Internal Strut Frame
This design was a favorite among Local Motors members who voted on the over 200 designs submitted for consideration. The Internal Strut Frame design uses vertical struts to support the upper surfaces, saving weight and making a sturdy frame/ body.
This design also employs vertical structures to support external surfaces, which acknowledges the inability of 3D printing processes to bridge horizontal gaps. AMT president Douglas K. Woods described this multi-layer design as “very futuristic … (it) design really has the ‘wow’ factor, like something Batman or the Green Hornet would drive.”
Creative structural supports, e.g., a center spine, and a clean passenger compartment are defining elements of this concept. Judge Paul R. Warndorf, AMT vice president, noted, "By incorporating simplicity and innovation via smart design and smart deployment of vehicle features, the 3DPCX brings the openness of the road inside the vehicle."
The LM Supernova incorporates interior design elements that are innovative and well considered, and still highly functional and lightweight. It demonstrates a good combination of sound design and engineering. According to Woods, “The Supernova looks tough and fast, like a Formula 1 racecar.”
The Mirage took an innovation award for incorporating layers to create 3D Printed ‘crumple zones’, which is novel and innovative. Taking into account how the technology could be used, the Mirage concept “is a great looking car, offering some solid suggestions for what can be achieved with additive manufacturing,” according to Rick Neff, manager, Market Development for Cincinnati Incorporated.
“A tribute to the minimalist in all of us, the e-Spider merges the efficiency of a smart car with the effectiveness of a desert dune buggy,” offered AMT’s Warndorf. The e-Spider’s roof design and windshield connections, as well as the incorporation of shielding accessories to allow for use in severe weather, showed a great combination of innovation and practicality.
Strati… The Winner
“Michele’s design offers an excellent balance between innovation, complexity and practicality,” Lonnie Love, group leader for Robotics and Manufacturing Systems Research at Oak Ridge National Laboratory, and judge for the 3D Printed Car Challenge. “It has good 3D lines, and the retractable roof is really cool.”
Michele Anoé, the designer of the Strati, will receive a $5,000 cash award for his submission and will be invited to see the concept manufactured at IMTS 2014.
