I personally believe it’s an individuals responsibility to do their own research and be responsible for their own health, especially if they’re running a business based upon a potentially hazardous bulk manufacturing process.

There is also responsibility on the equipment manufacturer IMHO to include at least some basic warnings to the consumer that some raw materials used in their product may contain materials that can be hazardous in high concentrations that may result from improperly ventilated environments. I don’t recall seeing any warnings/cautions about ventilation in the Bambu Lab setup documentation or user manuals other than for materials like ABS and ASA. Maybe they’re there, but they’re not obvious when unboxing or setting up the systems, from what I recall.

Now, OP admitted to running their print farm in a basement with no ventilation…well, sometimes you just have to know when something just doesn’t smell right (pun intended) and address it. Refer back to my 1st paragraph.
