A 3D printer is a type of rapid prototyping device. It develops 3-dimensional model that closely emulate the appearance, feel and functionality of prototypes layer by layer from StereoLithography (STL) information. Items are carefully built up inside the printer as thin layers, one on the other to develop a working design. Although it has poor resolution compared with standard fast prototyping machines, nevertheless the distinction is not that big and it is much quicker, more economical and simple to utilize. This technology is frequently utilized in aerospace, architecture, automobile, shoes, commercial design, precious jewelry, oral and medical markets.
