3D printer appeared in the mid-1990s, and it is actually a rapid prototyping equipment using light curing and paper lamination technologies. This technology is now applied in many fields. People use it to make food, clothes, shoes and hats, building models, cars, human bones and blood vessels.

3D Systems plans to launch a home 3D printer called Cube this year, which can print prostheses, hearing AIDS, shoes and other items. The price of this printer is 1299 USD. It is equipped with 25 templates and can surf the Internet wirelessly. Kathy Lewis, vice president of global marketing of 3D Systems, said in an interview with Microsoft-National Broadcasting Network: "With 3D printing, everything is no longer complicated. 3D printers can create almost anything. "

Researchers in some countries have consistently developed food printers. The food printer developed by Cornell University in the United States mainly consists of syringes, using special "inks" such as cheese, chocolate and cake paste. After the user presses the "print" button, the food printer prints out various ingredients "ink" in the syringe in turn according to the electronic drawings. Electronic drawings, like recipes, accurately specify the sequence of "ink ejection" of syringes and how various components are distributed and stacked.

Homaro Cantu, a famous chef at Moto Restaurant in Chicago, Illinois, said that he used to make sushi with a food printer.
