A Review on Rapid Prototype Technology

Rapid Prototyping (RP) techniques are methods that allow designers to produce physical prototypes quickly. It consists of various manufacturing processes by which a solid physical model of part is made directly from 3D CAD model data without any special tooling. The first commercial RP process was brought on the market in 1987. Nowadays, more than 30 different processes with high accuracy and a large choice of materials exist. A CAD technique to allow 'œAutomatic' creation of a physical model or prototype from a 3-D model leads to concurrent engineering. In the RP process the 3D CAD data is sliced into thin cross sectional planes by a computer. The cross sections are sent from the computer to the RP machine which builds the part layer by layer. It is bonded to a starting base and additional layers are bonded on the top of the first shaped according to their respective cross sectional planes. The advantages of RP is Possibility of manufacturing parts which are impossible to be produced conventionally in a single process, it can be fully atomized also reduce lead time, and no supervision is required. Also it has High Resolution and No geometric limitations. This paper provides an overview of RP technology in brief and emphasizes on their ability to shorten the product design and development process. Classification of RP processes and details of few important processes is given. The description of various stages of data preparation and model building has been presented. An attempt has been made to include some important factors to be considered before starting part deposition for proper utilization of potentials of RP processes.
