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