A system and method for layer-by-layer production of an object is provided. The system includes a construction shape having a carrying surface adapted for carrying a layer of build material, a plate having a holding surface adapted for holding an object in an object build area, a moveable reservoir having a plurality of containment surfaces defining a containment area adapted for containing a volume of build material within the moveable reservoir, and an exposure unit adapted for exposing at least a portion of the layer of build material in the object build area so that the portion of the layer of build material solidifies to form a solidified layer of the object.
