Allied Spirit is a U.S. Army exercise for multinational partners, conducted at 7th Army Training Command training areas at Grafenwoehr and Hohenfels, Germany.

Unlike other USAREUR-AF exercises, which feature U.S. brigade combat teams in a lead role augmented by Allies and partners, Allied Spirit places an Allied unit as the main training audience. While U.S.-led, this exercise will develop and enhance NATO and key partner interoperability and readiness across specified warfighting functions.

Sequestering Dredged Sediment Contaminants for Beneficial Use Applications in 3D-Printed Structures - Unbranded

The U.S. Army Corps of Engineers has set an ambitious goal to beneficially use 70 percent of its dredged sediment by 2030. It’s a big challenge that will require innovative solutions for fine-grained dredged sediments that cannot be used for traditional applications, such as beach nourishment.

Researchers at the U.S. Army Engineer Research and Development Center’s (ERDC) Environmental Laboratory are working to overcome these challenges as they develop methods for deploying dredged sediment as feeder stock in 3D printing.

Beyond the mechanical processes of using dredged sediment for 3D printing, ERDC researchers are also pioneering pre- and post-processing methods to help determine the material’s feasibility for being safely reintroduced into the environment.

These printed structures will be used to enhance habitat, infrastructure, sediment containment, and energy dissipation, among other benefits. Little data on these processes currently exists and ERDC is looking to close that knowledge gap. Watch to learn more.
