Abstract
The object of the invention is the provision of methods and apparatuses for controlled direct printing of continuous films or discreet structures using a two-component liquid jet issuing from an orifice. The two liquids may be miscible or immiscible, and form an annularly propagating flow along the axis of a deposition head. The flow consists of an outer sheath liquid with a boiling point temperature that is approximately 10 to 40 degrees lower than that of an inner sample liquid. The exit channel of the head is heated so that the pressurized outer sheath liquid is raised to a temperature greater than the boiling point of the sheath liquid at the local atmospheric pressure. The outer liquid is evaporated as the jet exits the orifice and falls at atmospheric pressure. Deposited sample line widths are produced in the range from approximately 1 to 1000 microns.
