What does it register with beer, wine and strong spirits? I need to know...As one or two of you may know, I do a bit of 3D printing here and there and for practical reasons the printer is in my study, it's a moderate room (15'x 7') and heated.
There's been a lot written about the dangers (real or perceived) about resin printers and the resin itself so I got a little curious after seeing some rather bizzare set ups people have for their printers, bio tents, forced extraction etc etc. Some Cannabis growers could learn a lot from these guys
It is a toxic material and you shouldn't drink it and avoid touching it, eye protection is recommended as well, but what about fumes, great if you can smell but I can't so I've no idea if there are fumes or not. In the end I took the plunge and purchased a TVOC meter, it's those that could be causing the most long term harm, the physical contact is easily dealt with by using appropriate PPE and common sense, but fumes?
Base values are, and there are many charts out there with slightly differing values so these are broad values.
<300 ppm is excellent and safe
<500 ppm is safe
>500 -1000 ppm it's okay but you should be ventilating
>1000-3000 ppm not good and needs lots of ventilation
>3000-5000 ppm very poor and requires forced ventilation
>5000 ppm you really should be looking at alternative options.
Of course duration of exposure is important and few tables list that, it should also be noted that nail varnish remover, white spirits and other house hold chemicals used daily by millions can easily be in the 2-5000 ppm bracket.
Anyway, to the crux, Saturn 2 with Siraya tech fast navy grey after a four hour print (resin is at peak temperature.

That's an open vat (of highly toxic material according to some), yet the gasses and fumes emitted are below the target 300 ppm or in the meters case 0.3mg/m³.
Suddenly I'm very much at ease with my printer in a domestic environment, however, I opened the tub of IPA to one side and with in 60 seconds the meter flipped out at a max 5000.
Now whether those fumes are harmful I've no idea, much like White spirits and Turps I suspect, or other house hold cleaners. Long term and constant exposure I'm confident they will be but short term two or three times a day for a few minutes? I've no idea.
Typically it takes me 60-120 seconds to clean a part ready for the UV station and it takes the room 20 minutes once the lid is back on to return to <300 ppm it'd be quicker if I opened a window, probably 2-3 minutes truth be told. A simple fan extraction would be useful but I'm loathe to drill big holes in walls.
There are lots of air quality meters on the market, ranging form £30 to £300, not all give you all the tests, this one is quite good as it measures several types of pollutant. If your concerned about printers and fumes then grab yourself one to put your mind at rest, but don't be surprised if ordinary things you've used openly for years flag up as unhealthy, Disaronno 3500 ppm, red wine 5000+ ppm, Gin 5000+ ppm
See the last paragraph of post #2639
Indeed, I'll do a test shortly in the shed when spraying celly, usually I have the window open and the booth vents outside, recently I just let it vent in the shed 18'x8' for a quick 2-3 min spray up, not the smartest move I admit but we often ignore our own safety but are very proactive about others....go figure. That's humans for you
Well if you're concerned my advice would be to keep the lid on the container and make sure you don't leave full glasses around to long to vent off
Just drink it quickly, TVOC's are a gas so the quicker it's inside you the less chance of it gassing off....or perhaps not
, now I have proof

Interestingly, IPA is often described as cleaning alcohol so it must depend on the base chemicals, the meter won't be able to differentiate between them so will just measure all of them.
For the record, Peroni is 180 ppm, knew it was cheap
I'd say that's not nice, it's a chemical so I'd expect it to have lots of TVOC of the bad type, yet I've just checked some Butanone and it's not registering at all, mind the bottle is about five years old so probably isn't Butanone any more
I think as a rule of thumb, if it smells it's probably not good.
Concur. I bought a TOCV meter as I was worried about the resins. As you say the meter stays in the safe readings.As one or two of you may know, I do a bit of 3D printing here and there and for practical reasons the printer is in my study, it's a moderate room (15'x 7') and heated.

Yup same for me, IPA sends the meter just crazy.
Greene King or Charles Wells ?
