I've been looking into this material due to the really nice surface finish and clean look (actually purchased some already 😅)
However I recently came across a video by CNC kitchen where he raised some potential health concerns relating to the fibers specifically inside the filament. One of the commenters mentioned they couldn't wash the fibers off their skin, and another likened it to the "3d printing equivalent of asbestos"
I don't plan to print with it just yet due to needing a hardened nozzle, and spare extruder parts. However when I do, i'm feeling a little worried about how safe it is - mainly whether the final printed part is fine for occasional skin contact, or whether this material should ideally be left to just cosmetic parts.

In theory it should be mostly fine to touch, idk much about it either unfortunately. it might be a good idea to put some sort of spray on sealer if you will be touching it regularly and are concerned about it at all.
It is definitely dangerous to sand or cut with a saw or something, definitely want to do that outside with gloves and a respirator because then you're getting loose fibers both on you and airborne.
