【正文】 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.
