Abstract Scope |
Large-format metal directed energy deposition (DED) additive manufacturing (AM) methods are increasingly being evaluated for domestic production of high-mix, low-volume casting replacements critical to the energy and defense industries. Maximizing the return of future research efforts and industry adoption hinges on understanding the technoeconomic (TEA, e.g., manufacturing cost) and life-cycle (LCA, e.g., embodied emissions) analyses of each process compared to existing conventional manufacturing processes. We present TEA and LCA metrics (e.g., build rate and volume, resolution, feedstock cost, specific embodied energy and CO2e) for several mature (e.g., wire-arc, laser blown-powder, hot-wire) and emerging DED processes located at the Oak Ridge National Laboratory Manufacturing Demonstration Facility, draw comparisons to conventional manufacturing processes, and highlight areas of opportunity for future development. |
