Abstract:
1. A system for layer-by-layer production of an object comprising: a construction shape comprising a carrying surface adapted for carrying a layer of build material; a plate comprising a holding surface adapted for holding an object in an object build area; a plate positioner engaging the plate, wherein the plate positioner is configured to move the plate in at least one of a direction substantially parallel to the object build area and a direction transverse to the object build area a moveable reservoir comprising a plurality of containment surfaces defining a containment area adapted for containing a volume of build material within the moveable reservoir; wherein the moveable reservoir is adapted such that the layer of build material is dispensed onto the carrying surface from the volume of build material within the moveable reservoir; wherein the moveable reservoir is moveable between a first position and a second position; wherein a portion of the carrying surface forms at least one of the plurality of containment surfaces of the moveable reservoir when the moveable reservoir is in the first position, and the portion of the carrying surface is positioned in the object build area when the moveable reservoir is in the second position; 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.
