My fifth grade students are learning everything they can about 3D printing...how it works, why 3D printing is important, and what is possible to 3D print. Now we begin learning how to create 3D designs using a couple of different programs. We are going to explore the Gravity Sketch app and learn Tinkercad, an easy to use CAD design tool. Below is our first look at our Ultimaker 2 in action. The kids are always amazed by the printer and seeing it work.
