Be Fast! Computer-Aided Drafting Program Hosts 3D Printed Car Race

Excitement was in the air as the third Annual Western Dakota Tech Computer-Aided Drafting (CAD) 3D Printed Car Race took place in the Event Center on Dec. 12. The CAD students created amazing vehicles they raced on a new 80-foot long track which proved to be a true test of endurance and top end speed.

Alex Weidenbach, second year student from Rapid City, designed the winning race car.

CAD students have been working on making 3D cars throughout the course of the semester. The cars are powered by an electric motor and a 9V battery. The frame, body, and gears are designed in 3D CAD by each student and then 3D printed. This project allows students to apply what they have learned with parametric 3D modeling of assemblies, gear and belt drive systems, and tolerances required to achieve different types of assembly fits. The winner gets lots of “street cred” and an Autodesk laptop backpack.
