Abstract: The present invention provides a method for electrohydrodynamic jet printing curved piezoelectric ceramics. First, a stable pressure is provided for a piezoelectric ceramic slurry to ensure that the slurry flows out from a nozzle at a fixed flow rate, and at the same time, an electric field is applied to the piezoelectric ceramic slurry at the nozzle to form a stable fine jet; then a curved substrate is fixed on a fixture of a curved substrate six-axis linkage module to ensure that the curved substrate is always perpendicular to the jet of the nozzle and keeps a constant distance from the nozzle during a printing process; fine jet drop on demand is realized through cooperative control of the changes of the curved substrate six-axis linkage module, the electric field and a flow field, and electrohydrodynamic jet printing and molding of curved piezoelectric ceramics is finally realized.
