Have you ever had dreams about building a robot？Or putting together a spaceship？Or even seeing your face made out of chocolate？Done．All you need is a 3﹣D printer．

The possibilities of 3﹣D printing seem endless （无穷尽的）．All the user has to do is to design an object on the computer 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 （按）﹣print，the 3﹣D printer spreads the materials layer （层） by layer and like magic the object is produced．

The first 3﹣D printer was invented in 1986by 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!
