During the awards dinner of the 6th edition of the Additive World Conference, Chairman of the Jury, Ultimaker co-founder, Erik de Bruijn, announced Aidro Hydraulics and Fraunhofer Institute winners of the Additive World Design for Additive Manufacturing Challenge. All six finalists, three in the student category and three professionals, pitched their designs in front of the 5 member jury. After deliberation they made a well-advised selection in both categories. The awards, a set of gears and a hydraulic manifold, were for redesigns of very common industrial parts where the impact of the design for additive manufacturing would be substantial.
In the student category the first prize went to Yogeshkumar Katrodiya, an Indian student currently finalizing his Master-study at the Fraunhofer Institute in Augsburg, Germany. Yogeshkumar designed a fully integrated shaft and gear with internal channels transporting lubricant to the gears for cooling. The helix shaped cooling channels were applied to increase the cooling capacity and they demonstrated the unique design freedom of metal additive manufacturing. With help of part consolidation and topology optimization, Yogesh obtained a weight reduction of 50%. Decisive for the jury was the generic applicability and the large number of potential applications for his design.
The winner of the professional category was Aidro Hydraulics of Italy, headed by Alberto Tacconelli. Aidro CEO Valeria Tirelli presented their compact redesign of a generic hydraulic manifold for a street cleaning vehicle, designed by Gaetano Corrado. The redesign consolidated two parts, is smaller than its predecessor, and has an optimized flow because of improved, curved channels. Moreover, the problem of leakage, caused by auxiliary plug failure, is eliminated and the weight is reduced by an impressive 70%. Aidro Hydraulics won the jury over with the massive applicability and commercial viability of their design. All finalists received a free 1 year licence of Altair Inspire and Autodesk Netfabb software. Yogeshkumar Katrodiya, as student winner, took home an Ultimaker 2+ printer while the team of Aidro Hydraulics won an Ultimaker 3.
