At Alexandria Country Day School in Virginia, a group of sixth-graders had a special project (项目). They used 3D printers to create(创造) mini 3D-printed model villages for people without places to live in. The students got the idea from a company (公司) called Icon. With 3D printers, Icon makes cheap homes for everyone. And building these homes just takes a few days.
Allison McDonald is the science teacher and the director (负责人) of the sixth-grade project. She said, “Through the project, the students not only learned about the high technology (技术) and teamwork, but they also learned to know the true needs of homeless people.” While creating their mini 3D buildings, the students studied how to better use the technology in everyday life. They said getting everything ready before printing was hard. Putting a lot of ideas into their neighborhood, they made houses, stores, and schools. Also, they made churches, health centers, theaters and even bus stops to make people get a sense of belonging (归属感).
Amber Fogarty is the director of Mobile Loaves & Fishes and gives homes for people in need for free. After learning about the students’ project, Amber said, “Both the project and the students are excellent! How can you use your brains and hearts to solve problems? I don’t know what the future will be like with 3D printing. But everything is possible. It is a journey of discovery.”
