Abstract

The present disclosure relates to a 3D surface printing apparatus for the edge area of substrate, the apparatus including a jig part that erects the substrate and immobilizes it, a nozzle part that comprises a nozzle that ejects ink through Electrohydrodynamic (EHD) jetting by applying a voltage to an electrode, from above the erected substrate; a moving part that moves the nozzle left and right; and a control part that controls a printing operation, wherein the moving part prints a pattern that is continuously connected along a front surface of the rim of the substrate, a side surface of the substrate and a rear surface of the rim of the substrate as it horizontally moves the nozzle, and the control part controls the printing operation, considering changes in 3D electric field distribution.
