  • Patent number: 11652931
    Abstract: An MFD is disclosed. For example, the MFD includes a processor and a non-transitory computer-readable medium storing a plurality of instructions. The instructions when executed by the processor cause the processor to perform operations that include receiving an email, determining that a user wants to establish a connection based on the email, generating a reply email to the user, wherein the reply email includes an executable file that automatically configures an endpoint device of the user to establish the connection, transmitting the reply email to the user, and establishing the connection to the endpoint device of the user in response to execution of the executable file by the endpoint device of the user.

  • Patent number: 10710371
    Abstract: Exemplary printing apparatuses include, among other components, a printhead structure that includes nozzles adapted to eject liquid ink, a carriage assembly having positioning structures, and one or more printhead caps or cups within the carriage assembly. The carriage assembly is shaped to latch to the printhead structure. The printhead includes corresponding structures and the positioning structures engage with the corresponding structures when the carriage assembly is latched to the printhead structure. Also, the printhead caps are positioned within the carriage assembly so as to cover the nozzles when the carriage assembly is connected to the printhead structure.

  • Patent number: 10562211
    Abstract: A system for manufacturing a three-dimensional object facilitates the removal of support material from the object. The system includes a controller configured to move a platen to position the object at a position opposite a microwave radiator and then operate the microwave radiator to change the phase of the support material from solid to liquid. The controller either monitors the expiration of a predetermined time period or a temperature of the object to determine when the microwave radiator operation is terminated. The microwave radiation does not damage the object because the support material has a dielectric loss factor that is greater than the dielectric loss factor of the object.

  • Patent number: 10391712
    Abstract: A method of operating a cleaning system removes support material from parts made by a three-dimensional printer. The method operates the cleaning system to correlate data for features on a part located within a receptacle with structural data in a file used by the three-dimensional printer to fabricate the part. The method then operates one or more actuators to locate a fluid directing nozzle pneumatically connected to a pressurized fluid source opposite areas containing support material and operates the pressurized fluid source to enable pressurized fluid to be directed by the fluid directing nozzle at the support material. The method includes generating image data of the cleaned areas with an image sensor so the removal of the support material can be confirmed, and if an area is not sufficiently cleaned, the cleaning operation can be repeated.

  • Patent number: 10350873
    Abstract: A method of manufacturing a three-dimensional object facilitates the removal of support material from the object. The method includes forming at least a portion of a support for the object with support material containing nanoparticles of a material that readily converts microwave energy into heat. The object and support are moved to a position opposite a microwave radiator and the microwave radiator is operated to begin a change of the phase of the portion of the support material containing the nanoparticles before beginning a change of the phase of a portion of the support made from the support material alone. A controller either monitors the expiration of a predetermined time period or a temperature of the object to determine when the microwave radiator operation is terminated.

  • Patent number: 10118205
    Abstract: A system uses microwave energy to remove support material from a three-dimensional printed object with reduced risk of damage to the object. The system includes a microwave source, a three port device, a susceptor, a temperature sensor, and a controller. The controller operates the microwave source to direct microwave energy into a first port of the three port device, which emits the microwave at a second port of the three port device to irradiate the three-dimensional object and melt the support material. Reflected microwave increases as the amount of support material contacting the object is reduced and enters the second port of the three port device, which directs the reflected energy to the susceptor coupled to a third port of the three port device. The controller monitors the signal generated by the temperature sensor and deactivates the microwave source in response to a predetermined condition being reached.

  • Publication number: 20180001545
    Abstract: A three-dimensionally printed object includes build portions formed with a build material, first support portions formed with a first support material, and second portions formed with a second support material that is different than the first support material. The first and second support portions are arranged with the build portions such that the build portions are supported and protected during fabrication of the object. The arrangement is optimized to minimize a time period for removing the first and second support materials from the object and releasing the build portions. A method of producing the object includes operating ejectors of a three-dimensional object printer to form the build portion, first support portions, and the second support portions. The portions are formed with reference to the arrangement.
