Very interesting, thanks for sharing your experience. But maybe this is the case for carbon fiber based filaments only (i.e. this is likely <1% of carbon-fiber as the use-case of 3D printing carbon fiber based hybrid plastic filaments is a new thing), and that most real-world carbon fiber is in the form of flat sheets whereby I doubt there are strands coming out.
