2011 DDM Winners


First Place
1st Place 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.
Second Place
2nd Place Adjustable Blade Ceiling Fan (PDF)
Edward Schwartzkopf Jr., Ismail Kuru, Andrew Parcels and Paul Jansen, Southern Illinois University Edwardsville

Synopsis: This design is a customizable ceiling fan with adjustable blade angles to allow multiple flow rate settings, rather than a multiple speed motor. The design is being made with three main goals in mind: (1) adjustable blade angles, (2) simplified secondary components and (3) minimal assembly.
Third Place
3rd Place Custom PlayStation 3 Controller Utilizing Direct Digital Manufacturing (PDF)
Joshua Valley, Benjamin Zlindra-Short and Jon Salerno, University of Massachusetts Lowell

Synopsis: A customizable PlayStation 3 controller was designed for direct digital manufacturing (DDM). Using the stock electronics from a SixAxis PlayStation controller a new custom controller was reverse engineered. This design can be changed to fit whichever consumer market or customer that the controller is geared toward.

The Task
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.
