UM....

well im doomed... i guess i need to add some sort of air filtration in my printing room.. just to add some sort of protection.

 

well anything that emits a smell, is particle emission but not all are harmful. If you can smell it, your sensing those particles entering your body.

there have been other tests on the safety of 3d printing. Which talk about how safe the fumes are from 3d printing. all came to the conclusion that it was generally safe. These fumes are the same particle emissons these guys are talking about. I see no difference but its good to be cautious for your own well being.

"Moreover, ultrafine particles (UFPs: particles less than 100 nm) may be of particular importance for toxicity of fumes emitted from melting of some thermoplastics. For example, in a previous study of high temperature melting of PTFE at ∼480°C, UFPs with a count median diameter of 18 nm were produced, which were also shown to be highly toxic to rats (Oberdörster et al., 1995)."

looks like the ufp there talking about is the actual melting of the the filament during extrusion.

 

From the article:

Bolded emphasis mine.
So, yeah, 3d printing is as harmful as cooking. Something that millions of people spend ~1hr or more a day doing.
I think we'll be fine.
Either that, or I should set up an air scrubber next to my Wok.

 

they way the word that research makes it seem like they discovered something new.

 

Eggs are good for you..... Wait they are bad for you...... New research shows eggs are good for you...... And the debate goes on.
I am glad I moved my printer to the garage. Don't have to worry about this as much.

I'm sorry i didn't see the post here and opend a new one (maybe the admin will integrate it here?).

 

Did anyone consider that some of your fav fast food has plastic as a food source? Like some cheese on your pizza or your 2 minute noodles. Possibly is made of plastic according to some claims.

I do not think melted plastic is good to breath in. So some caution is in store. Anyone working on an enclosure?

I am more concerned that Fukushima is radiating the pacific and the world.

nope, because plastic is usually not digestable it comes out as it comes in, you would recognise this some times after eating

fukushima won't radiate the world, nor the pacific (unless there happens something new really bad)
at the time it's an horrible thing but local.

if you want to worry about some thing: poison in clothes, additives in food, cosmetics, plastic additives in food, hormones in the water, arsen, cadmium, lead, uranium in the water (some also in food because of industrial fertilizer)
or maybe that we have less and lesse usable antibiotics...
or global warming (this is of course more a future thing thant the others are).


back on topic: some have or had plans for enclosure, but open the window regularly should work as well.

 

Would an enclosure ever get too hot? What would the issue be using an enclosure? Considering that you have a heated bed, heated extruder. It would be like Saudi Arabia in the summer time in there.

Since the filament is hot and needs to cool, I wonder if there could be problems with melting and falling or warping?

it gets warm depends on how close it is.
but warping should be no problem, that's why you have a heat bed after all, that it stays hot
but it could bend (PLA) if it gets to hot.

so maybe you need a cooling system oder fresh air inside
make a search vor enclosure in the forum

 

I heard every time you print a yoda head it takes 2 hours of your life.





(3 if you use high quality with supports)

 

Sweet, I've never printed a Yoda head - I'm gonna live forever!

 

That means you better start printing some Chuck Norris heads to turn back the hands of time.
