Student team wins 3D printing competition

The Tennessean (Knoxville, Ten., Sept. 17) – A team of engineers working to create a miniature additive manufactured excavator that could be 3-D printed on Mars unveiled the excavator at the Oak Ridge National Laboratory. The excavator driver’s cab was the result of a competition among five universities, won by a five-person engineering team from Illinois. Their prize was $2,000 and a trip to ORNL. Their elegant 3-D-printed cab looked as if it had been forged from a black iron cobweb. "We were inspired by shapes found in nature like curved and arching tree branches," team member Sharon Tsubasa says.
