Well I'm not sure that candles are safe either. Also cooking with oil - especially in a hot Wok - will yield similar results.
So we may learn some day that working at mcdonalds near the french fry machine is really bad for your health but at this point I think we can assume it's probably safe. Or the risk of lung cancer is acceptibly low. Same goes for 3D printing. But only time will tell.
All 3 of these activities involve heating a hot oily substance (PLA is basically made from corn oil).

That article is just sensationalism, because it admits that the levels emitted from printing are similar to burning a scented candle.
I'm sure there's still a lot to learn about the safety of 3D printing, but that article doesn't contribute much to that quest.
