  • Patent number: 11752554
    Abstract: According to aspects of the embodiments, there is provided method and system of using a roller-based deposition process to place two or more powders at some level of precision to build a multi-material, functionally-graded part. Instead of formulating a liquid ink by dispersing the powder feedstocks (metal or ceramic) in some binder-solvent mixture, there is detailed the use of two different types of fluid deposited in a digital manner on the roller surface. The two different types of fluids create a “wetted pixel” that can then capture a specific powder type with an affinity only to that fluid. Alternatives such as electrostatics, electrophotography, and the like are also provided to be used exclusively or with fluids to create an affine pixel to a particular powder type.

  • Publication number: 20230278104
    Abstract: A printer having a pump which includes an inner cavity which retains a liquid metal printing material, and a nozzle, where the nozzle is configured to eject a plurality of liquid metal drops, an actuation coil configured to supply a pulse to the liquid metal to generate an electromagnetic force upon the liquid metal, where the actuation coil supplies a pulse at a first time varying current pulse, where the electromagnetic force causes the nozzle to eject a drop of liquid metal. The actuation coil also supplies a pulse at a second time varying current pulse, where the electromagnetic force is not sufficient to eject a drop of liquid. A method for metal jetting in a printer is also disclosed where differences between the temperature in an upper portion of the pump and the temperature in a lower portion of the pump are minimized.

  • Patent number: 11747207
    Abstract: A system of optical sensors determines whether an object is placed on the system by passing light through the sensor layer, detecting light reflected from the object above the sensor layer, and identifying the object based on whether a color detected in the light corresponds to a color of the side of the object that is positioned on the system over the sensor layer. When the system includes multiple optical sensor units, the system may determine where the object has been placed by determining which of the sensor units detect light reflected from the side of the object.

  • Patent number: 11745268
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a wire detector to determine a position of a top surface of melted metal contained in a receptacle of a heated vessel in the apparatus from time to time. The solid metal wire being fed into the heated vessel is retracted and the length of the retracted wire is determined using a signal generated by the wire detector. The determined length of the wire is used to identify the position of the top level of the melted metal in the receptacle so the receptacle can be replenished if the level has fallen below a predetermined capacity for the receptacle.

  • Patent number: 11747796
    Abstract: The system and method described allow for real-time control over positioning of a micro-object. A movement of at least one micro-object suspended in a medium can be induced by a generation of one or more forces by electrodes proximate to the micro-object. Prior to inducing the movement, a simulation is used to develop a model describing a parameter of an interaction between each of the electrodes and the micro-object. A function describing the forces generated by an electrode and an extent of the movement induced due to the forces is generated using the model. The function is used to design closed loop policy control scheme for moving the micro-object towards a desired position. The position of the micro-object is tracked and taken into account when generating voltage patterns in the scheme.

  • Patent number: 11745265
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a liquid silicate application system to apply liquid silicate to a surface of a build platform prior to manufacture of a metal object. The liquid silicate layer is permitted to air dry and then the platform is heated to its operational temperature range for formation of a metal object with melted metal drops ejected by the apparatus. The liquid silicate layer forms a glassy, brittle layer on which the metal object is formed. This brittle layer is removed relatively easily with the object after the object is manufactured and the build platform is permitted to cool. The silicate layer improves the wetting of the surfaces of build platforms made with non-wetting materials, such as oxidized steel, while also preventing metal-to-metal welds with wetting materials, such as tungsten or nickel.

  • Patent number: 11738959
    Abstract: Alignment apparatuses include a frame and contact elements connected to the frame. The contact elements contact items that are to be transported in a processing direction relative to the frame. The contact elements are in permeant fixed positions relative to the frame, and do not move relative to the frame. Adjustable mounts are connected to the frame and move the frame in the processing direction and in a perpendicular cross-processing direction. A controller is electrically connected to the adjustable mounts, and the controller is adapted to control the adjustable mounts to simultaneously move the frame and all the contact elements in the cross-processing direction and the processing direction while rotating the frame. Methods laterally shift imaging on sheets that have had rotational correction performed by such alignment apparatuses.

  • Patent number: 11738574
    Abstract: A printing system comprises a printhead to eject a print fluid to a deposition region. Print media are held against a movable support surface via vacuum suction, and the movable support surface transports the print media through the deposition region. A vacuum plenum comprises a vacuum platen over which the movable support surface moves. The vacuum platen has platen holes that communicate the vacuum suction from the vacuum plenum to the movable support surface. An airflow restriction mechanism forms a high impedance zone in the vacuum platen, the high impedance zone comprising a subset of the platen holes. The airflow impedance through the high impedance zone is relatively high compared to the airflow impedance through another subset of the platen holes, which are part of a low impedance zone. The high impedance zone may be located near the printhead to reduce airflow through uncovered platen holes near the printhead.
