System & Method for Direct Fabrication of Micro/Macro Scale Objects in a Vacuum Using Electromagnetic Steering

This new materials processing technology allows metal and ceramic parts to be manufactured in three dimensions by additive deposition of material, either in atmosphere or in a vacuum. The scale is on the order of the powder size and can be as small as one micron. The deposition rate can be orders of magnitude greater than vapor deposition, which is the current vacuum fabrication technology for devices.
