||Custom Forearm Crutch Handgrip with Integrated iPod Controller and Flashlight (PDF)
Adam McLaughlin, Jordan Tye, Lisabet Sizer and Mark Damplo, University of Massachusetts Lowell
Synopsis: A custom forearm crutch handgrip with an integrated iPod controller and flashlight was designed and manufactured using direct digital manufacturing (DDM) to be included in the final assembly of a crutch. The design is marketable to anyone in need of a forearm crutch, especially those with lifelong disabilities and those injured in the military.
||Adjustable Blade Ceiling Fan (PDF)
Edward Schwartzkopf Jr., Ismail Kuru, Andrew Parcels and Paul Jansen, Southern Illinois University Edwardsville

For 2011, student designers were encouraged to use their imagination to design a product intended to be, or be part of, a system that utilizes direct digital manufacturing (DDM) in features. The product had to have the ability to be used in another assembly and fabricated mainly using DDM processes.
The overall design item had to be a device, assembly or subassembly within another product, or a mechanism. The design also had to represent a fully working prototype. Any internal electronics or mechanics were to be specified within the design. The geometry of the design also had to be defined within a three-dimensional (3D), computer-aided design (CAD) system capable of producing robust STL files.
