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 rear energy source (262) positioned rearward of the front energy source, the second layer of build material within the build area.

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 μm.

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.
