Abstract: A valve configured to control flow of a material therethrough includes a body having a bore formed axially therethrough. The valve also includes a cooler positioned at least partially around or within the body. The cooler is configured to cool the material to below a melting point of the material to form a solid plug within the body to prevent the material from flowing therethrough. The valve also includes a heater positioned at least partially around or within the body. The heater is configured to re-heat the material to above the melting point of the material to allow the material to flow therethrough.

Abstract: A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a printhead to eject a print fluid through an opening of a carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system is to flow air through the carrier plate to the movable support surface via a port through the carrier plate on an inboard side the carrier plate and to control a flow rate of the air flowed through the port based on a size of a print medium transported by the media transport device.

Abstract: 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.

Abstract: A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes monitoring operating parameters of a component in the MFD, calculating a life set point for the component based on the operating parameters, and changing a default life set point for the component stored in a memory of the MFD to the life set point that is calculated based on the operating parameters.
