3D Printing: Opportunities, Challenges, and Policy Implications of Additive Manufacturing, Highlights of a Forum Convened by the Comptroller General of the United States, Report to the Chairman, Committee on Science, Space, and Technology, House of Representatives   [open pdf - 7MB]

"Additive manufacturing has the potential to fundamentally change the production and distribution of goods. Unlike conventional or subtractive manufacturing processes, such as drilling, which create a part by cutting away material, additive manufacturing builds a part using a layer-by-layer process. Additive manufacturing has been used as a design and prototyping tool, but the focus of additive manufacturing is now shifting to the direct production of functional parts- parts that accomplish one or more functions, such as medical implants or aircraft engine parts-that are ready for distribution and sale. On October 15-16, 2014, GAO [Government Accountability Office], with the assistance of the National Academies, convened a forum to discuss the use of additive manufacturing to directly produce functional parts, including its (1) opportunities, (2) key challenges, and (3) key considerations for any policy actions that could affect its future use. Forum participants included officials from government, business, academia, and nongovernmental organizations that were selected to represent a range of viewpoints and backgrounds. This report summarizes the ideas and themes that emerged during the forum and the collective discussions of the forum participants. This report does not necessarily represent the views of the organizations whose representatives participated in the forum, including GAO. Participants were given the opportunity to comment on a draft of this report and their technical comments were incorporated, as appropriate."
