this is the Technology Report.Imagine having an idea,drawing it on paper,bringing it to a storeand seeing it turned into a physical object.This is now possible with the help of 3D printers.Such machines were once used justby universities and big companies,but now, stores with 3D printing servicesare appearing around the United States.Bryan Jaycox and his wife openedThe 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 servicesfor anyone who is interested."I think 3D printing is going to be huge.It's going to make a huge impact on society as a whole."One of the students in a recent class was KiChong Tran.He plans to open a 3D print business in Cambodia.3D printing services are becoming availablefor American consumers.The UPS Store is a nationwide retailerthat provides shipping, copying and other services.The UPS Store recently put 3D printersin 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.For $11, Jonathan Netter used a 3D printer to producetwo small plastic parts as part of a knuckle for a hand.He works for a medical device company,the company is testing finger prosthetics.He says the same-day or next-day printing serviceswill speed up testing of partsand get the devices to patients faster.An office supply company, Staples is selling 3D printerson its website for as low as about $1,300.A cartridge of color plastic costs $50.As with any technology-- experts expect the printing speed and price to improve.Bryan Jaycox requires $15 an hour to print an object,he also charges a fee depending on the size of the objectand up to $50 an hour for design and labor services.At The UPS Store, the cost of the objectdepends on the amount of materials used.The store charges up to $95 an hourto design the object with computer softwarethat creates a digital file to guide the printer.Mr Jaycox predicts that within five years,3D printing technology could become more consumer friendly.But KiChong Tran says even current technologycan make a difference in a developing country like Cambodia."With 3D printing you can give them tools,you put it in their handsso they are responsible more for their own developmentand they learn skills beyond just learning Englishand becoming a tour guide or something like thator working at a bank you can actually create thingsthat give value to the world."He says it's not just Cambodiabut anywhere where there is a 3D printer,it can turn a good idea -- into reality.And that's the Technology Report from VOA Learning English.更多听力请访问51voa.com
