Abstract
A method, system and apparatus for forming a three-dimensional object on a layer-by-layer basis involves forming a portion of the three-dimensional object using selective deposition modeling (SDM). SDM involves using at least one orifice, such as a jet, which dispenses a droplet of a flowable material that solidifies upon being dispensed. A drop volume capability of each orifice is adjusted until substantially all orifices have a uniform drop volume capability and all dispensed droplets of the flowable material have a uniform volume.
