DOE/Oak Ridge National Laboratory Oak Ridge National Laboratory researchers have conducted a comprehensive life cycle, cost and carbon emissions analysis on 3D-printed molds for precast concrete and determined the method is economically beneficial compared to conventional wood molds. Precast concrete is used in building construction and produced by pouring the material into a reusable mold. For decades, these molds have been made from wood — a technique that requires a highly specialized skillset.
