Abstract: A method includes providing a reservoir of randomly oriented fibers in a solution, dispensing the solution of randomly oriented fibers through a nozzle having an orientation component onto a porous substrate as a solution of aligned fibers, and immobilizing the fibers to form a fiber pre-form. A system includes a porous substrate, a deposition nozzle, a reservoir of randomly oriented fibers in solution connected to the deposition nozzle, the deposition nozzle position adjacent the porous substrate and connected to the reservoir, the nozzle to receive the randomly oriented fibers and output aligned fibers, and a vacuum connected to the porous substrate to remove fluid from the porous substrate as the deposition nozzle deposits the aligned fibers on the porous substrate to produce a fiber pre-form having aligned fibers.

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.

Abstract: A method of atomizing a fluid using a pair of counter-rotating rollers including a first roller having grooves, the grooves enclosed by a pair of fins extending away from the first surface and a second roller having channels, the first and second rollers aligned with each other such that the grooves of the first roller mate with the channels of the second roller forming enclosures and nips. The method includes drawing the fluid from a fluid source through the nips, the nips having an upstream side and a downstream side, stretching the fluid between the diverging surfaces of the pair of counter-rotating rollers on the downstream side of the nips to form fluid filaments, and forming fluid droplets from the stretched fluid filaments on the downstream side of the nips between the diverging surfaces of the pair of counter-rotating rollers.

Abstract: An atomization device including a pair of counter-rotating rollers, a fluid source configured to coat at least one of the rollers in a feed fluid, and a baffle unit. The counter-rotation of the rollers stretches the feed fluid into a fluid filament between the two diverging surfaces of the rollers. The stretched fluid filaments breaking into a plurality of droplets at a capillary break-up point of the feed fluid. The baffle unit introduces a baffle fluid within the interior of the device, the baffle fluid transporting formed droplets of the feed fluid from the atomization device. Excess or misguides atomized fluid droplets are collected by the baffle unit and are recycled back into the device for use in later atomization processes. The variation of atomization device parameters allows for the selection of droplets having desired physical parameters.
