摘要

This paper presents a novel design of an acoustic-wave liquid ejector by using PDMS soft-lithography. Both annular patterned lens membrane and piezoelectric transducer are designed to be replaceable to avoid ink clogging on the ejector surface. With the integration of an external siphoning system, the ejector is capable of jetting downward rather than only upward and refilling ink automatically without external force, which makes it suitable for 3D printing applications. By applying the electric signal at 2.4 MHz, the ejector can eject water downward with a speed of 0.29 m/s and droplet dimension of 720 μΜ.
