Abstract
This invention relates to a method and apparatus for creating a three-dimensional structure from a binder-free powder. A corona discharge (plasma) generator forms a controllable electric field, positioning the binder-free powder within the influence of the electric field generated by the corona discharge generator, and activating the corona discharge generator to attract the binder-free powder into a three-dimensional structure. The corona discharge generator includes a grounded bottom substrate and a top substrate elevated above the bottom substrate in a substantially parallel planar orientation. The binder-free powder is placed in the interstitial space between the bottom substrate and the top substrate. An electrode above the top substrate, in electrical communication with the bottom substrate and coupled to a voltage power supply, creates the electrical field. The resulting three-dimensional structure is formed far more rapidly than known additive manufacturing techniques.
