Current Status of Liquid Metal Printing

This review focuses on the current state of art in liquid metal additive manufacturing (AM), an emerging and growing family related printing technologies used to fabricate near-net shape or fully free-standing objects. The various modes droplet generation techniques as applied metals are discussed. Two different modes, continuous drop-on-demand (DOD), exist for based commercial inkjet technology. Several stages development from laboratory testing, prototyping, full commercialization. Printing include by piezoelectric actuation impact-driven, electrostatic, pneumatic, electrohydrodynamic (EHD), magnetohydrodynamic (MHD) ejection, application a high-power laser. impetus was precise, often small scale, jetting solder alloys microelectronics applications. fabrication higher-melting-point objects has provided further motivation research printing.
