Smart manufacturing technologies, including additive techniques like 3D printing, networked equipment and computer modeling to monitor and adjust production, and end-to-end digital tracking of materials and finished products, are already helping to improve the productivity, energy efficiency, competitiveness and sustainability of U.S. manufacturing. This report, assembled by a National Academies committee that included SME Chief Workforce Development officer Jeannine Kunz and SME Board of Directors Member Jian Cao, explores technologies transforming the manufacturing sector and identifies both resources and research that will speed the adoption of smart manufacturing. The report also makes recommendations to address critical needs in workforce development and education that will help to train the next generation of the manufacturing workforce.
