  • 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.

  • Publication number: 20230227680
    Abstract: Additive manufacturing processes, such as powder bed fusion of thermoplastic particulates, may be employed to form printed objects in a range of shapes. It is sometimes desirable to form conductive traces upon the surface of printed objects. Conductive traces and similar features may be introduced during additive manufacturing processes by incorporating a metal precursor in a thermoplastic printing composition, converting a portion of the metal precursor to discontinuous metal islands using laser irradiation, and performing electroless plating. Suitable printing compositions may comprise a plurality of thermoplastic particulates comprising a thermoplastic polymer, a metal precursor admixed with the thermoplastic polymer, and optionally a plurality of nanoparticles disposed upon an outer surface of each of the thermoplastic particulates, wherein the metal precursor is activatable to form metal islands upon exposure to laser irradiation. Melt emulsification may be used to form the thermoplastic particulates.

  • Publication number: 20230231961
    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.

  • Publication number: 20230221902
    Abstract: A processor of a printing apparatus obtains and maintains the media type of print media located in a media storage component of the printing apparatus. The processor also accesses a reference file containing different printing speed limits for different media types. The reference file can be maintained in an electronic storage component of the printing apparatus. The processor uses the reference file to determine an appropriate printing speed limit for a printing engine of the printing apparatus that corresponds to the media type of the print media in the media storage component. Further, a user interface of the printing apparatus can display an overspeed indicator, and/or the processor can stop the printing from occurring, based on a job-set printing speed of the printing engine being above the printing speed limit.

  • Publication number: 20230212405
    Abstract: Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles and a polymer material comprising at least one thermoplastic polymer and at least one thermally curable polymer precursor. At a sufficient temperature, the at least one thermally curable polymer precursor may undergo a reaction, optionally also undergoing a reaction with the piezoelectric particles, and form an at least partially cured printed part. The piezoelectric particles may be mixed with the polymer material and remain substantially non-agglomerated when combined with the polymer material.

  • Patent number: 11684972
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus has a thermally insulative layer between a platform on which an ejection head ejects drops of melted metal and a X-Y translation mechanism on which the platform is moved within an X-Y plane opposite the ejection head. The apparatus also includes a housing having an internal volume in which the platform and X-Y translation mechanism are located. In one embodiment, the thermally insulative layer is a plurality of spheres made of a thermally insulative material such as a ceramic made of zirconium dioxide or zirconium oxide. The thermally insulative layer 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 the ejected melted metal drops to the object's surface.

  • Patent number: 11685150
    Abstract: A coefficient of friction (COF) sensor on a carrier roll surface wetted with fountain solution transferred from an imaging member measures COF of the wetted carrier roll surface in real-time, even between or during printing operations. The transferred fountain solution may be concentrated and/or chilled to solidify before the measurement. The measured COF is used in a feedback loop to actively control the fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during an imaging or other printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.
