Post-processing in rapid prototyping refers to the additional steps or treatments applied to a prototype after it has been built using rapid prototyping techniques like 3D printing. These steps are essential for refining the prototype's appearance, improving its mechanical properties, or achieving specific surface finishes. Painting or coating the prototype can enhance its appearance and provide additional protection. Various techniques such as spray painting, brush painting, or dip coating can be employed depending on the desired finish.
