摘要
4D打印技术是未来技术的先锋,主要原理是在3D打印技术基础上,以可变形材料作为驱动执行单元,利用材料的可变形特性,将成型构件的设计参数、成型工艺、变形行为和最终结构目标等信息设计到初始构型中。成型后利用外场激励介质刺激,通过弯曲、扭曲、膨胀等自我变形获得预设三维空间构型,是一种集成产品设计、制造、装配为一体的创新技术,即4D打印方法。本文主要探索4D打印的发展趋势以及变形机理,验证理论方法的正确性。
4D printing is a pioneer of the future technology, the main principle is based on 3D printing, deformable material as drive execution units, use of material deformation characteristics, design parameters and molding process of molding components, deformation behavior and the structure of target information such as the final design to the initial configuration. Using field stimulated medium after forming, bending, twist, swell deformation was a default configuration, three-dimensional space is a kind of integrated product design, manufacturing and assembly for the integration of technology innovation, namely 4D printing method. In this paper, we explore the 4D printing design and manufacture of rule and deformation field coupling drive mechanism, and the tiny metal droplet electromagnetic constraint component forming mechanism and forming process, using 4D printing principle to realize its manufacturing fonlaing, validating theory method.
