I'm just struggling to imagine how autonomous you could make a machine

effective dental filling type goo that cures under UV light or similar?
There are composite resins that will cure under UV; people have done that,
at least experimentally, for more orthodox composites work. It's also
conceivable to mix in a little bit of catalyst right above the nozzle.
I'd be surprised if there weren't people at least exploring doing both for
3D printing.
Getting the fibers to run in the desired directions, not just horizontally
within the printing layers, will be harder.
