Publication number: 20240131594Abstract: A three-dimensional (3D) object printer has an ejector head with a single nozzle that is fluidly connected to a plurality of orifices in an orifice plate of the ejector head. An ejection of material through the single nozzle is emitted through the plurality of orifices simultaneously. In one embodiment, some of the orifices are oriented at an angle to an axis perpendicular to the orifice plate. This configuration enables a structure to be formed with a predetermined material density without needing to increase the ejection frequency significantly or requiring the printer to incorporate multiple ejector heads.Type: ApplicationFiled: January 2, 2024Publication date: April 25, 2024Inventors: Denis Cormier, Santokh S. Badesha, Varun Sambhy

Patent number: 11904388Abstract: A three-dimensional (3D) object printer has an ejector head with a single nozzle that is fluidly connected to a plurality of orifices in an orifice plate of the ejector head. An ejection of material through the single nozzle is emitted through the plurality of orifices simultaneously. In one embodiment, some of the orifices are oriented at an angle to a normal to the plane of the orifice plate. A splicer of the printer that generates machine ready instructions for operation of the printer identifies a standoff distance between the orifice plate and a surface onto which drops are being ejected to achieve a target drop spacing for the drops ejected onto the surface. In this manner, a material density for structure within a layer can be achieved without needing to increase the ejection frequency significantly or requiring the printer to incorporate multiple ejector heads.Type: GrantFiled: January 4, 2021Date of Patent: February 20, 2024Assignee: Additive Technologies LLCInventors: Denis Cormier, Santokh S.

Publication number: 20230249247Abstract: A three-dimensional (3D) printer includes an ejector and a coil wrapped partially around the ejector. The 3D printer also includes a power source configured to transmit voltage pulses to the coil. The 3D printer causes one or more drops of the liquid to be jetted out of the nozzle, and a substrate configured to support the one or more drops and advance along a path defined by one or more arcuate contours, where the one or more arcuate contours define a first layer of a strut. One or more struts are printed from the first layer of the strut to a node of each strut. The one or more struts are printed from a first layer to a node and combine to fabricate a lattice structure including one or more vertical struts and/or one or more angled struts wherein each strut intersects with another strut at a node.Type: ApplicationFiled: April 14, 2023Publication date: August 10, 2023Applicant: XEROX CORPORATIONInventors: Denis Cormier, Dinesh Krishna Kumar Jayabal, Daniel Cormier, Santokh S.

Patent number: 11565475Abstract: A method operates a three-dimensional (3D) metal object manufacturing system to compensate for errors that occur during object formation. In the method, thermal image data and dimensional image data of a metal object being formed by the 3D metal object manufacturing system is generated prior to completion of the metal object. Thermal conditions are identified from these data and compared to predetermined ranges corresponding to the identified thermal conditions to identify one or more errors. For identified errors outside a corresponding predetermined difference range, the method performs an error compensation technique. The error compensation includes modification of a surface data model, modification of machine-ready instructions, or operation of a subtractive device.Type: GrantFiled: April 10, 2020Date of Patent: January 31, 2023Assignee: Xerox CorporationInventors: David A.

Publication number: 20220184708Abstract: A three-dimensional (3D) printer includes an ejector and a coil wrapped at least partially around the ejector. The 3D printer also includes a power source configured to transmit voltage pulses to the coil. The 3D printer also includes a computing system configured to cause the power source to transmit the voltage pulses to the coil in intermittent bursts.

Patent number: 11254156Abstract: An approach to printing a nickel precursor ink on a wide range of substrates for electronics and magnetic applications is disclosed. The nickel ink reduces to elemental nickel following heating. The ink was printed using an ultrasonic aerosol printing technique. By sintering the nickel precursor ink in the presence of a homogeneous magnetic field, the reduced nickel complex formed continuously aligned nickel nanofibers axially aligned with the direction of the magnetic field. The fabrication of aligned interlayered nanofiber films provides opportunities to produce structures with enhanced isotropic electrical and magnetic properties. The resistivity of the film was found to be as low as 0.56 m?·cm, and the saturation magnetization was measured to be 30 emu/g, which is comparable to bulk Ni. Magnetic anisotropy was induced with an easy axis along the direction of the applied magnetic field with soft magnetic properties.Type: GrantFiled: April 18, 2019Date of Patent: February 22, 2022Assignee: Rochester Institute of TechnologyInventors: Chaitanya G.
