In the past you could draw anything you wanted on a computer screen and then printed it out on a piece of paper—a flat piece of paper. But imagine being able to print something that is three-dimensional— 3D. Would you like to design an object, such as a cup or a toy, and then “print” it out? Well, there is the technology to help you do this—to produce even a whole house!

3D printers might be the size of a suitcase, or even a small room, depending on the object they are made to produce. You make a 3D design on your computer and send it to the printer. Inside the machine, the object you have designed is made as one object.

So how is this being used? In medicine, 3D printing is often used to make heath. The dential takes a 3D image, something like a photo of the real tooth and a new one is printed in that exact shape. Then you might also want to print a mobile phone cover or a special pair of shoes.

Scientists are taking this even further. They have made a bicycle that just needs a chain and two lyres (輪胎). Car pans (殼) have been made for a while and now they are even making a body of a whole car!

But imagine how printing a whole house might help people build houses. A Chinese company has made houses using a giant 3D printer. They use a mixture that includes concrete (混凝土) and recycled building waste. This is a good thing as it helps the environment. They believe that their method of printing houses is cheaper, faster, less dusty and less noisy than the ordinary(普通的) way that houses are built.

It seems that 3D printing technology will change our world, and China is leading the way.

1.The size of a 3D printer might be ______ according to the object they design.

A.changeable B.always small C.seldom big D.the same

2.In medicine, 3D printing is often used to print ______ in the exact shapes.

A.dentists B.teeth C.photos D.mobile phone covers

3.Scientists are taking this even further. Here “this” probably means ______.

A.a pair of shoes B.a whole car C.a new bicycle D.the printing

4.The passage is mainly about ______.

A.the introduction to 3D technology B.the advantages of 3D technology

C.the history of 3D technology D.the influence of 3D technology
