Direct Shell Production Casting (Ceramic molds rather than 3D models are made by DSPC in a layering process similar to other RP methods. Ceramic powder is spread by roller over the surface of a movable piston that is recessed to the depth of a single layer. Then a binder is sprayed on the ceramic powder under computer control. The next layer is bonded to the first by the binder. When all of the layers are complete, the bonded ceramic shell is removed and fired to form a durable mold suitable for use in metal casting. The mold can be used to cast a prototype. The DSPC process is considered to be an RP method because it can make molds faster and cheaper than conventional methods.  researchgate.net silver_glepha) |
