Three-dimensional (3D) printing is the process of making a solid object of virtually any shape from a digital model. The technology is based on an additive process whereby successive layers of material are used to craft a 3D model. It is also known as additive manufacturing. The scale of a printer is only limited by the size of the frame of the printer. The technology has developed so rapidly that home users can now print objects ranging in size from a small plastic doll to as large as a doll house. Businesses too have begun using additive technology to print objects as large as car radials. And these are made of metal. The technology has also been used to fabricate objects that consist of many small parts and components, such as guns. And now there s talk of human body parts, too. The time taken for printing an object also varies, depending on the size.  Printers can be bought for prices ranging from as low as Rs 29,995 to Rs 1.5 lakh on sites like ebay India and even more on overseas websites that offer international delivery.
