The 3D printer is the latest invention of science. 3D printers can make daily life things very easily. They are amazing due to their ability to the production of various types of objects, via various kinds of materials and all these things via the same machine. It is able to make a replica of anything like ceramic cups, plastic toys, metal machines parts, stoneware vases, fancy chocolate cakes, or even (one day soon) human body parts. A 3D printer is a computer-aided manufacturing (CAM) device that designs 3-D objects. It receives commands from a computer as input, like a conventional printer. It produces a three-dimensional model, which is different from a conventional one. The working of a 3D printer is based on the additive manufacturing process for printing physical objects layer by layer until the model is complete.
