【正文】 en seeing your face made out of chocolate? Done. All you need is a 3D printer. The possibilities of 3D printing seem endless. All the user has to do is to design an object on the puter and choose a material to print in. The printers print in hundreds of different materials including glass, sugar and even skin! When the user presses print, the 3D printer spreads the materials layer by layer and like magic the object is produced. The first 3D printer was invented in 1986 by American, Charles Hull. But 3D printing has only bee cheap enough recently for most people to use. Designers now use 3D printing to create unusual things. The Dutch artist Dirk Vander Kooj prints furniture made from old fridges. And doctors have used 3D printing to print human body parts! The Telegraph reported in February that scientists from Cornell Medical College even printed a manmade ear. But like a lot of new technologies, if 3D printing gets into the wrong hands, it can be dangerous. In 2011 a group of four men in the US used 3D printing to produce ATM skimmers. These were placed on an ATM and stole over $400,000 from users of the ATM. It is terrible to think that criminals like them might one day use a 3D printer to print a gun. But for better or for worse, 3D printing has been put into use. In a few years, you39。ll probably be wondering how you could ever live without your 3D printer!（1）________ invented the first3D printer.

It is a project of the British artist, Luck Jerram. He wants to help people in the city know each other better. He thinks that so many people are sitting in front of puters and busy with their work all hours, and they almost have no chan
