3D Printed CO2 Car Project
thingiverse
My Industrial Technology class includes a transportation unit, culminating in students building CO2 cars. This year, I took it up a notch: they designed their cars using Autodesk Inventor software and 3D-printed each design. It was fascinating to observe the design process, as students had to create printable, aerodynamic cars. The results were impressive; I shared the project online, hoping to inspire others. Students posted their designs' files, and I look forward to seeing remixes in future. Check out these videos of students having a blast: [YouTube link 1], [YouTube link 2], [YouTube link 3]. 3Dprint.com also featured our project; read about it here: http://3dprint.com/4230/3d-printed-co2-car-race/. Students used Autodesk Inventor and Netfabb for STL file manipulation. For guidelines, see "CO2DesignProject.pdf." I gave open specifications to encourage creativity. Grades 11 & 12 participated; skill levels ranged from beginner to intermediate. Students sketched designs on graph paper before computer design. They calculated car weight equations and determined vehicle volume. Cars were 3D printed, then raced down a fishing line-connected track using PITSCO launchers. I evaluated projects based on directions followed, originality, and adherence to specifications. Students enjoyed the project, sparking interest in my program.
