Abstract

A method for forming an object includes moving a recoat assembly () in a coating direction over a build material, wherein the recoat assembly () comprises a first roller () and a second roller () that is spaced apart from the first roller; rotating the first roller () 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 () 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 () positioned rearward of the front energy source, the second layer of build material within the build area.
