今天分享给大家的是关于科技类3D打印技术的相关报道，大家注意积累词汇句型观点，写作口语都可以用到！
在雅思写作或雅思口语回答中用到这个例子，一定会非常炫！美国第一辆3D打印汽车发布，非常短小好读的报道，试着自己复述一下，变成自己的例子吧！
3D-printing: American company Local Motors releases world’s first computer-printed car发布第一台电脑打印的车
Hearing aids, prosthetic limbs, even guns… 3D printers are certainly the creators of the future.
But now they are driving in a new direction.
American company Local Motors has built the world’s first 3D-printed car, made from a mix of carbon fibre and plastic.
The car’s body was created over two days, in a giant printer at a Chicago trade show.
It then took one day to refine the shape and two days to assemble the lightweight vehicle… which weighs in around 1,000 kilograms.车的制造流程，用到口语中会很棒
Local Motors engineer James Earl was part of the team which followed the design process from its beginnings in May this year.
Just four months later, he said he was excited the first, printed electric car was rolling off the production line.生产出来
“It’s not a very long time frame from conception to design to production, especially compared with traditionally-made vehicles,与传统汽车的比较” he said.
Although other car parts have been printed before, this is the first time a car chassis has been printed in one piece, using direct digital manufacturing.
Only a few parts, like the electric engine, suspension and tyres, were made using traditional methods.传统方法制造的部分
In total, the new car has only 49 parts, significantly less than a standard car, which has around 5,000.3D打印的车比传统车的优势
“The thing that this lends most to is customisation-ality, so you can get a car that really suits your needs with very little monetary input资金投入 from the design side,” Mr Earl said.
Called the ‘Strati’, the Italian word for ‘layers’, the battery-powered car can reach speeds of 65 kilometres per hour, although it is not yet allowed on actual roads.
Local Motors expects that approval will come soon.
It says the Strati will retail for around $20,000.
