Abstract

The invention discloses a surface acoustic wave-based shape memory composite member controllable deformation three-dimensional printing method. Two pairs of surface acoustic wave transducers are orthogonally arranged around a printing liquid tank, a photosensitive prepolymer formed by mixing a shape memory photosensitive material and silver nanoparticles is arranged in the printing liquid tank ina transducer working area, an ultraviolet light projection system is positioned below the transducers, ultraviolet light modulated with patterns is projected on the lower surface of the photosensitiveprepolymer, and a printing platform is arranged on an electric z-axis translation platform; and the surface acoustic wave transducers excite an ultrasonic energy field, the silver nanoparticles in the photosensitive prepolymer are linearly arranged under the action of sound field force, the ultraviolet light with the patterns is irradiated on the surface of the photosensitive prepolymer, a single-layer structure with complex silver nanowire patterns is obtained by selective area curing, and multi-layer printing is realized by lifting the z-axis platform. The method can realize manufacturing of a shape memory composite member capable of accurately controlling local deformation.

Description

technical field [0001] The invention relates to a controllable deformation three-dimensional printing method and device of rapid prototyping technology, in particular to a three-dimensional printing method and device of a controllable deformation region shape memory composite component based on surface acoustic waves. Background technique [0002] 3D printing technology targeting smart materials is emerging as a next-generation additive manufacturing technology that incorporates shape transformation into structural design and can reprogram printed objects in form or function under external stimuli. The intelligent composite components manufactured by this technology can respond to external stimuli such as light and heat, automatically change their shape and structure, and realize the functions of self-assembly and self-folding. [0003] The widely used manufacturing methods of intelligent composite components are multi-layer material bonding technology and three-dimensional ...
