M. Arie Kurniawan from Salatiga, Indonesia, won first prize in the GE 3D Printing Design Quest.

That means Kurniawan will collect the $7,000 grand prize in the contest to redesign loading brackets found on jet engines using 3D printing.

The remaining $20,000 will be split between the other seven finalists. They are:

2. Thomas Johansson, Ph.D, Sweden - $5,000
3. Sebastien Vavassori, the United Kingdom - $3,000
4. Nic Adams, Australia - $1,000.
5. Fidel Chirtes, Romania - $1,000.
6. Mandli Peter, Hungary - $1,000.
7. Andreas Anedda, Italy - $1,000.
8. Piotr Mikulski, Poland - $1,000.

Kurniawan's bracket had the best combination of stiffness and light weight. The original bracket weighed 4.48 pounds, but Kurniawan was able to slash its weight by nearly 84 percent to just 0.72 pounds.

He says that he was inspired by the H-beam profile because it can handle both a vertical and horizontal load.

"3D printing will be available for everyone in the very near future," said Kurniawan, who runs a small engineering and design firm called DTECH-ENGINEERING with his brother. "That's why I want to be familiar with additive manufacturing as soon as possible."

Nearly 700 people from 56 countries competed in the contest.

"At GE, we know innovation can come from anywhere," GE Executive Director of Global Innovation Steve Liguori said. "This challenge tapped into the ingenuity of the GrabCAD community to unleash new solutions to tomorrow's challenges using additive manufacturing. By applying GE's scale and expertise to open innovation, we can continue to grow the ecosystem of designers, engineers, materials scientists, and other partners to redefine the industry and drive real results for our customers."

The top ten bracket designs were 3D printed at GE aviation's additive manufacturing facility in Cincinnati and subjected to rigorous load testing at GE's global research center in Niskayuna, N.Y.

Testing was performed to ensure the winning designs met the highest quality and performance criteria. Loading brackets on jet engines play a critical role: they must support the weight of the engine during handling without breaking or warping.

GE and GrabCad, working closely with the digital strategy firm Undercurrent, launched the contest last June.

"There were an extraordinary number of submissions from around the world, because engineers want the chance to design something that may make it into production and solve a real problem," said GrabCAD CEO Hardi Meybaum. "GE's Jet Engine Bracket Design Challenge exceeded expectations and shows its commitment to seeking innovation through open engineering and collaboration. It's the way of the future, and we love that it's happening on our platform."
