Layered Structures of Metal Ionic Polymers, or Ionic Polymer-Metal Composites (IPMCs) are formed by a membrane of an ionic electroactive materials flanked by two metal electrodes on both surfaces; they are devices able to change their shape upon application of an electrical external stimulus. This class of materials is used in various fields such as biomedicine, soft robotics, and sensor technology because of their favorable properties (light weight, biocompatibility, fast response to stimulus and good flexibility). With additive manufacturing, actuators can be customized and tailored to specific applications, allowing for the optimization of performance, size, and weight, thus reducing costs and time of fabrication and enhancing functionality and efficiency in various applications. In this review, we present an overview of the newest trend in using different 3D printing techniques to produce electrically responsive IPMC devices.
金属离子聚合物或离子聚合物-金属复合材料（IPMC）的层状结构是由离子电活性材料的膜在两个表面两侧夹着两个金属电极形成的；它们是能够在施加外部电刺激时改变形状的装置。由于其良好的性能（重量轻、生物相容性、对刺激响应快和柔韧性好），这类材料被用于生物医学、软机器人技术和传感器技术等各个领域。通过增材制造，可以根据特定应用定制和调整致动器，从而优化性能、尺寸和重量，进而降低制造成本和时间，并提高各种应用中的功能和效率。在这篇综述中，我们概述了使用不同3D打印技术生产电响应IPMC装置的最新趋势。
