247. Sintered ceramic mold directly with the SLS
Based on Rapid Prototyping of Ceramic casting process:
1. In three-dimensional CAD modeling system to complete three-dimensional physical appearance of the casting design. STL files generated appearance.
2. On the appearance of the STL file handling, layers, plus support.
3. Rapid prototyping machines have been the appearance of stratification under the control of supporting documents to create a look of resin prototype.
4. Slurry directly hung in the prototype, the production of ceramic shell. At room temperature for about 2h, removed from the ceramic shell prototype.
5. Within the ceramic shell in the baking furnace (200 degrees) 5h removed after cooling.
6. Cast metal, are casting.
7. On the sand castings and other follow-up treatment process, the metal castings. 8) the size of casting, mechanical properties testing.
