Master's students use ideas from my (Jeff Funk) forthcoming book (Technology Change and the Rise of New Industries) to analyze the technical and economic feasibility of 3D additive printing. Manufacturing parts using additive fabrication techniques can enable on-demand local manufacturing and thus can eliminate complex value chains. See my other slides for details on concepts, methodology, and other new industries..

Technology Technology
• Mass‐production • Allow customization and
on‐demand production
• Require tools to produce • Directly manufacture from
