Abstract
The object of the invention is the provision of methods for controlled production of continuous multi-component filaments or discreet structures using a multi-component liquid jet issuing from an orifice. A multi-component jet consists of two or more liquids. The liquids may be miscible or immiscible, and form a co-axially propagating flow along the central axis of a flow cell. The working distance between the exit orifice and a substrate can be as large as 50 mm, so that in-flight processing of the jet is possible. The coaxial flow consists of an outer sheath liquid and an inner sample liquid or composite of liquids. The flow cell and the exit channel of the deposition head are heated so that the pressurized sheath liquid temperature is raised to near or above the boiling point of the sheath liquid at the local atmospheric pressure. The jet exits the deposition head through the orifice, and the outer liquid is evaporated as the jet falls at atmospheric pressure. The sheath liquid is processed thermally, optically, or chemically during flight to form a protective or insulating layer for the inner liquid or liquids. The inner liquids may contrastingly consist of an ultraviolet (UV) curable ink that is processed in-flight or after deposition. Since UV curable inks contain no volatile components, the coaxial jetted filament can be processed without producing cracks or bubbles in the sheath layer. Line widths are produced in the range from approximately 1 to 1000 microns.
