What would it be like if you could only use one hand? Every year, 1,500 babies are born in the US without arms. Many more children lose hands in accidents.
Some of these children can use man-made arms or hands. These are called prosthetics (义肢). They cost thousands of dollars. As kids grow, they need new, bigger ones. Over time, the cost adds up. Many families cannot afford them. This is a problem.
▲ Some of the volunteers are students. At Alexandria Country Day School (ACDS) in Virginia, a group of sixth-graders work in teams, printing prosthetics in their science class. They are using 3D printers to make prosthetics. These printers are not common printers. They print with plastic. In 90 minutes, the class can finish making about nine prosthetics.
Taylor Grace Peterson, a student from ACDS, seemed amazed by the 3D printed hand. She said it is “pretty cool” to be able to make a hand for a kid in need.
The students work with a non-profit group called e-NABLE. It has 16 designs for 3D printed hands. The prosthetic hands are made from everyday materials. A hand can be made for less than $50, as long as you have a 3D printer.Then the hands go to children in need all over the world. A 10-year-old boy in New Mexico first received the hand they made. He was born without the left hand. The boy is a huge fan of Denver Broncos (the name of an American football team in America), so the students made his prosthetic hand with the team's colours: orange and blue.Using a 3D printer is a very cheap way to make prosthetics. Lieberman, the students' science teacher, said there is also one big advantage. “If the hand we made for a child is the wrong size, we can adjust (调整) it or send him or her another one,” Lieberman said.1. 语言能力
