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.

    I used it in a project 5 or 6 years ago, and my experience was basically this. It’s strong in the direction of the layers but brittle between layers. Works great for some applications, but I’d definitely experiment with it before committing to use it on anything where the strength of the print matters because it’s really only useful in two dimensions.
