A Brief History of Additive Manufacturing and the 2009 Roadmap for Additive Manufacturing: Looking Back and Looking Ahead

Additive Manufacturing (AM) has roots in topography and photosculpture which date back almost 150 years. Both of these early technologies might be categorized as manual "cut and stack" approaches to building a freeformed object in a layerwise fashion. The first successful AM process was effectively a powder deposition method with an energy beam proposed by Ciraud in 1972. Other historical developments in AM will be described in the presentation. Transitioning from the oldest developments in AM to the most recent, earlier this year sixty-five experts in AM gathered in the Washington DC area to develop a research roadmap for AM. The results of that effort are described.
