[morcheeba]

There are two types of risks:

- epoxy sensitivity. Work with it too long (years) and you can become allergic. I can't tell if this system uses epoxy as a binder; it doesn't seem to because it would be messy.

- inhaling carbon fiber dust. This dust is made when you cut it, not when you lay it out. A 3d printer should put it in the right shape, so less cutting would be required. You'll want to avoid breathing it in, but it's not cancerous like asbestos: http://annhyg.oxfordjournals.org/content/38/inhaled_particle...
