Advanced manufacturing, loosely defined as the integration of digital technology with physical manufacturing systems, is transforming how we design, develop, and manufacture products. From real-time process monitoring and control, to next-generation materials and product architectures, to flexible industrial automation, advanced manufacturing technologies are, and will continue to, unlock new horizons for product and operational possibilities. Yet, these technologies are still at the infancy of their impact. Challenges range from the often substantial capital expenditures required for new equipment, to limitations in design and application knowledge. For advanced manufacturing methods to realize their potential, we believe they must be accessible – in both technology and know-how – to those who can best put it to work.

The MIT Center for Advanced Production Technologies (APT) is dedicated to revolutionizing applied manufacturing science at MIT. APT operates state-of-the-art advanced manufacturing facilities on campus, with a core focus on additive manufacturing (AM). We collaborate with end-users to engineer sophisticated fabrication solutions for complex applications. Our work spans academic domains and audiences, supporting pioneering MIT research on new materials, geometries, and operational strategies. Beyond MIT, APT partners with industry to offer world-class education and training programs, engage in applied projects to develop new applications using digital production technologies, and serve as an open resource for those interested in exploring new production tools.
