This is what I’m talking about: www.novintrades.com/articles/241 When cutting either CF or fiberglass, one should be wearing PPE to protect the skin and lungs, yet we have people printing CF infill and sanding it down without as much as a warning on the filament box. I’m not an expert on this topic, but as a hobbyist, I find it interesting how little is known or warned about the safety of materials we’re using for printing.

Yeah, I mean wear the PPE. You should honestly do that if you’re cutting anything that creates dust. Carbon fiber filament is really hust carbon fiber reinforced though. For example PLA-CF or PETG-CF is still a plastic filament, but it has tiny slivers of carbonfiber in it to give it more structure and rigidity. I assume that makes it less dangerous because the fibers are trapped in the plastic. I agree that there could be more awareness of safety. For instance I wonder how many people don’t realize that polycarbonate prints with toxic fumes and needs to be done in an enclosed printer with an air filter. Or ABS, for that matter. I like PETG cause there are no fumes. It doesn’t even have a smell. PLA printing smells like waffles with syrup to me, but PLA fumes aren’t toxic. Its physical properties are weaker than PETG though
