Abstract: The present invention provides composites with controllable superhydrophilic and superhydrophobic performances, a 3D printing method and 3D printed parts. The composites with controllable superhydrophilic and superhydrophobic interface performances comprise hydrophobic powder and/or hydrophilic powder and jointing phase powder, wherein the jointing phase powder is thermoplastic polymers. The present invention can print the parts with a continuous wettability change from superhydrophilic to superhydrophobic performances by regulating the mass percentage of the hydrophobic powder, the hydrophilic powder and the jointing phase powder.

Abstract: A lower surface of the printing platform is provided with a displacement device, and the displacement device is used to rotate the printing platform horizontally and adjust a pitch angle of the printing platform. The additive device is located above the printing platform and is connected to one end of the robotic arm, and the additive device is provided with a pressing roller. The robotic arm includes rotating joints used to drive the additive device to print and melt a fiber tow on the printing platform according to a predetermined path. The fiber pulling device is disposed on the printing platform to grab the reinforced fiber and make it cross-weave with the horizontally printed fiber tow on the horizontal plane. When working, the pressing roller is always perpendicular to the printing platform to press the melted fiber tow and the reinforced fiber cross-woven with the fiber tow.

Abstract: The present disclosure provides a superconducting power generation device and a power generation method. The device includes a superconductor, a conductive coil, a permanent magnet and a cooling medium. When ambient temperature is lower than its superconducting critical temperature, the superconductor, made of the second-type superconducting material, is capable of generating a magnetic levitation force to an outer permanent magnet and levitate it. When an external force is applied to the permanent magnet, its position changes compared to the conductive coil, which affects the magnetic flux passing through the coil and induces the generation of electromotive force in the coil, thereby converting mechanical energy to electric energy. By using the device provided by the present disclosure, the conversion from the mechanical energy to the electric energy in an ultra-low temperature environment can be achieved, and thus, problems about energy sources on low-temperature celestial bodies in extrasolar systems are solved.
