Nottingham PhD student wins Additive World Design Challenge Award for the second year running

Cassidy Silbernagel, a second year PhD research student in Mechanical Engineering has won the Additive World Design Challenge Award for the second year running.

Cassidy emerged as the winner in the students’ category after facing off stiff competition from 76 contestants, both professionals and students.

His winning entry was based on a redesigned carburetor which included integrated moving parts, floats, lightweight internal lattice structures and an optimised design to reduce the number of support structures.

The lattice structure was generated using software based on methods developed at Nottingham’s Centre for Additive Manufacturing. A free copy of the software is available for evaluation from the University’s spin-out company, Added Scientific Ltd.

The judges lauded Cassidy’s efforts and said his design showed a skilful combination of the unique characteristics of additive manufacturing. 

When asked about his motivation behind the design, Cassidy said, “I wanted to show that you can take any design and completely reimagine it. I chose the carburetor because it’s quite an old design and there’s room for improvement.”

His winning design shows that the carburetor can be made lighter and more efficient. General Electric for instance, uses additive manufacturing for parts in planes.

The winners in each category will have their designs 3D printed in metal. In addition, Cassidy also received an Ultimaker 2+ printer and an assortment of prizes from Autodesk, as well as an invitation to give a presentation during the annual Masterclass: Design for Additive Manufacturing. The event, which will be hosted by Additive Industries, will take place during Dutch Design Week in October.

Additive Manufacturing and 3D Printing (AM and 3DP) encompass technologies which fabricate components, usually layer by layer, using digital data. These technologies enable the creation of very complex shapes which is simply not possible with other conventional manufacturing methods. The use of digital design data is fundamental to this approach and research into design for Additive Manufacturing is a central theme of the research being conducted here.
