提出了一种磁性凝胶材料的4D打印系统，用于软致动器的制造。4D打印机是最近开发的一种工艺，不仅可以打印出三维结构，还可以同时打印出打印结构中的变形。我们提出的方法利用分散有磁性颗粒的凝胶材料作为起始材料。我们可以在增材制造过程中设计打印物体的每个部分的磁各向异性，以便打印结构可以在施加的磁场下变形。在本文中，我们展示了两种仿生实例，蠕虫型软驱动器和人工纤毛阵列的打印系统。第一个例子可以在狭窄的缝隙中爬行。第二个可以再现异时波，这是一种在自然小生物体上发现的相位传播波。这些演示表明，所提出的打印系统可以输出可变的仿生软致动器。
The authors proposed a fabricating process for soft actuators, named 4D printing system for magnetic gel materials. 4D printer is a recently developed process that can print out not only a 3-dimensional structure but also deformations in the printed structure at the same time. Our proposing process utilizes a gel material dispersed with magnetic particles as a starting material. We can design magnetic anisotropy in each portion of the printed object during additive manufacturing so that the printed structures could deform under an applied magnetic field. In this paper, we demonstrated 2 kinds of biomimetic examples by this printing system, a worm-type soft actuator and an array of artificial cilia. The first example could crawl in a narrow gap. The second one could reproduce a metachronal wave, which is a phase propagation wave found on natural small organisms. These demonstrations show that the proposed printing system could output variable biomimic soft actuators.
