  • Patent number: 11731199
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus has a plurality of thermally insulative members that float in a volume of heat transfer lubricating fluid in which a X-Y translation mechanism moves to position a platform opposite an ejector. The apparatus also includes a housing having an internal volume in which the platform and X-Y translation mechanism are located. The heat transfer lubricating fluid can be a molten salt, such as a molten fluoride, chloride, or nitrate molten salt. The thermally insulative members can be spheres made of zirconium oxide or zirconium dioxide. The thermally insulative layer formed by the members floating in the fluid protects the X-Y mechanism while the housing helps keep the surface temperature of the object being formed on the platform in an optimal range for bonding of melted metal drops ejected from the ejector to a surface of a metal object being formed on the platform.

  • Patent number: 11736643
    Abstract: The present disclosure discloses methods and systems for managing multiple scan requests received at a multi-function device. The method includes receiving a scan request from a remote computing device of a remote user. Before executing the scan request, two conditions are checked. It is checked if document is present on a scanning platform of the multi-function device and further it is checked if one or more activities on a user interface of the multi-function device, are being performed. Based on the presence of the document on the scanning platform and the one or more activities on the user interface, the scan request received from the remote user is disallowed. This way, multiple scanned requests are managed at the multi-function device.

  • Patent number: 11731352
    Abstract: An additive manufacturing (AM) system manufactures composite structures having different materials in an integrated manner during a single processing process. For example, a first composite image is created on a substrate and then that image is stabilized by heat, pressure of chemical fusion not to the point of complete solid formation but enough to give the first composite image enough stability so that it is not disturbed by subsequent processing. A second image is then created on parts of the substrate not covered by the first composite image, a second powder is applied, and excess second powder that is not part of the second image is removed. The substrate may be cut into sheets that are stacked in register for consolidation and subsequent matrix removal resulting in a multi-polymer 3D object.

  • Patent number: 11731366
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus selects operational parameters for operation of the printer to form conductive metal traces on substrates with dimensions within appropriate tolerances and with sufficient conductive material to carry electrical currents without burning up or becoming too hot. The apparatus identifies the material of the substrate and the bulk metal being melted for ejection and uses this identification data to select the operational parameters. Thus, the apparatus can form conductive traces and circuits on a wide range of substrate materials including polymeric substrates, semiconductor materials, oxide layers on semiconductor materials, glass, and other crystalline materials.

  • Patent number: 11731349
    Abstract: Additive manufacturing processes featuring consolidation of thermoplastic particulates may form printed objects in a range of shapes. Nanoparticles disposed upon the outer surface of the thermoplastic particulates may improve flow performance of the thermoplastic particulates during additive manufacturing, but may lead to excessive porosity following consolidation. Excessive porosity may be detrimental for performance applications requiring high mechanical strength. A carboxylic acid-based sintering aid, particularly a metal carboxylate, may decrease porosity of consolidated parts following sintering without substantially increasing blocking in a powder bed. Particulate compositions suitable for additive manufacturing may comprise: a plurality of thermoplastic particulates comprising a carboxylic acid-based sintering aid admixed with a thermoplastic polymer, and a plurality of nanoparticles disposed upon an outer surface of the thermoplastic particulates.

  • Publication number: 20230259161
    Abstract: The present disclosure discloses a method and a system for securing a user interface (UI) panel of a multi-function device. The method includes activating a retraction assembly, based on one or more retraction triggering conditions. Once the retraction assembly is activated, multiple components of the retraction assembly start functioning. At first, the UI panel is moved to a first position. Next, the UI panel is moved from the first position to a second position. Then, the UI panel in the second position is retracted into the multi-function device to secure the UI panel inside the multi-function device. This way, the UI panel is secured inside the multi-function device. Later, the retracted UI panel may be moved out of the multi-function device. To move the UI panel outside the multi-function device, the retraction assembly is activated again based on the one or more protraction triggering conditions.

  • Patent number: 11724523
    Abstract: A printing system comprises an ink deposition assembly, a media transport device, and an airflow control system. The ink deposition assembly comprises printheads to deposit a print fluid, such as ink, on print media, such as paper, transported through a deposition region. The media transport device holds the print media against a moving support surface, such as a belt, by vacuum suction through holes in the media transport device and transports the print media though the deposition region. The airflow control system comprises a damper and an actuator configured to move the damper along a cross-process direction. The damper blocks airflow through a subset of the holes along a side of the media transport device, the subset varying based on a position of the damper. The damper is moved to change the subset of the holes blocked by the damper based on a size of the print medium.

  • Patent number: 11718107
    Abstract: A printing system comprises a printhead to eject a print fluid to a deposition region. A movable support surface, such as a belt, is used to transport print media through the deposition region, with the print media being held against the movable support surface by vacuum suction through holes in the movable support surface. A media registration device loads print media onto the movable support surface and registers the print media to a location of the movable support surface. The movable support surface comprises no-suction-regions in which the vacuum suction through the movable support surface is prevented. The no-suction regions extend across the width of the movable support surface in a cross-process direction and are arranged at predetermined intervals along the process direction. The control system causes the media registration device to register each of the print media relative to a respective one of the no-suction-regions.
