Session 4: Free Form Fabrication
Location: Room 305 (Dayton Convention Center )
(Please check final room assignments on-site).
Session Description: This session will discuss the latest developments in the fabrication of titanium components via the interaction of Ti powder or wire with an electron or laser beam to build a near-net shape on a substrate. The session will start with a discussion on aerospace requirements for this type of product and will include theoretical discussions, experience and techniques in building these shapes and properties resulting from this type of processing.

Session Chair:Karen M. B. Taminger NASA Langley Research Center, Hampton, VA
