Abstract: In the formation of a solid object by progressively adding extruded materials to a workpiece, a mechanism is disclosed for transposing the paths by which two or more extrusion nozzles travel to deposit materials. Paralleling a surface contour of the object being formed, the paths for two or more substantially continuous extruded traces are directed in complementary fashion to cause a first extrusion trace to form the object surface while a second extrusion trace is deposited behind the first trace. At another position along the surface contour, the paths of the extruded traces may cross over one another to allow the second extruded trace to define the object surface. Where the first and second traces have a different color or visual appearance, the disclosed mechanism enables fine graphic features to efficiently be integrated into the surface of the object being formed.

Abstract: The present disclosure relates to graphene. In particular, the present disclosure relates to a method for continuously preparing thermally conductive graphene films. A graphite oxide containing 40-60 wt % of moisture is directly stripped at a high temperature; and then, procedures such as dispersion, defoaming, coating, stripping, trimming, and reduction are performed to prepare thermally conductive graphene films with high thermal conductivity coefficient and strong electromagnetic shielding effectiveness. In the method, because of directly stripping the graphite oxide containing 40-60 wt % of moisture at a high temperature, the procedure of drying the graphite oxide is omitted, achieving low energy consumption and low manufacturing costs. Compared with preparing slurry by directly dispersing the graphite oxide, the concentration of the slurry after high temperature stripping is higher, and can reach 3-20 wt %.
