to feed them with information and tell them what to do. They cannot come up with any new information, but they can save much time and work. For example, all the information and the office files (文件) can be stored in a computer’s “memory”.Imagine having a printer that could make anything. Need new shoes? Just choose a style and size and then print some.
No machine can make all of these things, but 3-D printers are getting very close. Traditional printers put ink on paper. But 3-D printers work with plastic, metal or other materials, including food. Invented in the mid-1980s, 3-D printing is a new technology (技术).
In the past, 3-D printers were so expensive that only large companies could afford them. In the last one or two years, their cost has dropped greatly. Today, you can buy a 3-D printer for as little as $300. The technology offers the potential (可能性) to print anything at home. When you want something, you needn’t buy it in a store or order it from a factory.
3-D printing can be fun too. For the Valentine’s Day (情人节) last year, a Japanese company used a 3-D printer to make chocolate copies of people’s faces. At the Fashion Week in Paris, 3-D printing made an appearance too. The clothes were made for show, not for everyday use. But that could soon change. A designer says, “It will only be a matter of time before we see the clothing we wear today produced with this technology.”
