Abstract: An apparatus and method of delivering a functional material is provided. The apparatus includes a pressurized source of fluid in a thermodynamically stable mixture with a functional material. A discharge device having an inlet and an outlet is connected to the pressurized source at the inlet. The discharge device is shaped to produce a collimated beam of functional material, where the fluid is in a gaseous state at a location before or beyond the outlet of the discharge device. A beam control device is positioned proximate to the outlet of the discharge device such that the collimated beam of functional material is controlled after the collimated beam of functional material moves through the outlet of the discharge device.
