  • Publication number: 20220314541
    Abstract: An actuator assembly for distributing build material and depositing binder material in an additive manufacturing apparatus may comprise an upper support and a lower support spaced vertically spaced from one another. A recoat head actuator may be coupled to a recoat head and one of the upper support and the lower support. The recoat head actuator may include a recoat motion axis. The recoat head actuator effects bi-directional movement of the recoat head on the recoat motion axis. A print head actuator may be coupled to a print head and the other of the upper support and the lower support. The print head actuator may include a print motion axis. The print head actuator effects bi-directional movement of the print head on the print motion axis. The recoat motion axis and the print motion axis are parallel to one another and spaced apart from one another in the vertical direction.

  • Publication number: 20220314329
    Abstract: Additive manufacturing apparatuses are disclosed. In one embodiment, an additive manufacturing apparatus may comprise a support chassis including a print bay, a build bay, and a material supply bay. Each bay may comprise an upper compartment and a lower compartment. A working surface may separate each of the print bay, the build bay, and the material supply bay into the upper compartment and the lower compartment, wherein: the build bay may be disposed between the print bay and the material supply bay. The lower compartment of the build bay comprises bulkheads sealing the lower compartment of the build bay from the lower compartment of the print bay and the lower compartment of the material supply bay.

  • Publication number: 20220227046
    Abstract: A method for forming an object includes moving a recoat assembly (200) in a coating direction over a build material, wherein the recoat assembly (200) comprises a first roller (202) and a second roller (204) that is spaced apart from the first roller; rotating the first roller (202) of the recoat assembly in a counter-rotation direction, such that a bottom of the first roller moves in the coating direction; contacting the build material with the first roller of the recoat assembly, thereby fluidizing at least a portion of the build material; irradiating, with a front energy source (260) coupled to a front end of the recoat assembly, an initial layer of build material positioned in a build area; subsequent to irradiating the initial layer of build material, spreading the build material on the build area with the first roller, thereby depositing a second layer of the build material over the initial layer of build material; and subsequent to spreading the second layer of the build material, irradiating, with a r

  • Publication number: 20220227042
    Abstract: A recoat assembly for an additive manufacturing system includes a first roller support, a second roller support, a first roller disposed between and supported by the first roller support and the second roller support, a first rotational actuator operably coupled to the first roller and configured to rotate the first roller about a first rotation axis, and a first sensor mechanically coupled to and in contact with the first roller support, where the first sensor outputs a first output signal indicative of a first force incident upon the first roller.

  • Publication number: 20220227127
    Abstract: An apparatus includes a printing head (154) comprising jet nozzles (158) spaced apart from one another, where a distance from a first jet nozzle to a second jet nozzle positioned adjacent the first jet nozzle defines a jet-spacing, a printing head position control assembly includes a first actuator assembly (102) to move the printing head along the longitudinal axis and a second actuator assembly (103) to move the printing head along a latitudinal axis, and an control unit communicatively coupled to the printing head position control assembly. The control unit causes jet nozzles to dispense drops of binder (50) while the printing head traverses a first pass trajectory along the longitudinal axis in a first direction, indexes the printing head to a second pass trajectory along the latitudinal axis, and causes jet nozzles to dispense drops of binder while the printing head traverses the second pass trajectory along the longitudinal axis in a second direction.
