Abstract
A heated apparatus, positioned in the X, Y, and Z directions, for forming fine lines of molten material on a substrate. The apparatus includes a pen having a refractory tip wetted with material in a molten state. The tip is attached to a V-shaped heater to form a heater assembly. The ends of the V-shaped heater are welded to the pins of a three lead TO-5 package base. The pen is then mounted on an apparatus adapted to direct writing. To that end, the pen is attached to a supporting device capable of moving in the X, Y, and Z directions. When the welding point of the tip/heater assembly reaches the melting point of the material to be deposited, it is dipped in a crucible containing the material in a molten state. The welding point nucleates a minute drop of the molten material, forming a reservoir. A thin film of material flows from the reservoir and wets the tip, which is then brought in contact with the substrate upon which the desired pattern is to be formed.
