Abstract: The disclosed spray deposition systems and methods use spray charging and discharging techniques to assist with digital deposition of spray droplets on a substrate. For example, the disclosed systems and methods have a charging system that generates spray droplets from a spray generator and charges the droplets. Focusing electrodes help to collimate the droplets into a tight droplet stream and, optionally, steering electrodes help direct the tight droplet stream. A charge removal system neutralizes or removes the charge from the droplets, either during the deposition of the droplets on a substrate or after the droplets have been deposited on a substrate.

Abstract: A method of forming lightweight structures from particle networks includes functionalizing edges of particles of an anisotropic material, exfoliating of the particles to form sheets of the material, aligning the sheets of material to form a network of multi-layered and aligned particles, and forming a structure out of the network of particles. One example uses graphite powder mixed into 4-aminobenzoic acid for edge functionalization, and exfoliation occurs with sonication in a solvent. The resulting particles undergo alignment with an aligning nozzle that also dispenses the aligned particles to form a structure.

Abstract: A method of creating a three-dimensional object includes generating a spray from a fluid by stretching the fluid between two diverging surfaces into a fluid filament until the fluid filament breaks into a plurality of droplets and forms the spray, entraining the spray in a carrier gas flow, directing the carrier gas flow toward a target surface through a multi-nozzle array, and repeatedly applying the carrier gas flow on a target surface to form the three-dimensional object by controlling the direction of the carrier gas flow toward the target surface.

Abstract: Polymer spray deposition systems and methods are disclosed that can be used with a wide range of thermoplastic materials to produce high resolution objects having the complexity and structural integrity typically only achieved using more traditional manufacturing techniques, like injection molding processes. The polymeric spray deposition systems and methods use a spray generator that stretches the fluid between two diverging surfaces, such as two rollers or between two pistons. The stretched fluid breaks apart into a plurality of droplets and is guided through a delivery system, that can include an optional droplet size selector, and into a multi-nozzle array. The multi-nozzle array is controlled and directs the spray onto a target surface, thereby creating a three-dimensional object. The disclosed polymer spray deposition systems and methods can be used in three-dimensional print heads and printing techniques.
