How we outperformed the winner by 49%
General Electric launched an additive manufacturing design challenge on GrabCAD to minimize the mass of a titanium jet engine lifting bracket. The competition generated over 700 entries globally. The contest was closed on Nov. 2013 but has remained as a global benchmark for the lightweighting of aircraft components. The original bracket GE to redesign weighed 2,033 grams. The winner was able to slash its weight by nearly 84% to just 327 grams.
We beat the winner by more than 10% in weight. And considering the design time and removal of all support structures, we would have beat him by 49% in cost.
