Abstract: An additive manufacturing process includes creating an aerosol from a powder at a spray generator, charging the aerosol to produce a charged aerosol having a first charge, forming a blanket charge on a deposition surface having a second charge with an opposite polarity from the first charge, selectively removing regions of the blanket charge, leaving charged regions on the deposition surface, and transporting the charged aerosol to the charged regions to form structures on the charged regions from the charged aerosol.

Abstract: An additive manufacturing system has an aerosol generator to aerosolize a powder, a deposition surface, a surface charging element to apply a blanket charge to the deposition surface, a charging print head to selectively remove portions of the blanket charge from the deposition surface, and a transport system to transport the aerosol powder from the aerosol generator to the deposition surface, the transport system having an aerosol charging element to apply charge opposite of the blanket charge to the aerosol powder. An additive manufacturing process includes creating an aerosol from a powder at a spray generator, charging the aerosol to produce a charged aerosol having a first charge, forming a blanket charge on a deposition surface having a second charge of an opposite polarity from the first charge, selectively removing regions of the blanket charge, and transporting the charged aerosol to the charged regions to form structures on the charged regions from the charged aerosol.
