摘要：A printer system may include a coaxial extruder head that extrudes a core, abulk, and/or a core and bulk cladding to form complex structures without retooling. The
coaxial extruder head may include a distribution channel with an entrance and an exit, apriming chamber that surrounds the distribution channel. The priming chamber mayinclude an outlet and a first inlet, a heating element thermally connected to the primingchamber, and a nozzle connected to the outlet of the priming chamber. Further, thenozzle may converge from the outlet of the priming chamber to an orifice of the nozzle.In addition, the exit of the distribution channel may be disposed at the orifice of thenozzle. This structure facilitates extruding a core and cladding type composite from theextruder head.
