Rapid casting
Rapid casting is an integration of conventional casting with rapid prototyping/3D printing. In this technique disposable pattern used for forming mold are created with 3d printing techniques like fused deposition, stereo lithography or any other 3d printing technique.Procedure
- A disposable pattern is made with RP
- The pattern if made of wax, undergoes wax infiltrations and other procedures to increase its strength and dewaxing properties.
- A mold is made with the printed pattern.
- Evacuation of the pattern from the mold followed by regular casting procedure.
Advantages
- Easier to make pattern.
- Reduced time of manufacturing.
- Possibility to make the pattern lighter by removing unwanted material and stiffer by adding rib features.
