“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.”
