See a cellphone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting “print” on your computer. You might find it hard to believe that you could actually “print” an object like you would draw a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3D printer uses are mainly plastic, resin(树脂) and certain metals. The thinner each layer is—from a millimetre to less than the width of a hair—the smoother and finer the object will be. This may sound like a completely new technology, but the truth is that 3D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3D printing industry—printers became much cheaper. For example, 10 years ago a desktop 3D printer might have cost ￡20,000, while now they cost only about ￡1,000, according to the BBC. Taken out of the factory and introduced to more diverse and common uses, 3D printing can create just about anything you can think of—flutes, bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3D printing becomes more common, it may bring about certain problems—such as piracy. “Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3D printer, who will visit a retail store again？” an expert in 3D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3D printer to print out a fully functioning gun?

Papa, as a son of a dirt-poor farmer, left school early and went to work in a factory, for education was for the rich then. So, the world became his school. With great interest, he read everything he could lay his hands on, listened to the town elders and learned about the world beyond his tiny hometown. "There's so much to learn," he'd say. "Though we're born stupid, only the stupid remain that way." He was determined that none of his children would be denied (拒绝) an education.
Thus, Papa insisted that we learn at least one new thing each day. Though, as children, we thought this was crazy, it would never have occurred to us to deny Papa a request. And dinner time seemed perfect for sharing what we had learned. We would talk about the news of the day; no matter how insignificant, it was never taken lightly. Papa would listen carefully and was ready with some comment, always to the point.
Then came the moment—the time to share the day's new learning.
Papa, at the head of the table, would push back his chair and pour a glass of red wine, ready to listen.
"Felice," he'd say, "tell me what you learned today."
"I learned that the population of Nepal is .... "
Silence.
Papa was thinking about what was said, as if the salvation（拯救）of the world would depend upon it. "The population of Nepal. Hmm. Well... " he'd say. "Get the map; let's see where Nepal is. " And the whole family went on a search for Nepal.
This same experience was repeated until each family member had a turn. Dinner ended only after we had a clear understanding of at least half a dozen such facts.
As children, we thought very little about these educational wonders. Our family, however, was growing together, sharing experiences and participating in one another's education. And by looking at us, listening to us, respecting our input, affirming (肯定) our value, giving us a sense of dignity, Papa was unquestionably our most influential teacher.
Later during my training as a future teacher, I studied with some of the most famous educators. They were imparting what Papa had known all along—the value of continual learning. His technique has served me well all my life. Not a single day has been wasted, though I can never tell when knowing the population of Nepal might prove useful.
