Abstract
An object fabricating apparatus is comprised of at least one charged powder cloud generating system, at least one electrode proximate to the powder cloud generating system and comprising at least one shaped slot, and a voltage supply in communication with each electrode to electrostatically modulate the flow of charged powder to a conductive substrate electrically biased to provide an electrostatic attraction of the charged powder to the substrate. An object fabricating method is also disclosed that uses the object fabricating apparatus.
