Problems solved by technology

Although in recent years, the printing of materials with certain flexibility has been realized by shortening the feeding stroke of the printer, temperature-controlled printing, etc., the printing raw materials, such as TPU and TPE, are essentially solid linear materials, and it is impossible to realize printing based on multi-liquid components. Integrated rapid preparation of biomimetic variant actuators formed by solidification of different materials

Abstract

The invention discloses a 4D printing method and device and application of the device. The 4D printing method comprises the processes of multi-viscosity liquid component proportioning, flow mixing, defoaming, proper-temperature curing, filling, final curing and the like, and preparation of a bionic self-driven deformation structural body (bionic variant driving body for short) based on pneumatic flow driving is realized based on an integral forming design concept. According to the device and the method, the elastic and flexible material functional part with the primitive material in the viscosity range of 2,000-38,000 cps can be prepared, the preparation process of the bionic variant driving body is greatly simplified, direct printing and one-time forming are achieved, and secondary machining is not needed.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a 4D printing device and method for bionic functional structures. Background technique [0002] In recent years, biomimetic actuation structures based on flexible materials have been applied in many fields. Compared with traditional rigid structural devices, the bionic drive structure has the advantages of large deformation, multiple degrees of freedom, low cost, high flexibility, safe interaction, etc., and has better adaptability to unstructured environments. According to different driving methods, it can be divided into pneumatic flow drive, electric drive, electromagnetic drive, chemical reaction actuation, etc. Among them, the bionic self-driving deformation structure driven by aerodynamic flow (hereinafter referred to as "bionic deformation driving body") has the advantages of large load output, reliable motion, and repeatable work for a long time, and has hig...
