Abstract

Traditional soft robots, which rely on multi-part processing and manual assembly, face inherent bottlenecks such as long manufacturing cycles, poor structural consistency, and difficulties in integrating complex functions. Leveraging its layer-by-layer accumulation and high design freedom, 3D printing technology provides a key solution for the one-step, integrated manufacturing of soft robots with complex internal distributed channels and functionally heterogeneous structures. This paper first systematically reviews various 3D printing technologies suitable for the integrated manufacturing of soft robots, along with their corresponding soft functional material systems. Finally, it discusses design strategies for integrated manufacturing, including holistic functional modeling, drive-structure integration, and multi-material topology optimization. By summarizing typical application examples of 3D printing-based integrated manufacturing of soft robots in fields such as machinery, biomimetic motion, and medical devices, this review highlights the significant advantages of integrated manufacturing in enhancing the performance, reliability, and functional integration of soft robots. Prospects for the development of smart materials and AI-enabled design are also presented.
