A method for efficiently producing closely-spaced parallel gridlines and perpendicular bus bar structures on a substrate during a single pass of a multi-nozzle printhead assembly over the substrate. A first section of the parallel gridlines is printed adjacent to one edge of the substrate while moving the printhead assembly in a first direction. The printhead assembly is then reciprocated in a second direction (X-axis) orthogonal to the first direction, whereby the extruded material forms a bus bar structure extending perpendicular to the gridlines. Movement of the printhead assembly in the first direction is then resumed to form a second section of the gridlines. The second direction reciprocation process is repeated for each desired bus bar structure. The entire gridline/bus bar printing process is performed without halting the extrusion of material (i.e., using a continuous bead). |
