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．Bryan Jaycox requires $ 15 an hour to print an object．He also charges a fee depending on the size of the object and up to $ 50 an hour for design and labor services．

The Jaycoxs also offer 3D printing classes for anyone who is interested．One of the students in a recent class was Ki Chong Tran．He plans to open a 3D printing business in Cambodia．"The demand has been amazing．It's been much more than I would have imagined," said Ki Chong Tran．

"I think 3D printing is going to be huge． It's going to make a huge impact on society as a whole," he added．

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

more consumer friendly．

But Ki Chong Tran says even current technology can make a difference in a developing country like Cambodia．"With 3D printing you can give them tools, and you put it in their hands so they are responsible more for their own development．

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," said Ki Chong Tran．

He says it's not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality．

positive through the cold season could be your best against getting ill, new study findings suggest.

In an experiment that healthy volunteers to a cold or flu virus, researchers found that people with a sunny characteristic were less likely to ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a “positive emotional style” can help the common cold and other illnesses.

Researchers believe the reasons may be both objective as in happiness increasing immune(免疫的) function and subjective as in happy people being less by a scratchy throat or runny nose. “People with a positive emotional style may have different immune to the virus,” explained the lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. “And when they do get a cold, they may their illness as being less severe.”

Cohen and his colleagues had found in a study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional tendency itself had the effect.

For the new study, the researchers had 193 healthy adults with complete standard measures of personality tendency, health-consciousness and emotional “style”. Those who be happy, energetic and easy-going were judged as having a positive emotional style, those who were often unhappy, tense and unfriendly had a negative style. The researchers gave them drops through their noses either a cold virus or a particular flu virus. Over the next six days, the reported on any aches, pains, sneezing they had, while the researchers collected data, like daily mucus(黏液) production. Cohen and his colleagues found that based on objective measures of nasal woes(鼻部的不适), happy people were less likely to develop a cold.
