4th graders in Mr. Doty's class got an introduction to the concepts and the process of 3D printing during a study of inventions. To begin, they researched inventions of the past and predicted inventions for the future. Students found that solving a problem or filling a need is the motivation behind inventions.
They spent time designing and creating their own invention based on a need that they have observed. Then they practiced persuasive writing in order to "sell" the concept of their invention. These young inventors built with Legos and other building sets. Many discovered that specifically designed pieces are often necessary to make an invention function according to plan.
The class was then visited by Dwaine Williams, a mechanical engineer and entrepreneur, who demonstrated the use of his custom-built 3D printer. He also shared many of his recent projects, including the working parts of a life-sized robot being constructed.
Each student got to watch the 3D printer in action as it printed Boone Toreador personalized ornaments.
