Jetting device with reduced crosstalk

摘要

A printing device (100) for jetting a liquid includes a flow path body (110) having a plurality of jetting flow paths, a liquid in the plurality of jetting flow paths, a piezoelectric actuator (125) associated with each jetting flow path, a feed substrate (160) having a plurality of fluid inlets (175), and a driver configured to apply a voltage pulse to the piezoelectric actuator (125). The first jetting flow path is adjacent to the second jetting flow path and a fluidic travel distance from the piezoelectric actuator (125) of the first jetting flow path to a nozzle (190) of the second jetting flow path is greater than a speed of sound in the liquid times the break off time of a droplet of the fluid from the nozzle (190).
