Abstract: A printing head assembly with integrated purge mechanism is disclosed. The printing head assembly comprises: (a) a liquid dispensing head comprising one or more dispensing nozzles enclosed in a nozzle plate, driven by at least first and second pressures, and (b) a shielding mask including an opening in front of the one or more nozzles, wherein the opening being configured such that when printing liquid is dispensed from the head driven by the first pressure, the liquid being dispensed in pulses through the opening in the shielding mask, and (ii) when purge printing liquid is dispensed from the head driven by the second pressure, the liquid being drawn to a capillary gap formed between the shielding mask and the nozzle plate thereby removing the purge printing liquid from the nearby nozzles.

Abstract: A method of printing is provided where printing is using a first printing unit having redundant nozzles. Then, the method may include stopping the printing with the first printing unit while continuing the printing with active nozzles of a second printing unit. The method may include inspecting the first printing unit and identifying faulty nozzles, then designating the faulty nozzles as inactive and designating inactive nozzles of the first printing unit as a new active nozzle. According to some embodiments the method may include moving the first printing unit to an inspection zone prior to inspecting while continuing the printing with active nozzles of a second printing unit and moving the first printing unit back to the printing zone after inspection and continuing the printing with the first printing unit.

Abstract: Ti ink compositions for printing, such as ink jet printing, are disclosed. The ink compositions comprise a liquid dispersion of Ti hydride powder having a mean particle size of less than 10.0 microns; a liquid carrier; and at least one surfactant. Methods of making and using the disclosed inks are also disclosed. For example, a finished Ti product can be produced by printing the disclosed ink composition, such as by ink jet printing, to form a green article, heating the green article to dehydrogenate it and form a Ti containing part. The method may further comprise sintering the Ti containing part to produce a sintered Ti product. In an embodiment, the method comprises printing one or more support materials for the ink composition, that comprises solid particles of a metal oxide, a metal carbide, a metal nitride, a polymer, or combinations thereof.

Abstract: Embodiments of the invention are directed to a method of printing lines. A method may include positioning a plurality of print units according to a predefined spacing parameter. A method may include depositing material on a substrate by a plurality of print units to form a respective plurality of parallel lines according to a predefined spacing parameter. A printing unit may be positioned at an angle with respect to a predefined scan direction such that a predefined width of a printed line is achieved. A substrate may be rotated between scans such that a plurality of lines in a respective plurality of directions is printed in a scan direction.
Abstract translation: 本发明的实施例涉及一种打印线的方法。 一种方法可以包括根据预定义的间隔参数来定位多个打印单元。 一种方法可以包括通过多个打印单元在衬底上沉积材料以根据预定义的间隔参数形成相应的多条平行线。 打印单元可以相对于预定扫描方向成一角度定位，使得实现印刷线的预定宽度。 衬底可以在扫描之间旋转，使得在扫描方向上打印在相应多个方向上的多条线。

Abstract: A printing device for dispending material on a heated substrate is provided. The device may include a printing head having one or more nozzles and a heat shield that partially masks a side of the printing head that faces the heated substrate when printing so as to reduce heat transfer from the substrate to the printing head. The shield includes a slot aligned with the one or more nozzles to enable passage of material from the one or more nozzles to the heated substrate.
