https://patents.google.com/patent/US9156205B2/en strands of fiber are glued together with a plastic melted filament extrusion. the plastic is kevlar or nylon. The desing can be improved by combining it with the Stratasys Heated chamber patent for an even stronger part. Melted plastic bonds better to its previous extruded cooler self, that is kept at its glass transition phase with a heated chamber.
