摘要： 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.
