题目内容

Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into a

physical object. This is now possible with the help of 3D printers. Such machines were once used just

by universities and big companies, but now, stores with 3D printing services are appearing around the

United States.

Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The store

is filled with tools like a laser cutter, an industrial sewing machine and 3D printers. The Jaycoxs offer

3D printing classes and services for anyone who is interested.

"I think 3D printing is going to be huge. It's going to have a huge effect on society as a whole."

One of the students in a recent class was KiChong Tran. He plans to open a 3D printing business in

Cambodia.

3D printing services are becoming available for American consumers.

The UPS Store is a nationwide retailer (零售商 ) that provides shipping, copying and other

services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke

Jones owns one of the stores in San Diego.

"The demand has been amazing. It's been much more than I would have imagined." The UPS

Store plans to add 3D printers in three more stores.

At The UPS Store, the cost of the object depends on the amount of materials used. The store

charges up to $95 an hour to design the object with computer software that creates a digital file to

guide the printer.

Mr. Jaycox predicts that within five years, 3D printing technology could become more popular.

But KiChong Tran says even current technology can make a difference in a developing country like

Cambodia.

"With 3D printing, you can give them tools; you put it in their hands so they are responsible

more for their own development and they learn skills beyond just learning English and becoming a

tour guide or something like that or working at a bank; you can actually create things that give value

to the world."

He says it's not just in Cambodia but anywhere where there is a 3D printer that it can turn a good

idea into reality.
