I think the question Steezy was getting at is, yes, those things are great. What kind of ventilation? Can I 3d print in the garage if the door is open? How much air is required to make it safe? Is there a simple way to lookup a material and make sure you're using the right safety precautions? Most materials seems to carry the "will cause cancer, sometimes, maybe, always" label. Is there a modern "maker" safety course, covering things like 3d printing, laser cutting, glues and paints, electronics, etc. that I can follow?
