Innovation

   Nowadays, as techinques are developing, many useful products are invented. One of them, a 3D printer is emerging from many different fields. This machine is invented by the Company of 3D Systems in U.S. A 3D printer is a machine that makes cubic shape of real products based on three-dimensional blueprint made by computer designing program. In the old days, there are little materials so the machine could not develop so that much. However, in recent days, as a range of  materials expands, the printer can be used many parts of industries with different ways and generalized because of many advantages.
   First, one of the advantages is that a 3D printer can save energy. Recently, many techinques are developed so that environment is destroyed. However, if you use this machine, it is possible to reduce expense of products and energy because you don't need to import or export products by downloading 3D contents from internet at home. Eventually, you can prevent pollution through reducing energy.
   Second, a 3D printer can be cooperated with many parts of industries, and the main point is own taste of consumers. For example, consumers can prescribe medicines using computer by oneself. Many people want to live more long, and healthful, and if they use this machine, they can prescribe more proper medicine so they can take a dose convinently. And also, consumers can make clothes, shoes, accessaries and etc. suited their taste. This printer can make a shape of products, so consumers can choose many designs of clothes what they want. So they can buy clothes in a short time, and more accurately.
   Like this, a 3D printer can be used on various ways on various fields. Therefore. we should develop this machine, so it will be activated many hidden industries.
