This report describes the results of an analysis tracing the technological influence of additive manufacturing research funded by the U.S. Department of Energy (DOE)’s Advanced Manufacturing Office (AMO) and its precursor programs, as well as additive manufacturing research funded by other offices in DOE (Other DOE). Over the short period in which AMO has funded additive manufacturing research, 20 additive manufacturing patents are confirmed to be associated with AMO funding (16 U.S. patents, one EPO patent, and three WIPO patents). Note that the AMO-funded patents are all relatively recent, with the earliest being filed in 2007. The influence of DOE-funded additive manufacturing patents can be seen both within additive manufacturing technology, and in other technologies such as electronics, semiconductors, advanced materials and medical devices.
