On February 13, 2017 Additive Industries announced the finalists of Additive World Design for Additive Manufacturing Challenge 2017. Finalists include last years’ winner Cassidy Silbernagel from Calgary AB, representing the University of Nottingham.
Last years’ winning design was an innovative electric motor casing to fit into an existing crankshaft case of a regular motorcycle enabling electrification. Silbernagel’s design reduces eight parts to one lightweight component and integrated room for heat transfer and well-rounded wiring tunnels.

For this years’ contest designers were asked to tailor their designs, to eliminate manufacturing difficulties, reduce the number of parts, minimize assembly or lower logistics costs, often combined. Designs were submitted from all over the world including the US, the Netherlands, Germany, UK, Spain, India, Russia and Italy representing different sectors, advanced food processing, the aeronautics industry, automotive as well as high-tech.
“After seeing last year’s winning professional design, I was inspired to create a design which also had moving parts,” said Cassidy. This years submission is a redesigned additive manufactured carburettor for an internal combustion engine, Cassidy wanted to show an assembly of moving parts without normal assembly. It is extremely lightweight from the thin walls and self-supporting lattices.
The other finalists for the student category include the team Alliance from the Alliance University (Department of Aerospace Engineering, India) who integrated three key benefits of AM in test model manufacturing for a Supersonic Wind Tunnel: no tooling is required, costs effective for complex geometries, fast turnaround from design to part. The student from the Russian Federation, Boris Sokolov, optimised the design of an industrial robot arm with topology optimization.

A graduate of Mechanical Engineering at the University of Calgary, Cassidy is in the UK currently pursuing a PhD at the University of Nottingham. He is researching the possibility of using AM in electric motors, specifically using AM to create coils/windings using a conductive metal like copper or aluminum and an insulating material like ceramic.
“I would ultimately like to bring this experience I’ve gained in AM and design for AM back to Canada so that it can become a world leader in the technology,” Cassidy offered.
Winners are to be announced on Wednesday March 15, during Additive World Awards Dinner in Eindhoven, The Netherlands.
