I just linked to one myself. MSDS is not something universal, every company has its own.
You replied to my previous comment where I said ABS fume not being "toxic" with "WRONG!".
The MSDS you linked to also just mentions that ABS "may cause irritation".
I don't understand how you can compare it to cigarette smoke, doesn't thermal decomposition happen there and harmful carcinogenic chemicals are created?
if anything, at this point abs fume would be as much of a toxic as alcohol, not cigarette smoke.
I'll admit that I don't know much about ultrafine particles, only that we still don't know much about their health effects, but I don't think you've provided any proof for claiming the opposite either.
A little more on topic: I guess the fan blowing the air out of the box is the best place for putting a filter?
"alcohol"? thats way toxic. lol thousands die each year from alcohol poisoning. we are talking about 'off gassing' from melting plastics etc. thats lots more unknown health effects than alcohol, Tobacco or oil smoke which all are known to be bad for health.
and companies/manufacturers dont just make up their own MSDS documents. they have to use 3rd party labs and regulated standards by places like NFPA, UL, safety codes etc. heck whats the use of them if a corporation could just say "oh its safe trust me"? I have spent most my 40 year career following these type safety laws and maintaining compliance with such codes. they are not just to hamper your desires to do whatever you want. they are to save lives and property destruction.
you sound like people that say "oh those traffic signals dont apply to me riding a bike, they are just for licensed vehicles. then they cruise right through a stop sign and wonder why they got ran over by cross traffic that didnt even have a stop sign. just use a little common sense and you may live longer.
I stated above what ill effects people in my home had as a result of 3D printing ABS fumes caused on prints of only an hour or so. and my home is not near as air tight as most. since it was built in 1960. and I only have 1 Solidoodle 2 printer. it took 3 days of no printing and air out home, for the blood red streaks to clear up in my eyes after just a couple days printing 1-2 items a day. I dont call that just irritation. so I got an air purifier also posted above. plus when weather allows I open a window nearby. I also intend to install a powered dryer vent exhaust to outside soon and connect it to inclosure of printer like I have on my air brush paint booth. like I stated above, NASA even took it serious for the space station 3D printer. also need to read that entire MSDS doc and you will see much more known and unknown hazards. plus its only referring to ABS in raw form. the other link is a lab study on what happens when heated and melted. they list more effects and again state there is more to be learned with additional studies. so like I stated already, since 3D printing in homes and offices is in its infancy still, regulations are still to come I am sure that will surprise you. and there are many other materials used in all types of 3D printing methods some of which already have known hazards much worse.
yeah I still print and prefer results using ABS. but being safe about it is not an option.
Solidoodle 2 with Deluxe kit cover & glass bed with heater. and 2nd board SD2 used not 3rd and alum platform not installed yet still wood. also need cooling fan installed to board. use Repetier Host couple vers. Slic3r also have all free ware STL programs
