Abstract
A three-dimensional (3D) metal object manufacturing apparatus is configured to eject melted metal drops from an ejector head at different velocities to form different portions of metal object layers with different measurable values of a same physical property. The different velocities are achieved by operating the ejector head with two different electrical voltages. The greater voltage that achieves the higher velocity is about 25% greater than the voltage used to achieve the lesser velocity. By operating the ejector head with the two different voltages different portions of the object can be formed with different physical property characteristics.
