(54) RECOAT ASSEMBLIES FOR ADDITIVE MANUFACTURING SYSTEMS AND METHODS FOR USING THE SAME


(57) A method for forming an object includes moving a recoat assembly over a build material, where the recoat assembly includes a first roller and a second roller that is spaced apart from the first roller, moving the second roller above the first roller in a vertical direction, rotating the first roller of the recoat assembly in a counter-rotation direction, such that a bottom of the first roller moves in a coating direction, contacting the build material with the first roller of the recoat assembly, thereby fluidizing at least a portion of the build material, while the second roller is spaced apart from the build material in the vertical direction, and moving the fluidized build material with the first roller, thereby depositing a second layer of the build material over an initial layer of build material positioned in a build area.
