3D printing method and device for bionic surface with mist collection and liquid drop control functions

The invention relates to the technical field of 3D printing, in particular to a 3D printing method and device for a bionic surface with mist collection and liquid drop control functions, and aims to realize preparation and adjustment of macroscopic and microstructure structures of an intelligent bionic surface with an efficient water collection function. The printing device comprises five hardware parts including a three-phase material supply system, a digital flow control extrusion system, an ultraviolet polymerization system, a three-dimensional motion platform and an intelligent control system. By combining the material design that the inner phase, the intermediate phase and the outer phase are not mutually dissolved and have the emulsifying and breaking capacity, according to optimization of process parameters, direct formation of the bionic spindle knot shape and real-time adjustment of the size and the distance of the spindle knot of the microfiber spindle are achieved, and the method has great applicat
