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.

If you want a high-strength part and you have carbon fiber and a 3D printer, what you want to do is 3D print a mold and then apply the carbon fiber and resin to it by hand (either laminated or "forged").
Here is an alternative Piped link(s):

This is different from carbon fiber filament.
The filament is impregnated with short strands of carbon fiber (aka chopped strand,)
Basically, what you’re doing is using a 3d printed part as a core to shape the carbon fiber- which is a very useful trick- similar to shaping pink insulation foam and skinning that over. (Pink foam is fairly lightweight and very easy to shape- a resistive wire or wire heat gun cuts like butter. Especially useful if you take copper power wire and bend it to form.)
