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

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.

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.

Abstract: A dip-coat binder solution comprises a metal dip-coat powder and a dip-coat binder. The dip-coat binder solution has a viscosity greater than or equal to 1 cP and less than or equal to 40 cP. The metal dip-coat powder may comprise a stainless steel alloy, a nickel alloy, a copper alloy, a copper-nickel alloy, a cobalt-chrome alloy, a titanium alloy, an aluminum alloy, a tungsten alloy, or a combination thereof. A method of forming a part includes providing a green body part comprising a plurality of layers of print powder, dipping the green body part in a dip-coat binder solution to form a dip-coated green body part, and heating the dip-coated green body part. After dipping, the dip-coated green body part has a surface roughness Ra less than or equal to 10 ?m.

Abstract: A dip-coat binder solution comprises a dip-coat metallic precursor and a dip-coat binder. The dip-coat binder solution has a viscosity greater than or equal to 1 cP and less than or equal to 150 cP. A method of forming a part includes providing a green body part comprising a plurality of layers of print powder and a print binder, dipping the green body part in a dip-coat binder solution, and heating the dip-coated green body part. The dip-coated green body part is heated to form a coated green body part having a metallic precursor coating on an outer surface of the coated green body part. The coated green body part has a strength greater than or equal to 10 MPa.
