Patent number: 11673406Abstract: Method of printing fluid on a printable surface of a substrate. A print head ejects fluid in a continuous stream. The print head that includes a micro-structural fluid ejector, which consists of output, elongate input, and tapering portions between the output and the elongate input portions. The output consists of an exit orifice of an inner diameter ranging between 0.1 ?m and 5 ?m and an end face having a surface roughness of less than 0.1 ?m. The print head is positioned above the substrate with the output of the micro-structural fluid ejector pointing downward. During printing, the print head positioning system maintains a vertical distance between the end face and the printable surface of the substrate within a range of 0 ?m to 5 ?m, and the pneumatic system applies pressure to the fluid in the micro-structural fluid ejector in the range of ?50,000 Pa to 1,000,000 Pa.Type: GrantFiled: March 20, 2019Date of Patent: June 13, 2023Assignee: XTPL S.A.Inventors: Filip Granek, Aneta Wiatrowska, Krzysztof Fijak, Michal Dusza, Przemyslaw Cichon, Piotr Kowalczewski

Patent number: 11490526Abstract: A method of forming a structure upon a substrate is disclosed. The method comprises: providing a substrate upon a surface of which a plurality of electrically conductive pads are disposed; depositing fluid containing a dispersion of electrically polarizable nanoparticles onto the substrate such that at least a portion of a first one of the plurality of pads is in contact with the fluid; applying an alternating electric field to the fluid using a first electrode and a second electrode, the first electrode being positioned so as to provide an effective first electrode end position from which the electric field is applied, coincident with the deposited fluid, and spaced apart from the first pad by a distance, and the second electrode being in contact with the first pad, such that a plurality of the nanoparticles are assembled to form a first elongate structure extending along at least part of the distance between the effective first electrode end position and the portion of the first pad.Type: GrantFiled: August 1, 2019Date of Patent: November 1, 2022Assignee: XTPL S.A.Inventors: Piotr Kowalczewski, Aneta Wiatrowska, Michal Dusza, Filip Granek

Patent number: 11419219Abstract: A method for modifying an elongate structure including providing a fluid deposited onto the substrate, the fluid containing a dispersion of electrically polarizable nanoparticles and applying an AC voltage across a portion of the elongate structure so as to cause an alternating electric current to pass through the narrow section such that a break in the elongate structure is formed at the narrow section, the break being defined between a first broken end and a second broken end of the elongate structure, and then cause, when the break is formed, an alternating electric field to be applied to the fluid such that a plurality of the nanoparticles contained in the fluid are assembled to form a continuation of the elongate structure extending from the first broken end towards the second broken end so as to join the first and second broken ends.Type: GrantFiled: June 5, 2019Date of Patent: August 16, 2022Assignee: XTPL S.A.Inventors: Piotr Kowalczewski, Aneta Wiatrowska, Michal Dusza, Filip Granek
