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: Aerosols can be created by filament stretching and breaking of Newtonian and non-Newtonian fluids by applying a strain to and stretching the fluid. The fluid is stretched along a strain pathway and forms a fluid filament between diverging surfaces. The stretched fluid filament breaks into droplets that can be harvested to form a mist or aerosol. The aerosol creation systems can include one or more pairs of counter-rotating rollers that are positioned adjacent to each other that stretch the fluid or a pair of pistons that move toward and away from each other to stretch the fluid. Some aerosol creation systems can include multiple pairs of counter-rotating rollers that are positioned in a circular, oval, or linear pattern. The aerosol creation system with multiple pairs of counter-rotating rollers can generate mist is one or more directions and can be positioned between two concentric rings or linearly, among other configurations.

Abstract: A method of creating aerosols includes drawing a fluid from a fluid source through a first nip, the first nip defined between a first roller and an inner surface of a ring, the first nip having an upstream side and a downstream side, drawing the fluid from the fluid source through a second nip, the second nip defined between a second roller and the inner surface of the ring, the second roller positioned adjacent to and spaced apart from the first roller in a circular configuration, the second nip having an upstream side and a downstream side, stretching the fluid between diverging surfaces of the first roller and the inner surface of the ring on the downstream side of the first nip to form a first fluid filament, stretching the fluid between diverging surface of the second roller and the inner surface of the ring on the downstream side of the second nip to form a second fluid filament, causing the first fluid filament to break into a plurality of first droplets, and causing the second fluid filament to break into a plurality of second droplets.

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: An aerosol creation system includes a pair of counter-rotating rollers, a nip between the two rollers, the nip having an upstream side and a downstream side, and a pool of fluid on the upstream side of the nip, the fluid being drawn into the nip through the motion of the rollers, such that on the downstream side the fluid stretches between diverging surfaces of the two rollers and forms filaments that breaks up into droplets. A multi-roller aerosol creation system includes more than two rollers arranged to touch each other in a configuration, wherein areas where the rollers touch form nips, each nip having an upstream side and a downstream side, wherein the downstream side of the nips are positioned within a central space within the configuration of the rollers, and fluid surrounding the circular configuration, wherein an outer region of the circular configuration forms the upstream side of the nips.

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.
