Spray forming is a materials processing technology in which a bulk liquid metal is converted to a spray of fine droplets and deposited onto a substrate or pattern to form a near-net-shape solid. Benefits include property improvement through rapid solidification of metals, near-net-shape fabrication, and process simplification through the elimination of unit operations. The Idaho National Engineering Laboratory has developed a unique spray-forming method, the Controlled Aspiration Process (CAP), to produce near-net-shape solids and coatings of metals, polymers, and composite materials using de Laval nozzles. The application of this technology for the production of tooling and microelectromechanical systems is described.
