I had one teacher who was interested right away. A sixth grade social studies teacher had been going through our technology professional development program, Teacher Leadership Program, and was looking for a project he could dig into. Together we developed an idea to have his students design a coin about one of the first five presidents (a topic directly from our state standards). Each class would vote on the best design and then we would print the best ones.
There was a serious buzz in the room when I brought the 3D printer in. We have a Makerbot Replicator Mini which is compact and light-weight, so I carried it into the room myself. Students were full of comments and questions:
- "It's smaller than I thought it be."
- "How much did it cost?"
- "How long does it take to print?"
- "I want one!"

Designing in 3D is definitely easier for some students than others. Some got frustrated quickly while others drew complicated objects while I was still getting some students logged in. Showing students how to return to a home view or rotate objects were two key techniques.
What I loved about this lesson was that students got more creative due to some of the limits of the program. They drew images using small blocks (like one might in Minecraft). They got more symbolic than they might have been given other projects where they could copy and paste images or long passages of text. I also loved how they inspired each other. One students would figure out how to draw, say, the Washington Monument, and suddenly you'd see others working on a drawing of the Capitol. Our English Language Learners did fabulously with this lesson. Since most of the modeling is visual, they had no problem creating great images for their coins.
I also loved all the natural curiosity the 3D printer brought out. Students started showing up before school and during lunch to watch it print or to ask questions about how it worked. Some students that aren't your typical high achieving or tech-geeky students were the best at finding creative ways to make their 3D model or to help out with the printing process. My heart is always lifted by lessons that draw new students into the learning process.
