Question

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.”
