Computer-Aided Manufacturing<\/h3>\r\nFor many companies, the next step is to link CAD to the manufacturing process.

Flexible Manufacturing Systems<\/h3>\r\nFinally, a CIM system is a common element in flexible manufacturing systems (FMS)<\/span><\/span>, in which computer-controlled equipment can easily be adapted to produce a variety of goods. An FMS has immense advantages over traditional production lines in which machines are set up to produce only one type of good. When the firm needs to switch a production line to manufacture a new product, substantial time and money are often spent in modifying equipment. An FMS makes it possible to change equipment setups merely by reprogramming computer-controlled machines. Such flexibility is particularly valuable to companies that produce customized products.\r\n
3D Printing<\/h3>\r\n3D printing\u00a0(or\u00a0additive manufacturing, AM) is any of various processes used to make a\u00a0three-dimensional\u00a0object.\u00a0In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control.\u00a0These objects can be of almost any shape or geometry, and are produced from a\u00a03D model\u00a0or other electronic data source. A 3D printer is a type of\u00a0industrial robot. Several different 3D printing processes have been invented since the late 1970s. The printers were originally large, expensive, and highly limited in what they could produce.\r\n\r\nhttps:\/\/youtu.be\/_n9vPNAzKVY\r\n\r\nA large number of additive processes are now available. The main differences between processes are in the way layers are deposited to create parts and in the materials that are used. Some methods melt or soften material to produce the layers, while others cure liquid materials using different sophisticated technologies. With\u00a0laminated object manufacturing\u00a0(LOM), thin layers are cut to shape and joined together (e.g. paper, polymer, metal). Each method has its own advantages and drawbacks, which is why some companies consequently offer a choice between the material used to build the object.\u00a0Other companies sometimes use standard, off-the-shelf business paper as the build material to produce a durable prototype. The main considerations in choosing a machine are generally speed, cost of the 3D printer, cost of the printed prototype, cost and choice of materials, and color capabilities.\u00a0Printers that work directly with metals are expensive. In some cases, however, less expensive printers can be used to make a mould, which is then used to make metal parts.\r\n
