Polymeric nanocomposites are materials of great interest to achieve physicochemical properties absent in polymer matrices. They consist of nanomaterials (eg nanoparticles) dispersed in polymer matrices. [1] Whilecomposite materials are manufactured by special methods that allow control of the incorporation of the reinforcement, the nanocomposites can be manufactured by polymer processing methods such as mixing / extrusion. [2] However, these methods produce isotropic materials whose properties are not necessarily those required by the application. The development of plastic parts using 3D printers type FFM (fused filament molding), [3] requires the manufacture of filaments based on nanocomposites but the deterministic way of building the piece allowsthe use of non-isotropic filaments in which only the surface exposed is that of the nanocomposite. In the present work a method of manufacturing filaments based on polymeric nanocomposites that allows to control the degree and distribution of the nanomaterial is described.
