Rapid prototyping is a method to quickly fabricate an almost identical physical model from a three-dimensional computer aid design (CAD) data. The principle of rapid prototyping relies on building an object from a series of stacked cross-sections. The RP software creates each cross-section laying down successive layers of liquid or other type of powdered material that will fuse together and solidify to create the final physical shape.
These models help to reduce the development time and cost by allowing corrections to be made early in the design process. Rapid prototyping saves time and money and allow to enhance the quality of the products.
