UFP Emissions...

As of this week, "My Weeble, Your Wobble" gets moved to the garage. Oh well. It was nice to keep it by my desktop.

From reading that it sounds as though everyone who has a 3D printer in a non-vented room should fall over dead in a few hours.
Admittedly there are gasses and particles released but the same is so in the air we breathe everyday from all the pollution in the air
that we breathe 24 hours per day. What was missing from all the scientific data is how the output from a printer effects humans
not rats and mice. What concentrations are harmful to humans and whether having a printer or two in an average size room is harmful
to humans and harmful in what way. I think this is a subject that needs more study and one that we will be hearing more about in the
future. I do not intend to move my printer to the garage based on one report and the effects on rats and mice.

I would tend to agree with you about rats and mice; however, for me, I'm going to err on the safe side.

I look at it like this - I'm a Stage IIIB lung cancer survivor (well so far - 16 months and counting!) and I've got no plans to move my printers out of my office. If I thought the particulates they generate was of real concern, you can bet they'd be freezing their little asses off outside.

To put this study's figures into perspective, in a house 4 gas burners for an hour produced an average peak concentration of ultra fine particles 1500,000 (>10nm) and 720,000 (<10nm) in the kitchen and for a master bedroom two rooms of airflow away, the concentrations were 350,000 (>10nm) and 87,000 (<10nm) for a masterbedroom two rooms away.

In this printer study, the sum of the peak concentration of measured particles running 2 PLA and 3 ABS printers in the same room was ~298,000. Then ultra fine particles less than 10 nm was only 6,000.

To me this means waking up to the smell of bacon was worse for me than sitting in a room with a printer. I personally conclude the signficance of these particles to be very trivial as I would expect to see chefs dieing off if it was any more than trivial. At that point I don't know if I would care anymore since most of the chefs in the world would be gone.

I bought this air purifier for my room to clean the air. It works pretty well.

That's a good idea Jesse!

Everyone, I put this up because I don't want to be a filter. I tend to agree with the seemingly insignificant numbers - that they are insignificant; however, personally, I'm going to error on the side of caution - not only for myself but for my wife and my dog - which sleeps at my feet. I'm willing to bet you can suck up more and worse particulates living 2,000 meters east of Interstate 5 in California - with the adiobatic current pushing them up towards my place....but then again, any opportunity to have clean air is a good thing...

I'm not moving my printer, just because theres particles in the air doesn't mean it's deadly. I print with PLA, I highly doubt some plants will affect me

Come here, Let's test this theory.

It turns out that air quality monitors are available for about $200.

I put the air purifier right next to the print on the highest filtration. I'm sitting a few feet away and can't smell it.
