Share this

SCHAUMBURG, Ill., May 14, 2009 — The judges for the 2009 Direct Digital Manufacturing Competition were greatly encouraged by the increased number of entries for this year, and by the fact that some institutions had become newly involved including, for the first time, an entry from a high school. Once again, there were some very high-quality entries from colleges and universities, and the choice of winner in this category was a very close decision. The winner and runners-up are as follows:

First Place: James Potter, Heather Humphreys, Yang Xie and Raphael Okereke, Georgia Institute of Technology (Atlanta)
Submission: Customized golf clubs with integrated sensors

Second Place: Marc Hanratty, Loughborough University (Loughborough, Leicestershire, England)
Submission: Computer speakers

Third Place: Kelly Alexander, University of Texas at Austin (Austin, Texas)
Submission: Rolling ball kinetic sculpture

  • Georgia Tech's first-place entry was an excellent example of utilizing the customization capabilities of DDM in a personal interaction device. The justification of the DDM process and material was sound.
  • Loughborough University's second-place entry was also as an excellent demonstration of using innovative design features made possible by DDM. However, justification for the DDM process and material was not as rigorous as required for the competition.
  • University of Texas at Austin's third-place entry showed some very innovative DDM design features, but did not fully reflect the competition's requirement for a personal convenience or interaction device.

In the high school category, there was just one entry from the Downingtown High School (Downingtown, Pa.) — a combined snow shovel/weed extractor. The students have done a good job of modeling the product in CAD and are to be congratulated for grasping some of the possibilities offered by DDM. To reward their efforts and to encourage future participation by other high schools, the judges awarded the first prize (High School Category) to Downingtown. The winning and runners-up designs were built as DDM parts and were on display at the RAPID 2009 Conference & Exposition held May 12-14 in Schaumburg, Ill. The models will be returned to the student(s) who designed them.
