Beschreibung
Zusammenfassung:	A method of creating a sand mold for rapid casting, including the steps of determining a mold shape, providing a generally uniform thickness layer of sand, curing at least a portion of the layer of sand, machining the cured portions of the layer of sand based on the desired mold shape, and repeating the layer-forming, curing and machining steps until the sand mold is complete. Another aspect includes a machine for creating the sand mold having a build envelope defined by side walls, a movable build platform and at least one movable tool assembly, the movable tool assembly having a single or plurality of tools chosen from the group consisting of a sand dispenser, a sand leveling device, a curing device, and a machining device.
