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. Furthermore, the present invention can prepare the models with various shapes according to different application scenes, and regulate the interface wettability performances of the models.
