Rapid prototyping is the method of constructing physical objects using solid freeform fabrication. The use of rapid prototyping techniques had its start during the 1980’s where it was used to build product models. Its current applications have been put into use in a wider range of objectives.
The technique can even be used in order to manufacture quality useable parts in small numbers. Rapid prototyping has even found some applications in the art scene where sculptors use the technology to create intricate shapes that become art pieces.

This technology is also used by the sculptors in order to achieve complicated shapes for display in any exhibition of fine arts. Rapid prototype creates 3D models with the help of virtual designs from animation modeling software or computer-aided design, which helps in transforming the design into thin layers, virtual and horizontal cross sections until the entire model is complete and all these can be done with the help of additive manufacturing technology present in rapid prototyping. With the use of this particular technology the virtual image can be easily transformed into the physical model.
• The additive manufacturing technology helps the machine to read data from computer aided design and builds the model with the help of layers of liquid, powder and sheet material. Various cross sections are used while building up the model. The layers are combined with the virtual cross section automatically to get the final shape.

Rapid prototyping is a process of software development wherein physical objects are automatically constructed by means of SFF or solid freeform fabrication. In the process of rapid prototyping, a prototype or working model can be constructed quickly, and tested for its functionality, performance and output. The new features or ideas can be illustrated well in the prototype and early user feedback can be gathered with regards to the product. There are numerous advantages of rapid prototyping.
Benefits of Rapid Prototyping: Significant advantages of rapid prototyping include reduction of project cost and risk. Generally, one or more prototypes are developed in the process of software development in a series of incremental and iterative steps. Every prototype that is manufactured is based on the previous designs’ performance and it is a corrective process through which the past design defects or problems are corrected. The product is readied for production when the prototype is refined as per requirements and meets all the design goals like manufacturability, robustness and functionality.
