The electron beam free form fabrication process (EBFFF) holds great promise for industry as a disruptive technology based on additive manufacturing of near net shape, high value engineered materials. The development efforts are structured to review and compare multiple process feedback systems for… More

Electron Beam Free Form Fabrication has the potential to produce large titanium structures directly from 3D models eliminating or reducing the long lead times associated with designing, procuring, and implementing conventional forging tooling as well as reducing the amount of machining cost by… More

Work proposed for this Phase I involves utilizing existing EBDM technology with newly incorporated closed loop process controls to develop optimized parameters for thermal management of the process intended to improve microstructure and mechanical properties over those previously obtained using high… More

ABSTRACT: Using a combination of sensing methods we shall demonstrate full closed loop computer control of the electron beam direct manufacturing processes as it relates to high deposition rate titanium. The control will vary multiple process parameters in response to direct molten pool… More

The proposed scope of work is intended to comprise efforts to implement a production capable Electron Beam Direct Manufacturing (EBDM)system intended to produce parts with sufficient quality and affordability to meet Air Force program requirements. The scope deals not only with the EBDM process… More
