Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into an 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 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 influence on society as a whole.” says KiChong Tran, one of the students in a recent class. He plans to open a 3D printing business in Cambodia (柬埔寨).
3D printing services are coming into American people’s life. The UPS Store is a nationwide retailer (零售商) that provides 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. There has been a lot of interest from people. It’s been much more than I would have imagined.”
The UPS Store plans to add 3D printers in three more stores.
For $11, someone used a 3D printer to produce two small plastic parts as part of a knuckle (指节) for a hand. He works for the company which is testing finger prosthetics (假肢). He says the same–day or next-day printing services will speed up testing of parts and get them to patients faster.
Staples, an American store, is selling 3D printers on its website for as low as about $1,300. As with any technology - experts expect the printing speed to increase and the price to go down.
Bryan Jaycox requires $15 an hour to print an object. He also sets the price depending on the size of the object and up to $50 an hour for design and labor services.
Mr Jaycox thinks that within five years, 3D printing technology could become more user friendly. But KiChong Tran says even today’s technology can make a difference in a developing country like Cambodia.
“With 3D printing you can give them tools, so they are responsible more for their own development and they learn skills beyond just like learning English and becoming a tour guide or something like that. You can actually create things that give value to the world.”
He says it’s not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality.What can 3D printers do according to the passage?

I was quite close to my grandmother, Julia. We lived with her and then she lived with us. She was a very nice person, both kind and patient. She taught me to read and write when I was young and helped me to be interested in stories and poems.
In my mind, my grandmother was a great cook. She cooked more delicious food than anything you can eat in a restaurant today. She always cooked for family and friends.
My grandmother was also a hard worker both at home and at work. I can still remember the difficult time when we were very poor.
