I didn’t find an SDS on PC Canada site for the house brand ABS. I didn’t look too hard they should supply one upon request. I did look at one for Makerbot ABS. I think it can be assumed all ABS will be similar.
The material is generally fine until it is heated. Fumes and dust are a hazard.The biggest red flag for me is there is inconclusive data of how much a Carcinogen it is. Depending on the lab it is somewhat, slightly or not proven.
The interpretation is at least my interpenetration is that the testing takes a long time and it is not yet complete. I work with chemicals every day for 30 years. I have many times watched chemicals go from non toxic, suspected, too toxic too really exceptionally toxic as data stacked up. Carcinogens are bad for that sometimes they take many years to surface often.
My advise is there is no reason to take unnecessary risks, enclose the printer (it prints better that way anyhow) and run a in line fan with dryer hose outside. There is no reason to have what is likely to be classed as a Carcinogen in your home. The micro particles from 3d printing are not well understood the most reasonable course is to take precautions. Oh gee I when overboard on that, is far better, than I wish I was more cautious. Cancer is not something you want to have.
