Atlanta-based Quikrete Companies and the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory, Tennessee, have entered a cooperative research and development agreement to design next-generation concrete for production of large-scale structures or elements through a 3D printing process (see “Sweet Success,” page 50). Using an Oak Ridge-developed additive manufacturing system, the two-phase, two-year collaboration will target specially-formulated mixes spawning new construction capabilities.

A $250,000 infusion from the Colorado Office of Economic Development and International Trade’s Advanced Industries Accelerator Grant Program will position Boulder-based concrete construction specialist RCAM Technologies and technology integrator Accucode Inc. to develop wind energy components using 3D printing methods. The grant supports RCAM work on a concrete wind turbine foundation with the potential to reduce offshore deployment costs by up to $4 million per structure and $400 million per plant. The firm will use the funding to expand its 3D concrete printing capabilities at two Colorado partner locations: the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) in Golden, and Accucode’s new Colorado Springs facility.
