    Abstract: A three-dimensional printing method is provided. The method comprises supplying a polymer composition to an extruder system and selectively dispensing the polymer composition through an extruder nozzle to form a three-dimensional structure. The polymer composition comprises a plurality of reinforcing fibers embedded and distributed within a thermoplastic polymer matrix, wherein the thermoplastic polymer matrix constitutes from about 20 wt. % to about 90 wt. % of the composition and the reinforcing fibers constitute from about 10 wt. % to about 80 wt. % of the composition.

    Abstract: An impregnation section and a method for impregnating fiber rovings with a polymer resin are disclosed. The impregnation section includes an impregnation zone and a gate passage. The impregnation zone is configured to impregnate the plurality of rovings with the resin. The gate passage is in fluid communication with the impregnation zone for flowing the resin therethrough such that the resin impinges on a surface of each of the plurality of rovings facing the gate passage and substantially uniformly coats the plurality of rovings. The method includes impinging a polymer resin onto a surface of a plurality of fiber rovings, and substantially uniformly coating the plurality of rovings with the resin. The method further includes traversing the plurality of coated rovings through an impregnation zone. Each of the plurality of rovings is under a tension of from about 5 Newtons to about 300 Newtons within the impregnation zone.

The impregnation section includes an impregnation zone configured to impregnate the roving with the resin and a gate passage in fluid communication with the impregnation zone for flowing the resin therethrough such that the resin coats the roving. Additionally, the impregnation section includes a surface disposed upstream of the impregnation zone in a run direction of the roving for contacting the roving. The method includes traversing at least one fiber roving over a surface, flowing a polymer resin through a gap, the gap being in the range between approximately 0.1 millimeters and approximately 4 millimeters, coating the roving with the resin, and traversing the coated roving through an impregnation zone to impregnate the roving with the resin.
