B
The latest technology inventions in 3D printing are rapidly changing how things are being made.
At the International Manufacturing (制造業(yè)) Technology Show in Chicago,a little-known car maker became popular by manufacturing a car at the show.
It was a fully functional car that was 3D printed in 44 hours and assembled(裝配) in two days. The car is called a “Strati”,Italian for layers,so named by its designer Michele Anoe because the entire structure of the car is made from different layers of materials.
The average car has more than 20,000 parts but this latest technology reduces the number of parts to 40. uThe goal here is to get the number of parts down and to drop the tooling costs to almost zero,” said John B. Rogers Jr.? chief manager of Local Motors. “Cars are ridiculously complex,” he added,referring to the thousands of bits and pieces that are sourced,assembled and connected to make a vehicle.
This technology can use a variety of materials to manufacture anything in complicated detail. Imagine if you could order a new car online according to your needs and pick it up of have it delivered to you the next day at a small part of the cost of buying one from a shop? What if you could make small parts at a lower cost rather than buying them from a parts supplier? What a great change would that be for the industry? It's already happening.
One of the challenges with collecting antique (古老的) cars is replacing parts. You can't buy them because they're not in use and it's difficult to find the parts that fit. But now people can use 3D printing technology to make parts for their cars.
John B. Rogers Jr. believes that in the near future a car will be made in just 60 minutes. The company is already organizing a worldwide network of “Microfactories” where you can order and pick up your personalized car.

Last Sunday,I went to Beijing Olympic Forest Park with my friends Chris. As soon as we got there,we were very attracted by the breathtaking scenery that we couldn't help to taking many photos. As we walked on,we noticed a kite hang up on a branch,but its owner,a little boy,was too short to get it down. The boy looked worrying and we decided to help him. Unluckily,the kite was also beyond my reach. Then we looked around and found a stick,with what we got the kite down. We gave kite back to the boy. He was very delighted and thanked us for what we do. We also felt very happy and it made our outing more enjoyably.
