A

Several years ago, Kevin Stephan, then aged 11, was playing baseball when a player accidentally hit him with a bat.

Kevin fell down and his heart stopped. Penny Brown, the mother of another player, was watching the game. Penny usually worked in the evenings as a nurse, but luckily that evening she wasn't working. Penny ran to help Kevin and saved his life.

Nearly seven years later, Kevin was washing up in the kitchen of the Hillview Restaurant in Buffalo, New York State. Normally, 18-year-old Kevin had school in the afternoon, but that week there were exams and he didn't have any class. At about 2 p.m., Penny Brown was having lunch with her family in the restaurant. She was eating when some food got stuck in her throat. She was very frightened because she couldn't breathe.

Kevin was a volunteer firefighter in his free time and he ran to help. A waitress tried to help her, but the food was still stuck in Penny's throat. Kevin pulled his hands quickly into her mouth and saved Penny's life. He didn't know it was Penny, but his mother, Lorraine Stephan, was also having lunch in the restaurant. She realized that Penny was the woman who saved Kevin's life, seven years before, at the baseball game. Both Penny and Kevin were completely amazed by the coincidence(巧合)!

Amos Dudley, a 24-year-old boy who studies digital design at New Jersey University of Technology, felt ashamed about his teeth. But being a student, Dudley didn't have the money to get braces(牙箍). So, he decided to

3-D print his own and marked down the DIY project in a recent blog post. His braces totaled less than $60, and after wearing them for 16 weeks, his teeth are also getting straighter.

Months ago, he mentioned on his blog that he avoided smiling for a while because he was unhappy with his teeth.

However, clear braces can get pricey, costing up to $8,000. But after studying some images of these expensive clear braces, something comes up on him - they looked like that one which can come from a 3-D printer.

So he decided to hit up his school's 3-D printing equipment and scanned and printed models of his teeth. He

then made non-harmful plastic molds(模子) around them to make 12 sets of braces.

Dudley, who does not recommend attempting any of this at home said that he didn't ask a dentist for his project. But the student did get information from journal articles and textbooks. And though this was a perfectly

friendly choice to buy braces. He didn't accept the project just to save money - he was also up for the challenge. "When I realized that I could do something that was a little bit special, while proving my skills as a designer and a maker, and fixing something that was making me self-conscious for actually free, I felt it was more than worth the risk," he said.
