• The mechanism of action of thermal bubbles at the solid–liquid interface was studied for the first time. • Unveiling the underlying mechanisms of liquid metal droplet ejection. • The potential of utilizing this technology to achieve multi-orifice liquid metal jetting was demonstrated. In this work, we introduced the pulsed laser-driven liquid metal arrayed printing technology. This study harnesses sub-millimeter-sized rapidly expanding bubbles generated by nanosecond pulsed laser irradiation at the solid–liquid interface as the power source for liquid metal printing, enabling efficient arrayed jetting printing of liquid metal. Utilizing high-speed imaging technology, this study investigates the expansion process of bubbles induced by nanosecond pulsed lasers at the solid–liquid interface and the jetting process of liquid metal, thereby revealing the mechanism of liquid metal jet ejection. The study systematically examines the influence of laser parameters on the jetting behavior of liquid metal, laying a theoretical and technical foundation for applications such as patterned printing in the field of liquid metal. This technology holds significant engineering implications for further advancing the application of liquid metal in fields such as flexible electronics and printed electronics. [ABSTRACT FROM AUTHOR]
