Traditionally, part manufacturing has been by shaping and molding materials using fixturing and tooling. In the 1980s, incorporating information technologies into manufacturing technology, a specialized research area emerged that defined a part as an enormous collection of carefully arranged microscopic bits of material that were incrementally fused together. Its simplicity offered a new paradigm for part manufacturing with the benefit of mass customization at a near constant unit cost. Called additive manufacturing, the field grew, patents were filed, international standards were proposed, and startups were spun-out. With impressive improvements in computing and sensing, new growth in the field fostered the "maker" movement. Its next chapters involve the intertwining of cyber-physical systems, advanced materials, and even biological processes. In this talk we will present a retrospective of government investments in additive manufacturing R&D and discuss a future for cyber-enabled additive manufacturing that is responsive to concerns of certification, safety, and security.
