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.

gollark: Technically YAML is backward-compatible with JSON through some weird hackery, if I remember right. And JSON's not whitespace-sensitive. So you could do that.

gollark: Actually, better idea: HQ9+ configuration.
