Abstract
The TRB Conference on Advancing Additive Manufacturing and Construction in Transportation was held November 7–8, 2024, at the Arnold and Mabel Beckman Center in Irvine, CA. The Additive Manufacturing (AM) process and Additive Construction (AC) applications are linked by 3D printing technical concepts. This global forum identified future transportation research needs by providing an idea of what is possible based on how the technology is being used now.
