【題目】 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 (打印機)!

The possibilities of 3-D printing seem endless. All the user has to do is to design (設(shè)計) 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 “print”, the 3-D printer spreads the material layer () by layer and like magic the object is produced.

The first 3-D printer was invented in 1986 by 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 (家具) made from old fridges. And doctors have used 3-D printing to print human body parts! A newspaper 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 printinggets into the wrong hands, it can be dangerous. In 2011 a group of four men in the US used 3-D printing to produce ATM skimmers (提款機盜刷器). 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 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!
