Abstract

The devices, systems, and methods of the present disclosure are directed to spreader positioning techniques for consistent and rapid layer-by-layer fabrication of three-dimensional objects formed through binder jetting. For example, an additive manufacturing system may include a roller and a print carriage. In a layer-by-layer fabrication process, the roller may move in advance of the print carriage over a dimension of a volume to spread a respective layer of powder onto which the print carriage delivers a binder. Controlling the position of the roller may facilitate achieving consistent layer characteristics which, in turn, may facilitate fabrication of high quality parts.
