Digital manufacturing model results in DARPA prize
A titanium mesh
sphere is
positioned in
an ORNL lab to be
crushed—destructive
testing to
obtain
parameters for DARPA's
$50,000 DMACE Challenge
The crushing of 180 digitally manufactured (DM) titanium mesh spheres has culminated in a $50,000 DARPA prize for a University of California at Santa Barbara team, who came up with the most accurate predictive model of the components' properties.
The competition, which subjected spheres produced at the DOE's Oak Ridge National Laboratory and polymer cubes produced at the Navy Postgraduate School in Monterey, Calif., to destructive testing, were part of DARPA's Digital Manufacturing Analysis, Correlation and Estimation (DMACE) Challenge to showcase the potential of digital manufacturing of advanced materials.
The $50,000 DMACE Challenge, conceived by participants in DARPA's three- month Service Chiefs' Fellows Program, drew 179 entries from 13 countries and 38 universities.
