    摘要: The present invention relates to a method for producing three-dimensional plaster objects via thin layer deposition. The inventive method comprises steps of depositing a layer of a calcium sulfate hemihydrate slurry onto the surface of a support in a predetermined pattern and activating the slurry with an activating agent so as to accelerate the setting reaction of calcium sulfate hemihydrate and water to form set calcium sulfate dihydrate. The depositing and activating steps can be repeated as necessary until the desired three-dimensional plaster object is formed.

    摘要: A slurry spray machine for spraying a settable slurry includes a main passageway configured for receiving a supply of pressurized slurry and having a supply end and an outlet end opposite the supply end. A first compressed gas inlet is disposed intermediate the supply and outlet ends and in fluid communication with the passageway for introducing a first supply of pressurized gas into the slurry, and a second pressurized gas inlet is disposed closer to the outlet end than the first inlet and in fluid communication with the passageway for introducing a second supply of pressurized gas into the slurry. A pressurized supply of adjuvant is provided in fluid communication with the second pressurized gas inlet for providing a blended gas to the second gas inlet. At least one valve is provided for controlling the flow of slurry through the passageway and the flow of the first and second gases into the passageway. Prior to the pressurized ejection of the slurry from the outlet end, the first gas is injected into the slurry, and the blended gas is mixed with the slurry and the first pressurized gas between the first gas inlet and the outlet end.
