Rapid prototyping is a way to quickly fabricate and visualize a solid model of a part or assembly using 3D CAD data. In other words, it is a fast and more cost-effective method for creating prototypes for product development.
It helps for a multitude of uses like functional testing, tooling, moulds, visualization and as a proof of concept. Deeper uses of Rapid Prototyping include decreased development time, reduce costly mistakes, give an effective communication to the end user and allow multiple variants if the product.
