Rapid Prototyping
Rapid prototyping, as the name suggests, is producing a prototype quickly and efficiently. It is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design data. Construction of the part or assembly is usually done using 3D printing or "additive layer manufacturing" technology
Advantages of rapid prototyping
Reduced design & development time
Reduced overall product development cost
Elimination or reduction of risk
Allows functionality testing
Improved and increased user involvement
Ability to evaluate human factors and ergonomics
