Rapid Prototyping

The word rapid prototype contains two words- rapid and prototype. The word rapid represents fast, and prototype represents a real, dimensionally accurate, and working assembly of a new or existing product.Rapid prototyping is described as a layer-by-layer manufacturing process in which different machine components like computer control, optical sensor, photosensitive sensor, deposition material, and others are used to develop an accurate dimensional physical working model.In other words, rapid prototyping is a layered manufacturing process of a product using a 3-dimensional (3D) computer-aided design model.
