More than 60,000 people attended the Orange and White Game on Saturday, April 25, at Neyland Stadium.

Some of those visitors also checked out the Shelby Cobra 3D-printed at Oak Ridge National Laboratory, which was in the spotlight when President Barack Obama’s visited East Tennessee in January.

The Shelby Cobra went from concept to reality in only six weeks, with barely twenty-four hours of print time needed, a marked improvement made possible by the recent advances in large-scale 3D printing.

UT engineering students Alex Roschli and Andrew Messing helped with the printing itself through their internships at DOE’s Manufacturing Demonstration Facility located at ORNL, while mechanical engineering professor Butch Irick oversaw the UT team and helped with the development of the car’s powertrain.

The car’s eye-catching style captured the attention of children and adults alike. Alaina Duty, left, Katie Evans, right, and Caleb Duty, front, check out the car. Alaina and Caleb’s father is ORNL researcher, Chad Duty.

The 3D-printed Shelby Cobra was printed over the course of 24 hours at the Department of Energy’s Manufacturing Demonstration Facility at ORNL using the BAAM (Big Area Additive Manufacturing) machine. ORNL and Cincinnati Incorporated partnered to create the BAAM machine, which increases the speed of production up to 1,000 times.
