Modelless sand mold and core formation for rapid casting.

摘要

Determining a mold shape; forming a layer of sand of substantially uniform thickness; curing at least a portion of the sand layer; and determining a cured portion of the sand layer based on a desired mold shape A method of forming a sand mold for rapid casting comprising the steps of machining and repeating the steps of forming the layer, curing and machining until the sand mold is complete. Another aspect includes a machine for forming a sand mold having a building envelope defined by side walls, a movable building platform, and at least one movable tool assembly, the movable tool assembly comprising a sand dispenser, a sand leveling machine. Having a single or a plurality of tools selected from the group consisting of a device, a curing device, and a machining device.
