A fabrication method comprises selecting an initial drop pattern defining a position of drops of a formable material, the initial drop pattern comprising a grid pattern of drops, designating the drops of the grid pattern to be dispensed by a first series of nozzles of a dispenser based on a spacing between drops in the Y-dimension; generating a modified drop pattern by shifting the grid pattern in a first direction along the Y-dimension, wherein a shift distance is selected such that the drops of the shifted grid pattern are designated to be dispensed from a second series of nozzles of the dispenser; dispensing the plurality of drops according to the modified drop pattern onto a substrate; during the dispensing of the drops, shifting a position of the stage or dispenser along the Y-dimension opposite to the first direction by an amount equal to the shift distance.
