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 (that can be of wax or any other plastic used in 3d printing)
  • 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.
