摘要

The development of flexible electronics (FEs) has rapidly accelerated innumerous fields due to their exceptional deformability, bending, and stretchability.Room-temperature gallium-based liquid metals (LMs) are consideredas efficient conductive materials for FEs due to their outstanding electricalconductivity and intrinsic flexibility. Recently, 3D printing has become a promisingtechnique for fabricating FEs. However, the poor printability due to highsurface tension and fluidity offers huge challenges in the 3D printing of LMs.This review summarizes the effective strategies to address these challenges.It primarily focuses on three points: 1) how to improve the printability of LMand its wettability with the substrate, 2) how to select the appropriate printingmethod to improve the printing speed and ensure the resolution of printingstructure, and 3) how to provide perfect encapsulation for LM-based FEs with3D printing. Following a brief introduction, the mainstream printing technologiesand recent developments in the 3D printing of LMs are provided, with anemphasis on the selection of printing method, improvement of printability,encapsulation, and conductivity activation. Then, the revolutionary changesattained after 3D printing of LMs are specifically focused upon. Finally, opinionsand potential directions for this thriving discipline are explored.
