“With the generous help of Richard Gregory from 3D Systems, the students' invention was actually made into a prototype model," said Mrs. Elizabeth Lambert, 2nd grade teacher.

3D Systems used the V-Flash® Desktop Modeler to build the parts.

The students were excited and amazed to have a real model of their invention.

Mrs. Lambert said, “I never dreamed we would get this far with our invention. It's very exciting!”
