This document discusses emerging production technologies like additive manufacturing (3D printing) and whether their adoption constitutes a "fourth industrial revolution." It identifies several potential barriers to the uptake of these technologies, including issues around materials, design, skills/education, costs/investment, standards/regulation, testing, and intellectual property protection. The document argues that overcoming these barriers is important to improve the commercialization of new production technologies and maximize their impacts on business models, locations of production activities, and the skills and capabilities needed to create and capture value from them. It questions whether technological innovation alone will drive productivity growth or if broader changes are needed to fully realize the potential of emerging technologies.
