The WTEC workshop on European R&D in Additive/Subtractive Manufacturing, was held at the National Science Foundation (NSF) on December 2, 2003. At the workshop, WTEC's panel of experts focused on the latest work going on in Europe.

Purpose and Scope

The goal of this study is to gather information on the worldwide status and trends in additive/subtractive manufacturing S&T and disseminate it to government decision makers and the research community. The study panelists will gather information on S&T research at home and abroad useful to the U.S. government for planning its research investments, and will critically analyze and compare the research in the United States with that being pursued abroad. This information will serve the following purposes:

The solid freeform fabrication (SFF) community has learned that 2-D design decomposition allows layered deposition of structures with increasing geometric complexity. However, restriction to layered SFF techniques may be constraining regarding part quality and material variety. Clearly, additive material processes are broader than just layered processes, but even they do not include material subtraction, assembly, and insertion of components made by other processes. Therefore this study will focus on the broader topic of integrative approaches to "material synthesis."

Subtopics likely to be covered in this WTEC study include the following:

The study may also address the following non-technical issues:

The above list of topics may be refined by panel members in consultation with the sponsors.
