ABSTRACT:
A method for aligning multiple nozzle members in a solid free form build unit is disclosed. A geometric test shape having at least one investigational topographic region projecting outward from a central base is formed and analyzed for at least one physical characteristic correlative with nozzle member targeting accuracy. The physical characteristic is at least one of color hue shift, surface pattern irregularity, and dimensional accuracy.
