This paper presents the design, fabrication, and performance test of a gap adjustable piezoelectrically-actuated DoD(drop-on-demand) molten metal injector for application to the 3D microstructure manufacturing or printed electronics. In the design process, we propose the gap adjustable mechanism of the piezoelectrically-actuated inkjet system to control the volume and velocity of the ejected molten metal droplets. In the experimental process, we fabricate the DoD metal injector and measure the volumes and velocities of the ejected droplets for molten metal as well as pure water to compare the ejecting performance for the different viscosity of ink and the operating temperature of the system.
