves around the emissions that printing can give off and how to filter the emissions out of the air.  As an example, printing in ABS emits styrene which is potentially carcinogenic.  So to filter the styrene out of the air, a fan can be added to the enclosure to pull the air out of the space and filter it.  Please let me know if you would like any other information to make this more clear.
